As expected, NiSi Optics has announced the release of its first wide-angle lens, which was announced earlier this month. This is a Sunstar 15mm f / 4 lens and is offered with Canon RF, Nikon Z, Fujifilm X and Sony E mounts.
The optical design of a fully handheld metal construction lens consists of 12 elements in 10 groups, including one double-sided aspherical element and two extra-low dispersion elements. The ten-blade aperture, capable of taking values ​​in the range of f / 4-f / 22, allows you to turn point light sources in the frame into characteristic stars, which is reflected in the product name.
The field of view when mounted on full-frame cameras is 112 °. On APS-C cameras, the angle is 78 °. The minimum focusing distance is 20 cm. The lens is designed for 72 mm filters. Its largest diameter is 75.6 mm, length – 80.5 mm, weight – 470 g.
The lens is priced at $ 579.
