  • Type

    Ultra-Wide Zoom

    Ultra-wide angle lenses with zoom capability and a shooting angle of approximately 180°. They have a strong distortion effect which is usually the desired effect. Their focal distance usually starts from 15-23mm in full frame, 8-15mm in crop frame, and 30-45mm in medium format.

  • Mount

    The type of mount that the camera body must have in order for the lens to be fully functional when attached to it.

    2. Some lenses can be used with older mounts from the same manufacturer, sacrificing certain functions (e.g. autofocus), or even with mounts from other manufacturers using an adapter.

  • Item

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

    Fixed Aperture Zoom

    Lenses with variable optical (zoom) that remain equally bright (same maximum aperture value) throughout the entire focal distance range they offer. Usually significantly more expensive than their variable aperture counterparts.

  • Sensor Type

    Full Frame

    Photographic lenses designed for use on full frame sensor cameras. A full frame lens can also be used on a crop frame sensor camera, but with its focal length adjusted according to the corresponding crop factor.

    For example, a full frame lens with a focal length of 50mm (standard) on a camera body with a crop factor of 1.6 will function with a perspective as if it were an 80mm lens (telephoto).

    The reverse does not work as the optics of a crop frame lens are not sufficient to cover an entire full frame sensor, resulting in the edges of the frame being black (severe vignetting).

  • Maximum Aperture (f)

    Opening the diaphragm determines the amount of light received by the camera and affects the depth of field.
    2. The most open aperture of a lens is called the maximum. The more open the aperture (smaller f-number), the shallower the depth of field.

Description

Description

The Canon RF 10-20mm F4L IS STM redefines ultra-wide zoom lenses for full-frame cameras, offering the widest angle of view of up to 130 degrees with autofocus. Featuring an exceptionally compact design and weighing just 570g, it incorporates optical image stabilisation, advanced Super UD and aspherical glass elements, and a quiet STM motor. It is the ultimate choice for architecture, landscapes, astrophotography and professional video productions.

Wider 130° Viewing Angle

The RF 10-20mm F4L IS STM offers a viewing angle of up to 130˚, capturing 16% more detail in the frame compared with a 12mm lens. It enables you to create immersive shots with a unique perspective, making it ideal for architecture, landscapes, astrophotography and interiors.

Extremely Portable & Lightweight Design

Thanks to the advantages of the RF mount, the lens weighs just 570g, making it 610g lighter than the older EF 11-24mm f/4L USM. Despite its low weight and compact size, it retains the premium build quality of the L-Series, with full protection against dust and water droplets.

Advanced IS Optical Stabilization

It features a built-in optical image stabilizer that provides up to 5.0 stops of shake correction (up to 6.0 stops when paired with EOS R bodies equipped with IBIS). In addition, the peripheral coordinated control algorithm reduces distortion in the corners of the frame when shooting video.

Superior Optical Quality & Coatings

The optical design includes Super UD elements, three UD elements and three aspherical glass elements to eliminate distortion and aberrations. In addition, the special SWC and ASC coatings minimise internal reflections, ghosting and flare.

Smooth & Quiet STM Focusing

The STM screw-type autofocus motor delivers fast, precise, and nearly silent performance. It is ideal for video recording, ensuring smooth focus transitions without distracting noise, while supporting 4K 60p recording with no crop.

Ergonomics & Close Focusing

It features a programmable lens function button, a Control Ring, and a built-in petal-type lens hood. With a minimum focusing distance of less than 10 inches, it lets you capture stunning close-ups with a strong sense of depth in the background.
