Characterized by its ultrawide field of view, the black Canon RF-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.

Ultrawide prime is designed for full-frame Canon RF-mount mirrorless cameras.
One double-sided aspherical element reduces distortion and spherical aberrations in order to achieve high sharpness and accurate rendering.
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.
