  • Lens Function button

    Positioned in just the right place is a programmable function. Set it up in your EOS’s menu.

  • Portable design

    At 570g, the RF 10-20mm F4L IS STM can earn a permanent place in your bag, so you can enjoy an ultrawide viewpoint in more places more often.

  • Lens control ring

    Assign this instinctive control ring to change shutter speed, aperture, ISO, white balance or exposure compensation.

  • Built to perform

    Robust L-series construction is resistant to dust and moisture, while a fluorine coating and built-in lens hood protect the front element.

How you could use yours

  • Landscape

    Include more foreground detail for powerful compositions.

  • Architecture

    Show buildings in context by putting more into the frame.

  • Sports

    Take an unusual view and stand out from the crowd.

  • Astrophotography

    Shoot even more expansive views of the night sky.

  • Interiors

    Put more in the frame, especially in tight spaces.

  • Photojournalism

    Get close and shoot wide for powerful, immersive images.

  • Filmmaking

    Go even wider with establishing shots and point-of-view footage.

    • 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 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.

    CREATIVE TECHNIQUE

    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.

    DESIGN BRIEFING

    Ultrawide, ultra-portable

    The advanced nature of the RF lens mount allowed us to design the most portable AF ultrawide ever, without compromising on quality or performance. At just 570g, it weighs 610g less than our EF 11-24mm f4L USM lens, despite offering a wider angle of view and an optical Image Stabilizer.

    Steady and stable

    Ultrawide 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.2

    CANON QUALITY

    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.

    AUTOFOCUS

    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.

    L-SERIES QUALITY

    Built for the pros

    Even in the most challenging conditions, the RF 10-20mm F4L IS STM shines. Its weather resistant L series construction satisfies the demands of professionals and ensures this lens will last for years.
