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

The Canon RF 10-20mm f/4 L IS STM lens builds on the capabilities of our latest RF mount as Canon’s widest RF zoom lens with an angle of view of up to 130°. Featuring a zoom ranging from 20mm wide-angle to an exceptional ultra-wide 10mm focal length, users can now achieve a shooting area more than a 16mm focal length.

Fitting more in the frame allows for fresh perspectives when capturing dramatic panoramas. Photographers can add extra foreground interest, capture tight interiors and architecture, and add depth to landscapes, and filmmakers can be more creative with awe-inspiring establishing shots.

Every Detail, Just As It Should Be

The new lens delivers incredible image quality in a wide-angle lens, achieving sharpness and clarity and substantially reduced distortion.

Engineered to the highest standard, the RF 10-20mm f/4L IS STM incorporates the latest Peripheral Control Image Stabilisation (IS) technology, which allows crystal-clear, shake-free images even in challenging shooting conditions or without tripod access. The new IS helps produce shake-free images from centre to the edge of the frame and offers five stops of optical stabilisation or six stops in combination with an in-body stabilised camera. Its advanced rectilinear optical design means you can expect a crisp and accurate outcome – so straight lines remain straight, even at the edges of the frame, all thanks to an advanced optical formula. A constant f/4 maximum aperture provides consistent exposures at every zoom setting, and state-of-the-art optical coatings minimise ghosting and flare, which can be common with ultra-wide shots.

Ultra-compact, Ultra-portable

The advanced tech comes without compromising ease-of-use. The RF mount provides outstanding image quality due to its compact design that boasts significantly increased communication speed and bandwidth between camera and lens compared to when using an EF mount lens and adapter.

Weighing just 570g, the RF 10-20mm f/4L IS STM deserves a permanent place in your kit bag. It’s less than half the weight (610g lighter) and 2cm smaller in width and length than the EF 11-24mm f/4L USM – in fact, the new lens paired with an EOS R8 weighs less than the older EF lens alone. Shooting with limited space becomes easier with the new IS technology and a wider angle of view, and your bag will be lighter, too.

Built for Professionals

Due to its superior image quality, greater capacity for wide-angle stills and video, and lightweight design, the RF 10-20mm f/4L IS STM is an essential upgrade for photographers and videographers looking to push their capabilities to the next level. While it’s ideal for capturing landscapes or architecture, the lens can also highlight different perspectives when shooting sports or documentaries. The RF 10-20mm f/4L IS STM is reliable in various weather conditions and is resistant to dust and moisture.

Key Features and Attributes Include:

• The aspherical, Super UD and UD lens elements (including one Aspherical UD element) help to achieve high image quality appropriate for an L lens

• Highly durable dust and water-resistant qualities to withstand rigorous conditions faced by professionals

• SWC (on 2 lens surfaces) and ASC (Air Sphere Coating) reducing ghosting caused by light sources within the image, a phenomenon often seen in wide-angle lenses

• First L series lens to feature STM motor and full-time manual focus capability, thanks to compact, lightweight focus group
