Brightin Star has announced the MF 14mm f/2.8, a manual-focus ultra-wide-angle lens for full-frame mirrorless cameras, available in Sony E, Nikon Z, Leica L, and Canon RF mounts. The lens covers a 116-degree angle of view and is aimed at landscape, architectural, interior, and astrophotography applications.

The optical formula comprises 13 elements in nine groups, incorporating two aspherical elements, five high-refractive-index elements, and three extra-low-dispersion elements. The maximum aperture is f/2.8, stopping down to f/22 through a 10-blade diaphragm that produces 10-point starburst effects around bright point light sources when closed down — a characteristic relevant to both night sky and urban photography. Minimum focusing distance is 20 centimeters, enabling close foreground placement within the wide field of view.

The front filter thread is 82mm and is designed to accept square ND and CPL filter holders, which the Chinese company states can also function as a lens hood — an arrangement that avoids the need for a separate hood while retaining front filter compatibility, an approach that addresses the common difficulty of using screw-in filters on recessed ultra-wide lenses. A multi-layer Star Nano IMC coating is applied to the elements, intended to reduce flare and ghosting and maintain color accuracy under conditions involving bright or off-axis light sources. At 14mm, this coating behavior is particularly relevant to astrophotography and shooting toward artificial light sources in urban environments.
