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

Canon RF 10-20mm f/4 L IS STM - an infinitely wider perspective on photography and video production

The Canon RF 10-20mm f/4 L IS STM brings you a high-end ultra-wide-angle zoom lens designed specifically for landscape, architecture and interior photography - as well as video production where immersive angles are key. The standard f/4 aperture is maintained throughout the zoom range, ensuring smooth exposure and smooth working.

As an L-series lens, the RF 10-20mm f/4 has first-class optics. Aspherical and UD lens elements combined with Subwavelength Structure Coating and Super Spectra coatings keep distortion and reflections at bay - even in challenging backlight conditions. Images remain sharp and colours natural throughout the wide-angle range.

Although it's a wide-angle lens, Canon has equipped it with an optical image stabilizer of up to 5 stops. With IBIS stabilisation built into the Canon body, up to 6-step stabilisation gain can be achieved. The STM focusing motor makes focusing almost silent and smooth, which is especially important for video and indoor photography. Manual focusing is precise, and an adjustable adjustment ring allows you to fine-tune settings quickly.

Weighing only around 570 grams, the lens is easy to carry - even on landscape tours or in tight indoor spaces. The L Series' distinctive red ring and weatherproof construction complete the professional look.

Due to the curvature of the front lens, traditional circular filters cannot be attached, but a gel filter slot for ND or effect filters can be found on the back. A lens hood, front and rear caps and a storage bag are included, so you can set up immediately without any additional equipment.
