Crop-Frame Canon RF-Mount Cine Lens. The Mitakon SpeedMaster 35mm T1.0 for Canon RF belongs to Canon’s line of RF-mount lenses. It’s compatible with Canon RF cameras. It does not work with Canon EF-mount cameras.

Ultra-Fast Aperture Cine Prime. The ultra-fast T1 aperture provides flexibility to shoot in even the lowest of light. It also enables paper-thin depth of field for extreme subject/background isolation. The nine-blade diaphragm contributes to pleasing bokeh when you’re using the lens wide open.

High-Quality Optical Design. The eight-group/eleven-element optical formula ensures image sharpness and color accuracy at all apertures with minimal chromatic aberrations.

Consistent Cine Build. The 17mm, 25mm, and 35mm Mitakon SpeedMaster lenses have the same 80mm front diameters, 0.8 pitch gears, 77mm filter threads, and focus and iris ring positions. This allows for super-fast lens changes just by swinging your matte box and dropping your follow focus without moving their positions. Markings in feet appear on both sides of the lens, making it easy for ACs and focus-pullers to do their jobs.

Minimal Focus Breathing. The Mitakon SpeedMasters’ fully manual internal-focusing design keeps the front of the lens from rotating during focusing, minimizing focus breathing.

Fully Manual. This lens provides no electronic communication with the camera. You must make all aperture and focus adjustments manually on the lens itself. The aperture you select won’t be displayed on the camera.
