There’s ultrawide, and then there’s the RF 10-20MM F4L IS STM lens. With a widest focal length of just 10mm, it offers more ways to be creative with perspective foreground details. The lens takes full advantage of the advanced RF lens mount, and filmmakers will love it for the unique establishing and point-of-view shots it delivers. At 570 g, it’s lightweight, portable and still able to deliver a wider angle of view and new features, such as optimised STM focusing. A Peripheral Control Image Stabilizer stabilises photos and videos right to the corners of the frame, and image quality is incredible thanks to the advanced rectilinear optical design, taking your photography and filmmaking to new heights.
Wide-angle lens for landscape photography
Produce dramatic perspectives and sharper foreground details, thanks to an advanced optical formula and the unique Canon RF lens mount, for compositions that let your images stand out from the crowd.
Next-level architectural photography
Looking for a wide-angle lens for architectural photography? The rectilinear RF 10-20mm F4L IS STM lens keeps straight lines straight, even at the edges of the frame, thanks to aspherical lenses, plus UD and Super UD glass. With a widest focal length of 10mm, you can shoot in tight interior spaces, too.
Captivating video footage
Filmmakers looking to get creative with point-of-view shots will love this lens’ versatility. Plus, its optimised STM autofocus allows pull-focus transitions and smooth continuous focusing when shooting.
Smooth handheld images and video
A Peripheral Control Image Stabilizer gives up to 5 stops of protection against camera shake when shooting still – 6 stops when used with an EOS R system camera featuring in-body stabilisation. Filmmakers can expect smooth, wobble-free footage, even in the far corners of the frame.
Built for pros
Professionals know that Canon L-Series lenses won’t let them down, and the RF 10-20mm F4L IS STM lens is no exception. Robust, weather-resistant construction means you can shoot with confidence even when conditions turn bad. A built-in lens hood and fluorine coating protect the front element.
Customisable controls to work how you want
A customisable lens control ring and AF stop button are easy to find instinctively, without removing the camera from your eye. Program them from your camera’s menu to perform actions that will help you in the way you work.
Light enough to take everywhere
The RF 10-20mm F4L IS STM lens weighs just 570 g, so you can take it to more places and capture an ultrawide viewpoint more often.
Constant f/4 maximum aperture
The lens’ maximum aperture of f/4 doesn’t change through its zoom range, so exposures remain constant. A bonus for filmmakers, too.

- *For cameras with an APS-C sized sensor, a crop factor applies giving an equivalent focal length of 1.6x – this means that the 10-20mm on an APS-C camera will give the field of view equivalent to a 16-32mm lens on a Full Frame camera. Check camera user manual for further details.
