Product Description
In regard to focusing performance, a ring-type Ultrasonic Motor offers fast, smooth, and near-silent autofocus, which is further benefitted by full-time manual focus operation and an internal focusing design. The lens is both water and dust-resistant, and fluorine coatings have also been applied to the front and rear elements to protect against fingerprints and smudges from affecting image quality.
- Wide-angle zoom 11-24mm f/4 lens is compatible with full-frame EOS DSLRs, as well as APS-C-sized sensors where it will provide a 17.6-38.4mm equivalent focal length range.
- Constant f/4 maximum aperture offers consistent performance and light transmission throughout the zoom range.
- One Super UD (Ultra Low Dispersion) and one UD element help to significantly reduce chromatic aberrations for improved clarity and color accuracy.
- Four aspherical elements help to minimize distortions throughout the zoom range in order to maintain edge-to-edge sharpness and illumination.
- Both a Subwavelength Coating (SWC) and an Air Sphere Coating (ASC) have been applied to lens elements to reduce backlit flaring and ghosting for maintained light transmission and high contrast in strong lighting conditions.
- A ring-type Ultrasonic Motor (USM), along with an internal focusing system, high-speed CPU, and optimized AF algorithms, are employed to deliver fast, precise, and near-silent autofocus performance.
- Full-time manual focus operation is available for fine-tuning of your focus position when working in the AF mode.
- A weather-resistant design protects the lens from dust and moisture to enable its use in inclement conditions. Additionally, fluorine coatings have also been applied to the front and rear lens elements for further protection against fingerprints and smudging.
- Nine rounded diaphragm blades contribute to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
- Lens' design accepts rear insert-type gelatin filters, which are cut-to-size and inserted behind the rear lens element.

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.”

“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!”
