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

Canon redefines ultra wide-angle photography with the RF 10-20mm f/4L IS STM Lens. It offers unmatched performance and image quality down to 10mm.

This lens features a Peripheral Coordinated Control Image Stabiliser effective even in the corners, providing five stops of shake protection (six stops when used with EOS cameras with in-body stabilisation). With an expansive 130˚ angle of view, it's the widest AF zoom for full-frame cameras, that enables you to capture 16% more in the frame compared to a 12mm lens.

Advanced optics produce distortion-free, sharp images across the entire frame, maintaining straight lines even at the edges. The constant f/4 aperture ensures consistent exposures throughout the zoom range. It is ideal for landscape and architectural photographers aiming to enhance foreground details in tight spaces, but also appeals to filmmakers seeking impactful establishing angles as well as documentary and sports photographers who want to differentiate their work.

  • Full-Frame | f/4 to f/22
  • High-Speed STM Autofocus System
  • Optical Image Stabiliser
  • Programable Control Ring
  • One Super UD and Three UD Elements
  • Air Sphere and SWC Coatings
  • Weather-Sealed Construction

It's the perfect tool to achieve remarkable clarity and image quality, setting new standards in ultra wide-angle photography.

Drive some drama into your photography and filmmaking – simply superb for landscapes, architecture and interiors.

Broaden your creative horizons

See the world at 10mm

The RF 10-20mm f/4L 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 f/4L IS STM takes this to the next level – get in close and shoot ultra-wide for a dramatically different view of the world.

Ultra-wide, ultra-portable

The advanced nature of the RF lens mount allowed us to design the most portable AF ultra-wide ever, without compromising on quality or performance. At just 570g, it weighs 610g less than our EF 11-24mm f/4L USM lens, despite offering a wider angle of view and an optical Image Stabiliser.

Steady and stable

Ultra-wide 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.

Smooth and quiet focusing

Optimised STM autofocus delivers a professional performance – focusing quickly and accurately in virtual silence. Filmmakers will love its smooth video focusing.

Built for the pros

Even in the most challenging conditions, the RF 10-20mm f/4L IS STM shines. Its weather resistant L series construction satisfies the demands of professionals and ensures this lens will last for years.
