The lens is compatible with APS-C format mirrorless digital cameras and provides a 78 angle of view which translates into a 35mm format focal length equivalency of 22mm. The wide-angle of view is combined with an advanced optical design, which includes aspherical, and low dispersion elements, to achieve a well-corrected, sharp, and color-accurate image. The lens has a manual focus design and allows working with subjects as close as 0.2m/7.87” away.

The lens elements are made of optical glass and comprise of one double-sided aspherical element and two extra-low dispersion elements. It features minimal chromatic aberration, minimal distortion and vignetting. It utilizes anti-reflection technology in order to improve light transmittance and reduce lens flare and stray light. NiSi’s hard surface coating technology improves the toughness and waterproofing of glass elements.

The NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens has a minimum focal distance is 0.2m which creates stunning visual impact for close-up foreground subjects and looks great including a light source creating a Sunstar.

The compact form factor design supports standard 72mm circular filters and 100mm filter holder systems. This allows you to shoot while experimenting and enjoying the use of filters with ease using a compact system with a lens with a 112 field of view.

The NiSi 15mm f/4 is designed for full-frame but when mounted on a Fujifilm X mount mirrorless camera, APS-C models will have a 22mm equivalent focal length.
