BROADEN YOUR CREATIVE HORIZONS
Rethink what you know about ultrawide angle lenses. The RF 10-20MM F4L IS STM 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.

SEE THE WORLD AT 10MM
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.

Exaggerated perspective
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 us to design the most portable AF ultrawide ever, without compromising on quality or performance. At just 570g, it weighs 610g less than our EF 11-24mm f4L USM lens, despite offering a wider angle of view and an optical Image Stabilizer.

STEADY AND STABLE
Ultrawide lenses have many benefits, but a common problem is that image stabilisation in the far corners of the frame is hard to achieve without distortion. As a result, the corners of the frame can appear to be wobbly in video and blurred in still images. Peripheral Coordinated Control IS is designed to reduce distortion by using a new algorithm detects shake and maximises the lens’ optical IS to compensate for distortion.

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.

Built for the pros
Even in the most challenging conditions, the RF 10-20MM F4L IS STM shines. Its weather resistant L series construction satisfies the demands of professionals and ensures this lens will last for years.
