Two extra-low dispersion elements control color fringing and chromatic aberrations for accurate colors and high clarity.
Antireflective coating minimizes lens flare and ghosting for improved contrast when working in strong lighting conditions.
Hard surface coating protects the front element from markings and also adds a water-resistant finish.
Manual focus design permits working with subjects as close as 7.9" away.
Distinct 10 straight-blade aperture design promotes making 10-point sun stars from specular highlights throughout the aperture range.

I just love it Thank you NISI
Sharp and good color

Received this lens in February and, as advertised, it makes very good sun stars at any aperture. The lens is sharp and the color good. The only major downside is presence of flare when shooting into the sun. Not unusual, but for a lens that features all-aperture sun stars a definite weakness. Carefully angling the lens when shooting into the sun usually helps avoid flare. Loss of contrast when shooting into the light, on the other hand, is not bad at all. Overall a pretty nice lens then, and definitely nice for the price.

Is the lens weather sealed at all?
No, the NiSi 15mm f/4 Sunstar ASPH Lens for Nikon Z (Black) is not a weatherproof lens. However, the front element has a water-resistant coating; this prevents the lens from marking.
