Rethink what you know about ultra-wide angle lenses. The Canon RF 10-20mm f/4 L IS STM Lens is the widest-angle AF zoom in the world,* offering class-leading image quality and portability. Yet another example of how the Canon EOS R system is changing the game for professional photographers and filmmakers.

The RF 10-20MM F4L IS STM is the widest AF zoom ever made for a full-frame camera*, with a huge angle of view of up to 130˚, letting you put 16% more in the frame than a 12mm lens. Shoot immersive perspectives at close quarters and make foreground objects work harder in your landscape work.

Wide-angle focal lengths exaggerate the distance between objects, giving photos and video a sense of depth. The RF 10-20MM F4L IS STM takes this to the next level – get in close and shoot ultrawide for a dramatically different view of the world.

Ultrawide, ultra-portable

The advanced nature of the RF lens mount allowed Canon to design the most portable AF ultra-wide ever, without compromising on quality or performance. At just 570g, it weighs 610g less than Canons EF 11-24mm f4L USM lens, despite offering a wider angle of view and an optical Image Stabiliser.

Every detail, perfectly reproduced

Expect incredible clarity and low distortion, with straight lines remaining straight even at the edges of the frame. Superb sharpness comes from an advanced optical formula that uses glass moulded aspherical elements, UD and Super UD glass, and state-of-the-art optical coatings.

Smooth and quiet focusing

Optimised STM autofocus delivers a professional performance – focusing quickly and accurately in virtual silence. Filmmakers will love its smooth video focusing.
