Overview

The Brightin Star MF 50mm F0.95 II is a manual focus full frame standard prime for Sony E, Nikon Z, Canon RF and Leica L mount. With its F0.95 maximum aperture it is among the fastest lenses in the 50mm class that are offered for these mounts. The "II" refers to the second version of the design, which was officially announced in China in December 2024 and reached wider sales in November 2025.

Optical design

The manufacturer manual lists 10 elements in 9 groups, an F0.95 to F16 aperture range and an angle of view of 43.8 degrees. The design includes two ultra low dispersion and four ultra high refractive index elements. The closest focusing distance is 0.5 m.

Focusing and handling

Focusing is manual with a focus ring and a clicked aperture ring. The II version has glow in the dark focusing and aperture scales. The lens has a built in telescoping hood and an all metal barrel. There are no electronic contacts, which means no aperture or focus data in the image files. Focus peaking or magnification is advisable at F0.95.

Build and size

The lens measures 72 mm in diameter and 84 mm in length and weighs 757 g. The filter thread is 62 mm. The weight is typical for a full frame f/0.95 lens, and it suits mirrorless bodies like the Sony A7 series or the Nikon Z6 and Z7 lines.

Where it fits

In the database the Mitakon Zhongyi Speedmaster 50mm f/0.95 III covers the same four mounts, and the TTArtisan 50mm f/0.95 is a lighter APS-C focused option for several mounts. For a more moderate aperture there are the TTArtisan 50mm f/1.2 and the 7artisans Photoelectric 50mm f/1.05. Autofocus alternatives such as the Sony FE 50mm F1.2 GM or Nikon Nikkor Z 50mm F1.2 S belong to a different price class.
