Canon RF 10-20mm F4L IS STM 

See the world in ultrawide, with a lens that fuels your creativity.

Redefining the professional ultrawide-angle zoom lens with the RF 10-20mm F4L IS STM. Wider, smaller and with more features than its rivals, this lens empowers photographers and filmmakers with the performance they need to realise their creative ambitions.

Whatever you shoot, and wherever you shoot it, the RF 10-20mm F4L IS STM gives you extra creative options for photography and filmmaking. Ultrawide focal lengths from 10mm to 20mm let you put more in the frame and create dramatic perspectives. An advanced Image Stabilizer lets you shoot pin-sharp photos handheld in low light, as well as gimbal-smooth video. All this from a pro-grade lens that weighs just 570g – light enough to earn a permanent place in your bag.

The ultimate ultrawide for photos and video

Get more in the frame and create dramatic perspectives – Add  extra foreground interest and shoot tight interiors and architecture. It’s great for creative establishing shots when filmmaking too.

Ultrawide, ultraportable

Weighing just 570g, the RF 10-20mm F4L IS STM deserves a permanent place in your bag. Take the ultrawide viewpoint to more places more often and take a different perspective to usual.

Every detail – just how it should be

Expect incredible sharpness and clarity with virtually no distortion – so straight lines remain straight, even at the edges of the frame. All thanks to an advanced optical formula.

Stabilisation that just works

Photo or video. Centre or edge. A Peripheral Control Image Stabilizer gives up to five stops of protection against camera shake – six stops with an EOS featuring in-body stabilisation.

Built for the professionals

A constant f/4 maximum aperture gives consistent exposures through the zoom range. A lens function button and control ring allow instinctive shooting. Naturally, the RF 10-20mm F4L IS STM is resistant to dust and moisture too.

Ultrawide, ultracompact

The RF 10-20mm F4L IS STM is the widest AF zoom ever made for a full-frame camera*, with an angle of view up to 130?. The RF mount’s short back-focus and large lens-mount allow amazing image quality from a compact design.

In fact, the RF 10-20mm F4L IS STM is 610g lighter, and 2cm smaller in width and length, than the EF11-24mm F4L USM, despite offering a wider angle of view and more technology, such as IS.

The lens has three glass-moulded aspherical elements for high-resolution performance. Advanced lens coatings minimise ghosting and flare.
