Full-Frame Canon EF-Mount Cine Lens. The Mitakon SpeedMaster 50mm T1 for Canon EF is only compatible 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 six-group/twelve-element optical formula ensures image sharpness and color accuracy at all apertures with minimal chromatic aberrations.

Cine Build. This lens has a 114mm front diameter, 0.8 pitch gears, and a 112mm filter thread. 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 Zhongyi 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.
