Mitakon Zhongyi Speedmaster 50mm f/0.95 Mark III

The Mitakon Zhongyi Speedmaster 50mm f/0.95 Mark III is a manual-focus prime lens designed for full-frame mirrorless systems, available in Sony E, Canon RF, Nikon Z, and Leica M mounts. Its headline specification is the maximum aperture of f/0.95, which places it in a rare category of ultra-fast standard primes capable of gathering an exceptional amount of light in low-light environments. As a 50mm prime, it sits squarely in the standard focal length range, making it a versatile choice for portraiture, street photography, and any situation demanding shallow depth of field or low-light capability.

The lens is manual focus only — there is no autofocus mechanism — which suits photographers who prefer deliberate, tactile control over their focus plane, particularly when working at such an extreme aperture where depth of field is razor thin. It accepts 67mm filters, a relatively moderate front thread size for a lens of this aperture class. Weighing 720g, it carries meaningful mass but remains manageable on compact mirrorless bodies.

No image stabilization is present, so steady shooting technique or in-body stabilization from the camera will matter. This Mark III iteration represents the third generation of Mitakon's flagship fast-fifty design.
