Characterized by its ultrawide field of view, the black Leica L-mount NiSi 15mm f/4 Sunstar ASPH Lens is also distinguished by its distinct rendering of point light sources. Well-suited for landscapes, cityscapes, architecture, and interior applications, this ultrawide-angle prime strays from the norm with a 10 straight-bladed aperture design that promotes making clear 10-point sun stars from specular highlights throughout the aperture range. Optically, this lens sports a double-sided aspherical element and a pair of low dispersion glass elements, which help control a variety of aberrations and distortion for high sharpness, clarity, and accurate rendering. Both antireflective and protective coatings are featured, and the lens has a manual focus design with a 7.9" minimum focusing distance for working with close-up subjects.
- L-Mount Lens/Full-Frame Format
- Aperture Range: f/4 to f/22

NiSi 15mm f/4 ASPH Reviews
Beyond Expectations
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.
Great for sunstar
This is the lens for you if you like to get a clean Sunstar, IQ/build quality are pretty good too. The only low side is not aperture info. in photo information due to no electronic contact on lens, however, you still have exposure time and ISO. I believe it is good for nightscape photograph too.
Awesome for Sunstar
Purchased this manual lens recently, use hyperfocal on lens makes focus quiet easy. IQ is pretty good too. Light weight to carry around. The only low side is no F data cause of no electronic communication between lens and camera body, however, you still get ISO and exposure time on file. To avoid flare occurring when pointing directly to sun, you have to adjust the angle to get a good result. Recommend it if you like shooting sunstar.
