NiSi Lens 15mm F4 Nikon Z-Mount

NiSi Lens 15mm F4 Nikon Z-Mount – Ultra-wide 112° field of view for creative landscapes and astrophotography

Lightweight ultra-wide lens built for mirrorless Nikon Z cameras

This NiSi 15mm F4 Nikon Z-mount lens weighs 470 grams and fits mirrorless cameras. Because it remains lightweight and portable, you can carry it for long shoots and travel without adding unnecessary bulk. As a result, it suits many photography styles, from nature and astrophotography to street, action, and creative portrait work that benefits from an ultra-wide look.

Extremely wide field of view and focal equivalence

The lens delivers an impressive 112° field of view. In practical terms, that wide coverage is equivalent to a 14.5mm focal length, giving you more scene in each frame compared with a typical 15mm angle of view. Therefore, you can capture expansive landscapes, dramatic foregrounds, and sweeping night skies with ease.

Durable metal housing and smooth manual focus

NiSi built the lens with an all-metal construction to provide durability and extra protection in demanding conditions. In addition, the focus ring uses a ball bearing for smooth, reliable operation. Consequently, you get comfortable and accurate manual focus adjustments, which helps when composing close foreground elements or pinpointing stars.

Anti-reflection finishes and filter compatibility

Both the front and rear surfaces feature matte paint anti-reflection treatment to reduce glare and stray reflections. Furthermore, the front of the lens accepts standard 72 mm circular filters and supports NiSi’s popular 100 mm filter holder systems. Thus, you can experiment with filters — such as graduated or ND filters — while keeping workflow simple.

Advanced optical construction for controlled aberrations

The optical design consists of 12 elements arranged in 10 groups. It includes one double-sided aspherical element and two extra-low dispersion elements. Because of this layout and the lens coatings, the design minimizes chromatic aberration, distortion, and vignetting, yielding cleaner images across the frame.

Coatings, aperture and creative starburst effects

The lens uses anti-reflection film technology to improve light transmission and reduce lens flare and stray light. In addition, its ten straight aperture blades produce distinct starbursts from f/4 to f/22. Notably, the starbursts remain free from glare due to the optical construction, so you do not need to stop down to very small apertures to create clean star effects.

Close focusing for dramatic foregrounds

With a minimum focusing distance of 0.2 m, this lens lets you place close foreground subjects dramatically within ultra-wide compositions. As a result, you can emphasize nearby elements while still capturing expansive backgrounds for strong visual impact.

Frequently Asked Questions

Question: Is this lens suitable for astrophotography?
Answer: Yes. The ultra-wide 112° field of view and the ability to produce clean starbursts from f/4 to f/22 make it well suited for night sky work, while the optical design minimizes flare and aberrations that can degrade star detail.

Question: Can I use standard screw-on filters with this lens?
Answer: Yes. The lens accepts standard 72 mm circular filters and also supports NiSi’s 100 mm filter holder systems, so you can use both screw-on and holder-based filters depending on your needs.

Question: How close can I focus to subjects with this lens?
Answer: The lens focuses down to 0.2 m, enabling dramatic close-foreground compositions while still capturing a wide background scene.

Question: Is the lens durable enough for outdoor use?
Answer: The lens features an all-metal housing and matte anti-reflection finishes on the front and rear, which together provide robust construction and reduced glare for outdoor and demanding shooting conditions.
