Key Take-Aways:

The Mitakon Speedmaster 50mm f/0.95 III is a manual-focus full-frame normal prime with a record f/0.95 aperture, 10 elements in 7 groups, a metal barrel, a 67 mm filter thread, a 0.5 m minimum focus distance and a weight of 720 g, available for L-mount among other mounts, and Mitakon lists it at $799. As of Oct 2026, two written reviews and four videos are linked. Cameralabs (Thomas, tested on a Nikon Z7) finds the bokeh wide open second only to the Nikon Z 58mm f/0.95 S Noct and the corner light fall-off astonishingly low, but lists coma, astigmatism, spherical aberration, haloing, low flare resistance, strong focus breathing and no electronic contacts, so focusing wide open is harder than with sharper lenses; it still recommends it as by far the cheapest f/0.95 option for full frame. Alpha Shooters (Bernard Déry, on Sony E-mount) praises the stellar metal build, the long focus throw, the clickless aperture ring and the beautiful bokeh from 11 blades, finds centre sharpness excellent from f/2.8, and finds sharpness, contrast and chromatic aberration unimpressive at f/2.8 and wider, with distortion of about 1%. Of the videos, Richard Wong titles his “World’s First Review” and tested it on a Nikon Z6; Christopher Frost’s description of the Mark III update says the optics are essentially the same as the Mark II, with the same question marks over image quality but striking f/0.95 images; Manny Ortiz describes his video as putting the lens through its paces in the real world for portraits with high speed sync outdoors; and Frost’s later video checks the Nikon Z version.

From Mitakon:

Zhongyi Optics (ZY Optics) have released the new Mitakon Speedmaster 50mm f/0.95 version III for full frame L mount (Sigma FP, Panasonic S1 and S1H, Leica SL, SL2), Sony E, Nikon Z and Canon RF cameras.

Offering a natural 50mm perspective along with an ultra-fast f/0.95 maximum aperture, the Mitakon 50mm f/0.95 is a compact prime characterized by its bright f/0.95 aperture to suit working in low-light conditions. It also affords a great degree of control over depth-of-field for isolating subjects from the background and producing selective focus effects.

The new version III features a new optics design which offers a slightly more compact size and a better flare resistance. A carefully-designed 10 elements in 7 groups optics system with 1pc of HRI (High Refractive Index) & 5pcs of UD (Ultra-low dispersion) elements successfully minimizes the chromatic aberrations and delivers exceptional image quality.

An eleven-blade diaphragm helps to produce a softly diffused out-of-focus rendering (bokeh). The enclosure of the lens is made of metal to strengthen its durability.

Official Website

Mitakon publishes one set of figures for all mounts (Sony FE, Canon RF, Nikon Z and L Mount), so the weight of 720 g and the size of 73.3 mm by 83.5 mm (rounded to 84 mm) are not tied to L-mount; only the aperture blades differ, 11 blades and 9 for L-mount. The price is the regular $799 in Mitakon’s store, which currently shows $499 as a sale price.
