RF10-20mm F4 L IS STM Lens
- RF ultra-wide-angle lens for full-frame cameras
- Incredible 10-20mm coverage for stills and video
- Excellent image quality with 1 super UD lens, 3 UD lenses, 3 aspheric lenses
- Subwavelength structure coating (SWC) and Air Sphere Coating (ASC) to reduce ghosting
- Minimum focus distance of approx. 9.8 in./0.25m with a maximum magnification of 0.12x
- Canon leadscrew-type STM (stepping motor) focus drive for smooth, quiet video AF operation
- Optical image stabilization up to 5.0 stops of shake correction and up to 6.0 stops Coordinated IS when paired with EOS R series cameras featuring In-Body Image Stabilizer (IBIS)
- Rear slot for pre-cut gel filters
- Petal-type hood integrated into the lens barrel
The RF10-20mm F4 L IS STM is a unique ultra-wide-angle lens that gives you corrected, rectilinear coverage to an incredible 10mm with full-frame cameras. Great for still photography and videography, the 10mm ultra-wide-angle effect is outstanding for its dramatic look, lending visual drama to your landscape, interior, architecture, travel, and even photojournalism images. This lens features true L-Series quality with optical and digital corrections for distortion, and optical image stabilization (OIS) for better low-light performance, especially when shooting video. Autofocus is handled by a tried-and-true STM-type focus motor which actually allows the overall lens design to be more compact while still providing rapid AF and smooth focusing during video recording.
Modern Design
The design of this lens is geared toward getting the job done efficiently with light weight, fast focusing, image stabilization, and a programmable control ring. There is even a petal-type lens hood built right into the barrel of the lens.
Incredible Dimensions
Capturing images at 10mm is already pretty special, but to do it in a lens that is lighter and smaller than even our own EF11-24mm f/4 L USM is quite a feat. The RF mount design allows for the possibility of this wider-angle lens range and is also a key factor in the size and weight reduction of the lens. This also enables the addition of IS (image stabilization) in a lens that otherwise might not be able to have it.
Excellent Image Quality
Again, thanks to the Canon RF lens mount, the RF10-20mm F4 L IS STM lens offers great optical quality. Its optical design includes one super UD element, three UD elements and three aspheric elements (including large-diameter aspheric and UD aspheric elements) as well as Subwavelength structure coating (SWC) and Air Sphere Coating (ASC) to reduce ghosting. On top of that, this lens features the same dust- and water- resistance found on L-series lenses with seals around the Control ring, focus ring, zoom ring, operation panel, and lens mount.
Make Some Movies
The RF10-20mm F4 L IS STM lens has a lot of advantages and features when it comes to video. First, you can take full advantage of the 10mm focal length on full-frame cameras, and you can even shoot 4K 60p without crop mode. If you are shooting on an APS-C camera, you’ll have access to wider angles than you ever have before (coverage equivalent to a 16-32mm lens). Another video advantage is the fixed f/4 aperture, minimizing exposure changes while zooming.
