Lens Overview — Mitakon Zhongyi 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.

Key Features — Mitakon Zhongyi 50mm f/0.95 Mark III

f/0.95 Maximum Aperture: One of the widest apertures available on a 50mm prime, enabling shooting in near-darkness and producing an extremely shallow depth of field.

Full-Frame Coverage: Designed for full-frame mirrorless sensors, delivering a natural 50mm field of view without any crop factor.

Four Mount Options: Available in Sony E, Canon RF, Nikon Z, and Leica M mounts, making it accessible across the major mirrorless platforms.

Manual Focus Only: No autofocus mechanism is present, giving photographers deliberate, tactile control over focus — particularly useful at f/0.95 where depth of field is razor thin.

Third-Generation Design: The Mark III represents Mitakon's latest iteration of the Speedmaster 50mm, refining optical and mechanical performance over previous versions.

67mm Filter Thread: A practical and widely available filter size for a lens of this aperture class, keeping filter costs reasonable.

Description — Mitakon Zhongyi 50mm f/0.95 Mark III

The Mitakon Zhongyi Speedmaster 50mm f/0.95 Mark III is an ultra-fast 50mm full-frame prime lens engineered for mirrorless shooters who demand maximum light-gathering capability. With a maximum aperture of f/0.95, this lens opens wider than almost any other commercially available prime, making it a compelling tool for photographers working in challenging lighting or pursuing extreme subject isolation. It is available in Sony E, Canon RF, Nikon Z, and Leica M mounts, covering the most popular full-frame mirrorless platforms.

The lens is manual focus only, with no autofocus system — a deliberate design choice that suits the careful, precise shooting style that f/0.95 demands. Its 67mm filter thread accepts standard accessories, and the 720g weight reflects the substantial optical construction required to achieve this aperture in a full-frame-covering design. No image stabilization is included, so in-body stabilization or steady technique will be important. As a standard focal length prime, it covers a versatile range of photographic applications from environmental portraits to low-light documentary work.
