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

The Canon RF 10-20mm f/4 L IS STM Lens is a professional ultra-wide-angle L-series zoom lens designed for Canon RF-mount full-frame mirrorless cameras. It is one of Canon’s most advanced ultra-wide lenses, offering an extreme field of view, constant f/4 aperture, and built-in image stabilization.

This lens is ideal for landscape, architecture, real estate, interior photography, astrophotography, and cinematic video production, where maximum width and edge-to-edge clarity are required.

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,1 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 camera1, with a huge angle of view of up to 130Ëš, 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.
