Canon RF Mount. This ultra-wide angle lens was designed for use on Canon RF-mount cameras. The large 65mm image circle easily covers any full-frame sensor without vignetting. You can also use it on APS-C cameras, on which it’ll provide a 32mm-equivalent focal length.

Shift and Rotation Functions. The Venus Optics Laowa 20mm f/4 Zero-D Shift for Canon RF has an extremely broad 94.4° angle of view that’s complemented by an impressive +/- 11mm shift range that helps compensate for converging lines and eliminate keystone distortion. The shift control works in combination with a 360° rotation mechanism that allows you to apply the shift in a range of directions to best suit shooting in horizontal and vertical orientations. The rotation mechanism has click stops at 15° increments for intuitive handling.

High-Quality Optics. This lens’s rectilinear optical design keeps distortion at bay, making it perfect for architectural, interior, and landscape photography. Its eleven-group/sixteen-element design includes two aspherical elements and three extra-low dispersion elements that help to eliminate chromatic aberrations and color fringing while keeping images sharp. An updated anti-reflective coating reduces flare and ghosting for greater contrast and color accuracy when you’re shooting in strong lighting conditions.

Fully Manual Lens. The 20mm f/4 is a fully manual lens. Its floating optical system maintains a high level of performance throughout its focal range of 9.8 inches to infinity, and its 14-blade diaphragm produces smooth circular bokeh and specular highlights when stopped down and capturing point light sources.

Shift Lens Support Compatible. This lens is compatible with the Venus Optics Laowa Shift Lens Support V2, which is available as a separate rental item. It gives you improved mounting and makes it easier to shoot shift-type stitched panorama photos without parallax errors.
