Review Summary

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.

Where professional photography meets superior technology, the NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens emerges as a top choice for photographers seeking to capture stunning landscapes, seascapes, night scenes, architecture, interiors, and natural beauty. This lens boasts an ultra-wide 112-degree field of view, expertly paired with an advanced optical design that includes aspherical and low dispersion elements. This combination ensures sharp, color-accurate images that are well-corrected for optimal visual impact.
Designed for manual focus, this lens allows photographers to work with subjects as close as 0.2m/7.87" away, creating striking close-up foreground subjects. The lens elements, crafted from high-quality optical glass, include one double-sided aspherical element and two extra-low dispersion elements. This design minimizes chromatic aberration, distortion, and vignetting, enhancing the overall image quality.
The NiSi 15mm f/4 Sunstar lens utilizes anti-reflection technology to improve light transmittance and reduce lens flare and stray light, ensuring every shot is clear and vibrant. The lens also features NiSi's hard surface coating technology, which enhances the toughness and waterproofing of the glass elements, making it a durable choice for photographers.
One of the standout features of this lens is its ability to create a stunning Sunstar effect when including a light source in the frame. This, combined with the lens's compact form factor that supports standard 72mm circular filters and 100mm filter holder systems, allows photographers to experiment with and enjoy the use of filters with ease.
Designed for full-frame Leica L-mount mirrorless cameras, this super-wide prime lens can also be used with APS-C models, where it provides a 22mm equivalent focal length. The NiSi 15mm f/4 Sunstar Super Wide Angle Full Frame ASPH Lens is a versatile, high-quality addition to any photographer's toolkit.
