Product Description
An all-arounder that pushes beyond basic, the Sony Alpha a7 IV does double duty with strong stills and video performance. An advanced hybrid mirrorless camera, the a7 IV has the resolution and AF performance that appeals to photographers along with robust 4K 60p video recording for filmmakers and content creators.
The newly developed 33MP Exmor R CMOS sensor pairs with the BIONZ XR processor from Alpha 1 to achieve quick shooting up to 10 fps and 4K 60p video recording, along with broad sensitivity up to ISO 51200 and a wide 15+ stop dynamic range. Beyond image quality, the sensor and processor also contribute to an advanced AI-based AF system that supports Real-time Eye AF and Real-time Tracking for intuitive AF control and subject tracking.
This fourth generation of the a7 camera also sports an updated body design that houses a higher resolution 3.68m-dot EVF, vari-angle touchscreen LCD, and dual memory card slots, including one dual CFexpress Type A/SD UHS-II slot. Connectivity and streaming is also a key attribute of this camera, and it supports a simple plug-and-play design for live streaming directly from the camera when connected to a computer via USB.
Sensor and Processor
33MP Exmor R BSI CMOS Sensor
The newly developed 33MP Exmor R full-frame sensor features a back-illuminated design that promotes high clarity, low noise, and vivid color rendering. This design benefits working in low-light conditions and works in conjunction with a broad sensitivity range of ISO 100-51200. The sensor's design also achieves an impressive dynamic range of approximately 15 stops and files can be recorded in raw, JPEG, or the 10-bit HEIF format.
BIONZ XR Processor
Using the flagship-class BIONZ XR engine, high-speed image processing capabilities are available for fast continuous shooting, 4K video recording, and advanced AF tracking performance. The quick processing also helps to reduce rolling shutter and other motion distortions for the clean rendering of moving subjects.
In terms of shooting speeds, the sensor and processor enable up to 10 fps shooting, using either the mechanical or electronic shutter and with AF/AE enabled. Also, the buffer permits recording up to 828 consecutive uncompressed raw + JPEG frames when using a CFexpress Type A card.

Advanced External Flash Control
Suiting working with flash while photographing fast-moving subjects, P-TTL flash metering is possible in between each exposure when working with lo, mid, or even hi-speed continuous shooting modes. This helps to maintain stable illumination if making low-light bursts and greatly benefits working in changing light or low-light conditions. The updated flash control system also helps to reduce flash trigger lag, uses the camera's AWB information for natural color rendering, and supports adjusting select flash and transmitter units directly from the camera's interface.
Video Recording
4K 60p Video Recording in 10-Bit
- Making full use of the high-resolution 33MP sensor and fast processing capabilities, UHD 4K 30p XAVC HS 10-bit recording is possible using the full width of the sensor, offering 7K oversampling for impressive sharpness and realism.
- There is also oversampled 4K recording, via a 4.6K capture area, with a Super 35 crop, that offers UHD 4K output up to 60p in 10-bit.
- No recording time limit allows for unlimited clip lengths and the camera's physical design features an improved heat-dissipating structure to promote longer possible recording times; longer than one hour of continuous 4K 60p 10-bit 4:2:2 recording, for example.
- The a7 IV employs a pair of codecs to suit different workflows: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates, and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.
S-Cinetone, S-Log3, and Other Color and Gamma Controls
- S-Cinetone can be used to deliver distinct colors and healthy-looking skin tone rendering that matches the FX9 and FX6 cameras, along with the a1 and a7S III, and is based on technology from the professional Cinema Line cameras, such as the VENICE. This color profile offers natural mid-tones, soft colors, and especially well-controlled highlights.
- HLG (Hybrid Log-Gamma) support permits recording within a wide color gamut for producing HDR-ready content directly from the camera.
- S-Log3 is also available for producing a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
Fast Hybrid AF System
AI-Based Autofocus
Covering approximately 94% of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points for quick and precise focusing in a variety of lighting conditions with sensitivity down to -4 EV. This focusing system is available for use in all recording modes, to benefit both video and still applications.
Real-time Tracking and Real-time Eye AF
Borrowing from the flagship AF system, the a7 IV has tuned tracking and subject detection capabilities that lock onto subjects quickly and refines focus accurately on recognized eyes and faces of subjects:
- Real-time Tracking is an AI-based subject recognition system that recognizes color, pattern, and subject distance information for high accuracy and focusing speed.
- Beyond just tracking subjects, Real-time Eye AF fine-tunes the focusing accuracy and recognizes human, animal, and bird's eyes for critical sharpness. Real-time Eye AF even maintains focus on a subject's eye when they leave and re-enter the frame, allowing for working in more spontaneous shooting situations.
AF During Video Recording and Additional Focusing Modes
- Real-time Eye AF is fully supported during video recording, for subject detection and tracking of human, animal, and bird eyes while shooting.
- For more control over how focus shifts appear during recording, seven-step AF transition speeds and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur.
- A unique solution to compensate for how certain lenses perform when racking focus, Focus Breathing compensation will automatically smooth focus transitions and maintain a consistent field of view when changing the focus position during a shot. This mode crops into the image slightly and corrects for any detected shifts in composition when focusing is happening.
- Focus Map is a unique way of visualizing depth of field and functions in a similar way to peaking with a colorful overlay of the scene that indicates which parts of the scene are in front of and behind the focus point depending on the chosen aperture.
- A feature carried over from the FX6 digital cine camera, AF Assist lets you intuitively switch over to manual focus control for adjusting focus position when working with AF. This is a quick way to shift selective focus between various subjects in a scene while recording.
Body Design, Connectivity, and Streaming
Viewfinder and LCD Screen
- An improved QVGA OLED Tru-Finder EVF features a 3.68m-dot resolution that is approximately 1.6x higher in resolution than its predecessor for sharper, clearer viewing. This viewfinder supports both standard 60 fps and 120 fps frame rates for smooth motion rendering and its physical design has a long 23mm eyepoint, 0.78x-magnification, and 37.3° field of view.
- Perfect for vlogging or other self-recording needs, the side-opening 3.0" 1.03m-dot vari-angle articulating screen can be used in a front-facing orientation or can be tilted up or down to suit working from high or low shooting angles. This LCD is a touchscreen, too, for intuitive shooting control and menu navigation.
Hybrid Stills and Video Body Design

- Both 3.5mm headphone and external microphone ports facilitate greater control over audio recording.
- Multi-Interface Shoe supports working with the optional ECM-B1M Shotgun Microphone or XLR-K3M XLR Adapter Kit, which provides improved, clear audio recording sound by sending a digital audio signal to the camera, opposed to an analog signal.
- USB Type-C port can be paired with an optional Ethernet wired LAN adapter to provide 1000BASE-T connectivity, wired remote shooting, or FTP transferring.
5-Axis SteadyShot INSIDE Image Stabilization
- Enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system compensates for five different types of camera shake encountered during handheld shooting of stills and video and allows users to confidently use any lens, even adapted lenses, for critical shooting without encountering blur from camera shake.
- For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
- Additionally, specifically for video, there is also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of the camera.
Wireless Connectivity and Streaming

The BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x4 increase in processing speed. The engine concentrates real-time processing of AF, image recognition, and image quality adjustment to minimize processing latency, for greatly increased movie and still processing power. User interface, network, and file management processing is distributed in order to deliver fast response regardless of real-time processing load..jpg)
Beautiful image rendering with low noise
Visible benefits of the powerful new 33.0‑MP1 sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery, and better color reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout..jpg)
Smoother gradation rendering with 10-bit HEIF recording
The α7 IV offers HEIF (High Efficiency Image File)5 still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects, and the use of 10-bit depth minimizes degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV via an HDMI connection to display images with an extraordinarily wide dynamic range..jpg)
4K 60p2 recording, 4:2:2 10-bit recording
The α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p2 recording, and when recording 4K movies at 30p, full-frame 7K6 oversampling7 produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS™ file format8 provides roughly twice the coding efficiency of MPEG-4 AVC/H.264..jpg)
Set the mood, in-camera, with Creative Look
Broaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies, and live streaming, and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting..jpg)
Beautiful color expression made simple, with S-Cinetone™
The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6, and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin color, plus soft colors and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing..jpg)
S-Log for color matching with professional video equipment
The α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops9 of dynamic range. The S-Gamut3 and S-Gamut3.Cine color gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800, and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra-low noise..jpg)
Soft Skin Effect for bright and beautiful skin appearance
The built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes, and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available10, so you can adjust the degree of the effect as you wish..jpg)
Optical 5-axis in-body image stabilization for 5.5-step11 compensation
The α7 IV's high-precision stabilization unit and gyro sensors work with stabilization algorithms to achieve up to 5.5 steps11 of shutter-speed compensation, to maximize the performance of the camera's 33.0‑MP1 sensor. This in-body stabilization allows effective use with a wide range of lenses. The live monitor view shows the stabilized still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens, and it can be used in conjunction with the MF Assist and Focus Magnifier features..jpg)
Hand-held movie shooting with Active Mode12
Active Mode12 uses the camera's stabilization unit, gyro sensors, and sophisticated algorithms for highly effective in-camera optical image stabilization during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilization in all formats13, including 4K, without compromising the α7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilization can be applied for ultra-smooth shots using Catalyst Browse/Prepare software14..jpg)
Buffer memory supports continuous shooting and recording
Both the mechanical and electronic shutters allow continuous shooting at up to 10 fps15 with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 80016 uncompressed RAW+JPEG frames (more than 1600 altogether), or more than 1,000 compressed RAW+JPEG frames (more than 2,000 altogether, up to a full memory card)17. Increased processing power also allows you to change menu settings even while data is being written to the memory card..jpg)
Fast Hybrid AF with improved speed, precision, and tracking
Using a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely, even on small subjects or on people posed in front of a night-time background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 75918 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analyzed in real time by the latest powerful processing engine to achieve the AF system's impressive results..jpg)
AI-based Real-time Eye AF and Real-time Tracking19
The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy20, while faster image processing yields higher accuracy when the subject is looking up, down, or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine..jpg)
Bird mode for Real-time Eye AF, now available in movies
The Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight..jpg)
AF control through touch operation
Touch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots..jpg)
AF Assist for seamless transitions to manual focus21
The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject..jpg)
Visualize depth of field during movie shoots with Focus Map22
The new Focus Map22 overlays focus information onto a live real-time display to show which areas are in or out of focus. Being able to clearly visualize depth of field in this way makes it easier to quickly set up your ideal focus point and depth of field during rehearsal. As a result, you can use the camera's excellent video definition and fast lenses to create impressive shots with shallow depth of field..jpg)
Breathing Compensation23 for consistent angle of view when focusing
For the first time in the α series, the α7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus24. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilization to shoot stable, consistent imagery..jpg)
Still/Movie/S&Q dial for quick access to hybrid capabilities
Befitting the α7 IV's status as a true hybrid camera, it comes equipped with a dedicated Still/Movie/S&Q dial to instantly switch between movies and stills. The dial switches the menus, functions, and custom settings of various controls between still and movie mode, and settings such as aperture and shutter speed are also maintained separately for stills and movies. S&Q mode can also be selected, for fast access to slow-motion or quick-motion shooting..jpg)
The latest mode-specific menus and customizable Rear dial R
The α7 IV's menus are specific to either stills or movies, and for easier navigation menus are configured to show three levels of hierarchy at once. Separate functions for stills and for movies can be assigned to various buttons and dials, including the new, freely customizable Rear dial R. With controls tailored to whichever shooting mode you are currently using, the flexible access provided by the Rear dial R contributes to greatly enhanced still- and movie-shooting efficiency..jpg)
Vari-angle LCD monitor for greater freedom when shooting
The large, side-opening 3.0-type 1.03-megadot25 touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings, and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting, or very low ground-level shots..jpg)
3.68‑megadot25 high-definition Quad-VGA OLED viewfinder
The α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3° FOV and a 23‑mm high eyepoint. With high resolution, improved electronic viewfinder image quality, and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments..jpg)
Communication features for easy sharing and distribution
The α7 IV is equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5‑GHz26 band in addition to the 2.4‑GHz27 band, for fast data transfer. Background FTP transfer of files can be set to occur automatically while shooting continues, and a USB Type-C® connector supports fast SuperSpeed USB 10‑Gbps (USB 3.2 Gen 2) data transfer..jpg)
Instant real-time live streaming via USB connection
Live streaming is as easy as connecting to a computer through a USB connection, and you can choose from four different output formats, including high-resolution 4K video28. You can select whichever configuration is best for current network conditions and the devices used, and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs..jpg)
High-capacity Z batteries and USB Power Delivery29
The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies29 and AC adapters. Battery drain can be minimized by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD30 can be connected to the camera's USB Type-C® port, for extended recording..jpg)
Heat management
To allow extended continuous recording, efficient heat dissipation is provided by Sony's proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilization while heat is efficiently dissipated..jpg)
Dual media slots, with CFexpress Type A support
Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards31, and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate 4K movie recording..jpg)
Reliable, robust engineering
We have improved the dust and moisture resistance32 of the α7 IV to provide outstanding reliability, even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button, and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover, and internal frame provides excellent durability..jpg)
Consideration for the environment and resource conservation
Sony's "Road to Zero" environmental plan was launched in 2010 with the ultimate goal of achieving a zero environmental footprint. Currently, nearly all plastic packaging materials for the α7 IV are recycled. Recyclable materials are also used for camera bodies whenever possible, reducing environmental burden without compromising functionality. While retaining state-of-the-art performance, we aim to further reduce energy and resource consumption to reduce the burden on the environment..jpg)
Imaging Edge Desktop™ / Imaging Edge Mobile™
Expand your creative horizons with Imaging Edge Desktop33 and Imaging Edge Mobile34. The Imaging Edge Desktop PC application lets you control and monitor shoots directly from your PC screen, preview photos, and develop RAW/HEIF data into high-quality photos for delivery. Imaging Edge Mobile applications use the Wi-Fi and Bluetooth® functionality of the α7 IV to provide a wide variety of convenient shooting and sharing functions..jpg)
Lossless compression RAW in three size
Three lossless-compression image sizes are available: L, M, and S. The L size [Lossless Comp (L)] provides the same level of image quality as uncompressed RAW files while reducing file size. The M and S sizes record fewer pixels than the L size, providing more manageable RAW files. Software update (ver. 1.1 or later) is required.| Lens | |

Product Information provided by the Manufacturer
α7 IV full-frame hybrid camera
The latest sensor, processing engine, and AI-based autofocus work in tandem with cutting-edge still-photography and movie-making technology to create a fresh, dynamic imaging experience. The α7 IV is the ideal hybrid, providing breathtaking still and movie imagery, along with flexible connectivity for on-the-spot transmission of your images.
Newly developed 33.0‑MP1 back-illuminated CMOS image sensor
The full-frame Exmor R™ CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p2. The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15-stop3 dynamic range on stills, and increased AF precision and focal stability.
BIONZ XR™ image processor for up to 8x4 processing speed
The BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x4 increase in processing speed. The engine concentrates real-time processing of AF, image recognition, and image quality adjustment to minimize processing latency, for greatly increased movie and still processing power. User interface, network, and file management processing is distributed in order to deliver fast response regardless of real-time processing load.
Beautiful image rendering with low noise
Visible benefits of the powerful new 33.0‑MP1 sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery, and better color reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.
Smoother gradation rendering with 10-bit HEIF recording
The α7 IV offers HEIF (High Efficiency Image File)5 still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects, and the use of 10-bit depth minimizes degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV via an HDMI connection to display images with an extraordinarily wide dynamic range.
4K 60p2 recording, 4:2:2 10-bit recording
The α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p2 recording, and when recording 4K movies at 30p, full-frame 7K6 oversampling7 produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS™ file format8 provides roughly twice the coding efficiency of MPEG-4 AVC/H.264.
Set the mood, in-camera, with Creative Look
Broaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies, and live streaming, and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting.
Beautiful color expression made simple, with S-Cinetone™
The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6, and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin color, plus soft colors and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing.
S-Log for color matching with professional video equipment
The α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops9 of dynamic range. The S-Gamut3 and S-Gamut3.Cine color gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800, and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra-low noise.
Soft Skin Effect for bright and beautiful skin appearance
The built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes, and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions, as well as enhancing still shots and movies. Four level settings are available10, so you can adjust the degree of the effect as you wish.
Optical 5-axis in-body image stabilization for 5.5-step11 compensation
The α7 IV's high-precision stabilization unit and gyro sensors work with stabilization algorithms to achieve up to 5.5 steps11 of shutter-speed compensation, to maximize the performance of the camera's 33.0‑MP1 sensor. This in-body stabilization allows effective use with a wide range of lenses. The live monitor view shows the stabilized still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens, and it can be used in conjunction with the MF Assist and Focus Magnifier features.
Hand-held movie shooting with Active Mode12
Active Mode12 uses the camera's stabilization unit, gyro sensors, and sophisticated algorithms for highly effective in-camera optical image stabilization during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilization in all formats13, including 4K, without compromising the α7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilization can be applied for ultra-smooth shots using Catalyst Browse/Prepare software14.
Buffer memory supports continuous shooting and recording
Both the mechanical and electronic shutters allow continuous shooting at up to 10 fps15 with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 80016 uncompressed RAW+JPEG frames (more than 1600 altogether), or more than 1,000 compressed RAW+JPEG frames (more than 2,000 altogether, up to a full memory card)17. Increased processing power also allows you to change menu settings even while data is being written to the memory card.
Fast Hybrid AF with improved speed, precision, and tracking
Using a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely, even on small subjects or on people posed in front of a night-time background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 75918 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analyzed in real time by the latest powerful processing engine to achieve the AF system's impressive results.
AI-based Real-time Eye AF and Real-time Tracking19
The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy20, while faster image processing yields higher accuracy when the subject is looking up, down, or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.
Bird mode for Real-time Eye AF, now available in movies
The Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimized AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.
AF control through touch operation
Touch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots.
AF Assist for seamless transitions to manual focus21
The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject.
Visualize depth of field during movie shoots with Focus Map22
The new Focus Map22 overlays focus information onto a live real-time display to show which areas are in or out of focus. Being able to clearly visualize depth of field in this way makes it easier to quickly set up your ideal focus point and depth of field during rehearsal. As a result, you can use the camera's excellent video definition and fast lenses to create impressive shots with shallow depth of field.
Breathing Compensation23 for consistent angle of view when focusing
For the first time in the α series, the α7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus24. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilization to shoot stable, consistent imagery.
Still/Movie/S&Q dial for quick access to hybrid capabilities
Befitting the α7 IV's status as a true hybrid camera, it comes equipped with a dedicated Still/Movie/S&Q dial to instantly switch between movies and stills. The dial switches the menus, functions, and custom settings of various controls between still and movie mode, and settings such as aperture and shutter speed are also maintained separately for stills and movies. S&Q mode can also be selected, for fast access to slow-motion or quick-motion shooting.
The latest mode-specific menus and customizable Rear dial R
The α7 IV's menus are specific to either stills or movies, and for easier navigation menus are configured to show three levels of hierarchy at once. Separate functions for stills and for movies can be assigned to various buttons and dials, including the new, freely customizable Rear dial R. With controls tailored to whichever shooting mode you are currently using, the flexible access provided by the Rear dial R contributes to greatly enhanced still- and movie-shooting efficiency.
Vari-angle LCD monitor for greater freedom when shooting
The large, side-opening 3.0-type 1.03-megadot25 touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings, and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting, or very low ground-level shots.
3.68‑megadot25 high-definition Quad-VGA OLED viewfinder
The α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3° FOV and a 23‑mm high eyepoint. With high resolution, improved electronic viewfinder image quality, and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.
Communication features for easy sharing and distribution
The α7 IV is equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5‑GHz26 band in addition to the 2.4‑GHz27 band, for fast data transfer. Background FTP transfer of files can be set to occur automatically while shooting continues, and a USB Type-C® connector supports fast SuperSpeed USB 10‑Gbps (USB 3.2 Gen 2) data transfer.
Instant real-time live streaming via USB connection
Live streaming is as easy as connecting to a computer through a USB connection, and you can choose from four different output formats, including high-resolution 4K video28. You can select whichever configuration is best for current network conditions and the devices used, and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.
High-capacity Z batteries and USB Power Delivery29
The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies29 and AC adapters. Battery drain can be minimized by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD30 can be connected to the camera's USB Type-C® port, for extended recording.
Heat management
To allow extended continuous recording, efficient heat dissipation is provided by Sony's proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilization while heat is efficiently dissipated.
Dual media slots, with CFexpress Type A support
Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards31, and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting, as well as high-resolution, high-bitrate 4K movie recording.
Reliable, robust engineering
We have improved the dust and moisture resistance32 of the α7 IV to provide outstanding reliability, even in challenging outdoor shooting environments. Design refinements include more sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button, and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover, and internal frame provides excellent durability.
Consideration for the environment and resource conservation
Sony's "Road to Zero" environmental plan was launched in 2010 with the ultimate goal of achieving a zero environmental footprint. Currently, nearly all plastic packaging materials for the α7 IV are recycled. Recyclable materials are also used for camera bodies whenever possible, reducing environmental burden without compromising functionality. While retaining state-of-the-art performance, we aim to further reduce energy and resource consumption to reduce the burden on the environment.
Imaging Edge Desktop™ / Imaging Edge Mobile™
Expand your creative horizons with Imaging Edge Desktop33 and Imaging Edge Mobile34. The Imaging Edge Desktop PC application lets you control and monitor shoots directly from your PC screen, preview photos, and develop RAW/HEIF data into high-quality photos for delivery. Imaging Edge Mobile applications use the Wi-Fi and Bluetooth® functionality of the α7 IV to provide a wide variety of convenient shooting and sharing functions.
Lossless compression RAW in three size
Three lossless-compression image sizes are available: L, M, and S. The L size [Lossless Comp (L)] provides the same level of image quality as uncompressed RAW files while reducing file size. The M and S sizes record fewer pixels than the L size, providing more manageable RAW files. Software update (ver. 1.1 or later) is required.My Review for α7 IV full-frame hybrid camera

Ordered a lens on Friday. Item was delivered to me on Monday. Arrived in excellent condition in perfect working order. Not only did I pay a very reasonable price, but the shipping was free ! I will definitely do business with Pixel Connection again should the need arise !
I cannot say enough good things about Pixel Connection. I've bought multiple camera bodies - new and used - from them, along with several lenses, and they simply cannot be beat. Super helpful on the phone, good prices, and willing to work with customers to make the right solution happen. Pixel Connection is where I look first when buying camera equipment.
I am a cosmetic dentist so my photography is very important to me. I needed my camera set up for ease of use and custom settings. Jesse and Sam are so knowledgeable. Those two men helped me quickly and the Pixel store is open until 7 pm so I was able to get this done before my next working day! I also noticed Pixel has everything one needs for cameras, video and audio, social media, drones and even film! Check this store out for yourself for quality service and products!
⭐⭐⭐⭐⭐
My latest experience with ThePixelConnection was absolutely phenomenal. Matt and Ari went above and beyond to ensure I got the camera I needed, even when it seemed impossible.
The item I needed was out of stock everywhere else, but they didn’t stop there—they took the extra step to contact the manufacturer directly and managed to secure a new unit straight from the factory. Thanks to their incredible effort, I received my camera just in time for an important event.
What truly sets ThePixelConnection apart is the personal touch they bring to every interaction. Unlike my experiences with B&H—which, while efficient and resourceful, often feel very clinical and transactional—ThePixelConnection makes you feel like a genuinely valued customer.
I’ve worked with B&H for years and spent a small fortune with them, but if ThePixelConnection has what I need, they’re always my first choice. Their team is passionate, knowledgeable, and deeply committed to ensuring you get exactly what you’re looking for.
Matt, in particular, is a seasoned professional with extensive expertise in photography and their product lineup. His guidance and dedication made the entire process effortless and stress-free.
If you’re looking for exceptional service from a team that truly values its customers, look no further than ThePixelConnection. They’ve earned my loyalty, and I can’t recommend them highly enough!

“Quick and easy and with the option for in-store pickup.”
March 18, 2025 by Yin (Virginia, US)
“I have pre-ordered two cameras with Pixel Connection and both times have been wonderful experiences. Staff have been kind and helpful both times. They provided updates weekly and even provided me an option to purchase a different color camera when it became available before my pre-ordered color. They were also prompt with their shipping once payment was completed!”
