Brightin Star has introduced a revised version of its ultra-fast 50mm f/0.95 full-frame prime lens, expanding its range of manual-focus optics for mirrorless systems. The new 50mm f/0.95 Mark II retains the core concept of its predecessor—extreme low-light capability and a very shallow depth of field—while incorporating a redesigned exterior, an updated hood, and changes to its aperture mechanism.

The Mark II maintains the same optical formula used in the previous version, with 10 elements arranged in nine groups, including extra-low dispersion and ultra-high refractive index elements. The Chinese manufacturer states that the updated lens offers improved resolution and better resistance to flare, despite the stable element count. The aperture diaphragm now uses nine blades rather than the former ten-blade design, altering the rendering of out-of-focus areas. A new one-piece integrated hood has also been introduced, described as offering a more secure lock and improved control of stray light.

The lens remains a manual-focus design and has a minimum focusing distance of 0.5 meters, which aligns with typical limitations for optics of this type. Its weight, approximately 750 grams depending on the version, is unchanged from the earlier model. The dimensions are close to 72mm in diameter and 84mm in length, and the filter thread stays at 62mm.
