Canon RF Mount. The Venus Optics Laowa 24mm f/14 Probe Lens for Canon RF belongs to Canon’s line of RF-mount lenses. It’s only compatible with Canon RF-mount cameras; it does not work with Canon EF-mount cameras.

Wide-Angle Macro Lens. The Venus Optics Laowa 24mm Probe Lens’s unique design gives you a larger-than-life 2:1 maximum magnification, a 1.5-foot minimum focusing distance, and a 0.8-inch working distance. As a wide-angle lens, it gives you greater depth of field than standard telephoto macros. This means you get less subject isolation and more background detail.

Virtually Distortion-Free. This lens’s rectilinear 19-group/27-element optical design keeps distortion at an absolute minimum. It includes two extra-low dispersion elements and one extra refractive index element, which help to eliminate chromatic aberrations, distortions, and color fringing. Additionally, there’s a built-in LED ring light at the front of the lens, which will help you focus at close distances.

Fully Manual Lens. This is a fully manual lens that provides no electronic communication with the camera. You must manually make all aperture and focus adjustments on the lens itself, and lens information is not transferred through EXIF data. A dedicated switch lets you quickly de-click the manual aperture ring for smooth, quiet rotation that’s great for video.
