Great Build Quality Lens with great Optics and Wonderful Sunstar Capabilities

After seeing several reviews for this lens I decided to take a chance and add it to my kit for my Lumix Full Frame S5. I?m glad I did. The build quality is excellent as well as the optics. Super sharp at all f-stops. The Sunstar effect at wide apertures is very impressive. Being such a wide angle, manual focusing is so easy. I like the positive click on the f-stop dial giving it smooth, nice feel. The weight is well balanced on my S5, like it was made for it The ability to add a 72mm filter is a nice advantage for my landscape work when I want to use a Polarizer or ND. On some VERY HIGH Contrast areas my RAW files had some Chromatic Aberration but nothing that couldn?t be fixed easily in Post (interesting my JPEG versions did not have it as much, barely there). Obviously this is a fully manual lens so it will slow down your shooting, which for me is not a big deal as I've been a photographer a very long time long before autofocus and auto exposures. Also it's not Weather Sealed so I will be careful in the types of environments I shoot with it. You can't beat the price especially for this type of quality. So overall I am very please with NISI an their first production lens and highly recommend it.

NiSi 15mm f/4 Sunstar Super Wide Angle Lens.

The NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens combines a compact form factor with a super ultra-wide field of view making it the perfect companion for landscape, seascape, night, architecture, interior and nature applications. The wide 112 Degree 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.

Unique Aperture Design.

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. This breaks the paradigm of requiring a small aperture to create a Sunstar.

Unique Aperture Design.

Minimal Chromatic Aberration.

The lens elements are made of optical glass and comprise 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. NiSifs hard surface coating technology improves the toughness and waterproofing of glass elements.

Minimal Chromatic Aberration. 

Stunning Visual Impact.

The NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens has a minimum focal distance of 0.2m which creates stunning visual impact for close-up foreground subjects and looks great including a light source creating a Sunstar.

The compact form factor design supports standard 72mm circular filters and 100mm filter holder systems. This allows you to shoot while experimenting and enjoying the use of filters with ease using a compact system with a lens with a 112 Degree field of view.

Minimal Chromatic Aberration.
