Canon RF 135mm F1.8 L IS USM camera lens

Bright F1.8 aperture for portrait depth

The Canon RF 135mm F1.8 L IS USM is a medium telephoto prime lens built for mirrorless RF-mount cameras. Its wide maximum aperture gives precise control over depth of field and smooth background separation. The optical design uses 17 elements in 12 groups, including three UD glass elements and Air Sphere Coating to reduce chromatic aberration and ghosting. This new lens suits photographers and videographers who need low-light capability and subject isolation.

RF mount with optical stabilisation built in

The lens mounts directly to Canon EOS R series mirrorless bodies and uses a Nano USM motor for fast, smooth and quiet autofocus during both stills and video. Optical Image Stabilisation provides up to 5.5 stops of shake correction on its own, extending to 8 stops when paired with a camera body featuring In-Body Image Stabiliser. Two programmable function buttons on the barrel allow quick access to focus controls without removing the eye from the viewfinder. Builders using non-RF systems or requiring zoom flexibility cannot use this lens.

Stabilised low-light shooting at 135mm

The combination of a bright F1.8 aperture and up to 5.5 stops of optical stabilisation enables handheld telephoto work in dim conditions without raising ISO excessively. Coordinated IS with compatible bodies pushes correction further for steadier video footage. Nano USM drive keeps focus adjustments quiet, useful when recording audio on-camera. Photographers needing wider angles, macro magnification or a variable focal length should consider other options.
