NiSi Optics has announced the release of its very first lens, a 15mm F4 ‘Sunstar’ wide-angle lens for Canon RF, Fujifilm X, Nikon Z and Sony E mount cameras.

The fully-manual lens features an all-metal construction and is comprised of 12 elements in 10 groups, including one double-side aspherical element and two extra-low dispersion elements. It has an aperture range of F4 through F22 and uses a ten-blade aperture diaphragm, which helps to create the signature sunstars this lens is named after.

The angle of view is 112-degrees when mounted on full-frame cameras and 78-degrees when mounted on Fujifilm X mount cameras. Other features include a minimum focusing distance of 20cm (7.9”) and a 72mm front filter thread. The lens measures 75.6mm (3”) diameter, 80.5mm (3.2”) long and weighs 470g (1lb).

Below are a handful of sample images taken with the lens and provided by NiSi:
