Brightin Star has released the MF 11mm f/2.8 II, an updated version of its full-frame fisheye lens that introduces changes to both optical construction and external design while maintaining the core characteristics of the original model. The lens retains an extreme 182-degree angle of view, producing pronounced distortion and a curved perspective typical of fisheye optics, allowing a large portion of a scene to be captured within a single frame, making it suitable for applications such as landscape, architectural, and experimental photography.

The lens has an aperture range of f/2.8 to f/22 and uses an eight-blade diaphragm, and its optical structure consists of 11 elements arranged in eight groups, including specialized elements and updated coatings intended to reduce flare and improve contrast.

The construction is based on an aluminum alloy body, with a total weight of approximately 550 grams. The lens remains fully manual, with a focus ring and a stepless aperture ring that allows continuous adjustment of exposure, which may be relevant for video use. A rear focusing system is employed, meaning the physical length of the lens does not change during focusing.

The minimum focusing distance is approximately 0.17 meters, allowing subjects to be placed very close to the front element, thus enabling exaggerated perspective effects, particularly when combining near foreground elements with a wide background.
