Canon RF 10-20mm f/4 L IS STM

The Canon RF 10-20mm f/4 L IS STM lens is designed for Canon full-frame mount cameras and offers a fast ultra-wide zoom capability. It has a focal length range of 10-20mm, making it ideal for landscape, architecture, and wide-angle photography. The lens has a variable aperture range of f/4 to f/22, allowing for flexibility in controlling depth of field and capturing images in various lighting conditions. With its ultra-wide zoom range of 10-20mm, the lens enables you to capture expansive scenes and add a sense of depth and scale to your images.

The lens features an optical image stabilizer that helps minimize the effect of camera shake, allowing for sharper handheld shots, even in low-light situations. The lens utilizes a high-speed STM autofocus system, enabling quick and accurate autofocus performance, whether shooting stills or videos. It incorporates advanced coatings, including Air Sphere Coating (ASC) and Subwavelength Structure Coating (SWC), which help reduce flare and ghosting, resulting in improved image clarity and contrast. With one Super Ultra-Low Dispersion (UD) and three UD elements, the lens effectively corrects chromatic aberrations, ensuring excellent image quality and color accuracy.

The lens features a programmable Control Ring that can be customized to adjust various settings, such as aperture or ISO, providing a more intuitive shooting experience. The lens is designed with weather sealing, making it resistant to dust and moisture. This allows you to confidently use it in various outdoor shooting conditions.

The Canon RF 10-20mm f/4 L IS STM lens is a versatile wide-angle zoom lens that offers excellent image quality, quick autofocus performance, and image stabilization. Its durable construction and weather-sealing make it an ideal choice for photographers who require a reliable lens for their outdoor and wide-angle photography needs.

Product Features in Detail

Modern Design
The design of this lens is geared toward getting the job done efficiently with light weight, fast focusing, image stabilization, and a programmable control ring. There is even a petal-type lens hood built right into the barrel of the lens.

Incredible Dimensions
Capturing images at 10mm is already pretty special, but to do it in a lens that is lighter and smaller than even our own EF11-24mm f/4 L USM is quite a feat. The RF mount design allows for the possibility of this wider-angle lens range and is also a key factor in the size and weight reduction of the lens. This also enables the addition of IS (image stabilization) in a lens that otherwise might not be able to have it.

Excellent Image Quality
Again, thanks to the Canon RF lens mount, the RF10-20mm F4 L IS STM lens offers great optical quality. Its optical design includes one super UD element, three UD elements and three aspheric elements (including large-diameter aspheric and UD aspheric elements) as well as Subwavelength structure coating (SWC) and Air Sphere Coating (ASC) to reduce ghosting. On top of that, this lens features the same dust- and water- resistance found on L-series lenses with seals around the Control ring, focus ring, zoom ring, operation panel, and lens mount.

Make Some Movies
The RF10-20mm F4 L IS STM lens has a lot of advantages and features when it comes to video. First, you can take full advantage of the 10mm focal length on full-frame cameras, and you can even shoot 4K 60p without crop mode. If you are shooting on an APS-C camera, you’ll have access to wider angles than you ever have before (coverage equivalent to a 16-32mm lens).  Another video advantage is the fixed f/4 aperture, minimizing exposure changes while zooming.

Optical Image Stabilization - Up to 5.0 stops of Shake Correction  
For consistently sharp results, the RF10-20mm F4 L IS STM features built-in optical Image Stabilization, providing enhanced shake reduction for up to 5.0 stops of shake correction. When paired with an EOS R-series camera that has In-Body Image Stabilization (IBIS), the Coordinated IS allows for up to 6.0 stops of correction.  Steady hand-held video, and incredibly sharp still images, are the benefits of this new RF ultra-wide-angle lens.

High-speed, Smooth and Quiet Autofocus
With any Canon EOS R-series camera, expect swift and positive autofocus. The STM leadscrew-type focus drive system is especially beneficial to video users, because of its combination of quiet operation and outstanding smoothness of focus changes during actual recording. And AF during still shooting is quick and equally quiet.

Get Close
With a minimum focus distance of just under 10 inches you can capture some really incredible ultra-wide-angle close-ups for a look unlike anything else.
