Offering an expansive field of view to suit selfie, landscape, cityscape, and other wide-angle applications, this lens also offers fast, precise, and quiet autofocus performance as well as excellent close-up performance at all focal lengths.
- Engineered for use with full-frame Sony E-mount mirrorless cameras, the lens's constant f/4 maximum aperture maintains consistent illumination throughout the entire zoom range.
- Features a combination of three ED elements, two AA elements, one ED aspherical element, and one standard aspherical element to effectively eliminate chromatic and spherical aberrations while also rendering excellent edge-to-edge sharpness and color fidelity.
- Rounded 9-blade aperture provides deep, soft bokeh.
- Two XD (extreme dynamic) linear motors provide smooth, silent, and precise autofocus performance as well as improved tracking performance for photos and videos.
- Internal focusing system maintains the overall length of the lens and does not rotate the lens barrel while focusing, enhancing the use of circular polarizers and variable ND filters.
- Updated optical design effectively eliminates focus breathing, focus shift, and axial shift to prevent unwanted movements and angle of view variations during movie recording.
- Aperture ring with On/Off click switch and iris lock switch prevents the aperture ring from being accidentally moved between the f/4 and f/22 settings.
- Optimized for filming, the lens supports active mode image stabilization and micro-step aperture control for smooth and seamless video capture.
- Two programmable focus hold buttons and a focus mode switch for intuitive focus control.
- Minimum focusing distance of 9.8" with excellent close-up performance at all focal lengths.
- Hybrid construction uses both metal and plastic components to maximize both durability and a low weight design.
- Fluorine coating on front lens element repels water, dust, fingerprints, and other contaminants while also making it easier to clean the front of the lens.
- Dust and moisture-resistant design includes a rubber ring to seal the lens mount for working in inclement weather conditions.

From ultra-wide 20 mm to 70 mm
With an unprecedented1 ultra-wide 20 mm to short-telephoto 70 mm zoom range, this versatile lens is an excellent choice for a wide range of movie and still subjects. The ultra-wide 20 mm end of the zoom range maintains a wide angle of view when shooting movies with a 16:9 or 2.35:1 aspect ratio that reduces view angle.Outstanding G Lens image quality
With two AA (advanced aspherical) elements, one aspherical element, three ED (Extra-low Dispersion) glass elements, and one ED aspherical element, this state-of-the-art lens design corrects both chromatic and spherical aberration for high optical performance right out to the image edges, from ultra-wide 20 mm to 70 mm.Excellent close-up performance
AA (advanced aspherical) elements help to achieve a minimum focus distance of 0.98 feet (wide) to 0.82 feet (telephoto) when using AF, and 0.82 feet throughout the zoom range when focusing manually. Maximum magnification is 0.39x for detailed close-ups. Close focus makes it easy to maneuver around small subjects to find the idea angle.Constant F4 maximum aperture
A constant F4 maximum aperture offers greater flexibility in choosing apertures at any focal length. The selected aperture remains constant throughout the zoom range. There is no need to use extreme ISO settings at the telephoto end of the range, and high shutter speeds can be used as needed to achieve the desired effect.Compact, lightweight, mobile design
This compact, lightweight lens combines state-of-the-art optical design with Sony's high-thrust XD (extreme dynamic) Linear Motor technology. Used with a compact mirrorless body, it can deliver superb image quality in any situation at focal lengths from ultra-wide to short telephoto. A great choice for shooting with minimum gear.Peak AF performance for stills and movies
Two XD (extreme dynamic) Linear Motors achieve fast, quiet, smooth focus drive with up to 60% higher AF speed2 and up to two times2 better performance while tracking2 for reliable, precise tracking. Moving subjects are reliably tracked when shooting continuous stills at up to 30fps3, and high-frame-rate movie capture is smooth.Refined movie imagery
Advanced technology reduces focus breathing as well as focus and axial shift when zooming so that distracting image shifts are minimized. XD Linear Motors and a newly developed aperture unit dramatically reduce noise and vibration when shooting movies. The breathing compensation function provided in compatible α series bodies4 is also supported.Active Mode5 supports ultra-wide images
Active Mode5 image stabilization in α series cameras works effectively at the ultra-wide 20 mm end of the zoom range, providing excellent image stabilization performance while maintaining a wide angle of view. This can be particularly useful for shooting smooth, stable handheld footage while walking.Focus hold buttons and focus mode switch
Customizable focus hold buttons are provided in two locations for easy access and control. Other functions can be assigned to the focus hold button from the body menus to match shooting needs. A focus mode switch makes it possible to switch between autofocus and manual focus on the fly, to quickly adapt to changing shooting conditions.Lens Specifications | |
