This lens is compatible with major camera brands including Canon RF, Sony E, Nikon Z and Fujifilm X Mount.

Sharp and colour-accurate images

The lens employs an advanced optical design with aspherical and low dispersion elements resulting in sharp, well-corrected, and colour-accurate images.

Advanced optical elements

The NiSi 15mm f/4 Lens employs optical glass including one double-sided aspherical element and two extra-low dispersion elements resulting in minimal distortion, minimal chromatic aberration, and vignetting.

Manual focus design with 112° angle of view

It features 112° angle of view with a manual focus design allowing the photographer to work with subjects as close as 20cm away.

Hard surface coating and anti-reflection technology

The lens uses anti-reflection technology to enhance light transmittance and minimise lens fare and stray light. NiSi’s hard surface coating technology improves the toughness and waterproofing of glass elements.

Create Compelling Sun Stars Effect

Its unique aperture design with 10 straight blades breaks the paradigm of needing a small aperture to create a Sunstar which allow you to capture Sunstars from f/4 to f/22 with optimal image quality throughout.
