NiSi has released the Leica L-Mount version of the 15mm F4 Wide Angle Full-Frame ASPH Lens. Now the NiSi 15mm F4 Lens is available for mirror-less camera mounts including Sony E, Canon RF, Nikon Z, Fujifilm X and Leica L.


The NiSi 15mm F4 Lens combines a compact form factor with an ultra-wide field of view, making it the perfect companion for landscape, seascape, night, architecture, interior and nature applications. 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 color-accurate image. The lens has a manual focus design and allows working with subjects as close as 0.2m/7.87″ away.



The lens elements are made of optical glass and comprised of one double-sided aspherical element and two extra-low dispersion elements.  It features minimal chromatic aberration, minimal distortion and vignetting.  It utilizes anti-reflection technology in order to improve light transmittance and reduce lens flare and stray light. NiSi’s hard surface coating technology improves the toughness and waterproofing of glass elements.



The NiSi 15mm F4 Lens features a unique aperture design that contains 10 straight blades, allowing for Sunstars from F4 to F22 and optimal image quality throughout. This breaks the paradigm of requiring a small aperture to create a Sunstar.


The minimum focal distance of this lens is 0.2m, which creates stunning visual impact for close-up foreground subjects.



The lens also supports the standard 72mm circular filter and 100mm filter holder system, allowing you to easily experience and enjoy the use of filters while shooting.



The super-wide prime is designed for full-frame mirror-less cameras, but it can also be used with APS-C models where it provides a 22mm equivalent focal length.
