The wide 112° angle of view is combined with an advanced optical design, which includes aspherical, and low dispersion elements, to achieve a well-corrected, sharp, and colour-accurate image. The lens has a manual focus design and allows working with subjects as close as 0.2m/7.87′′ away. The NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens features a unique aperture design that contains 10 straight blades allowing for Sunstars from f/4 to f/22 and optimal image quality throughout.
