NiSi Lens 15mm F4 Sony E-Mount

NiSi Lens 15mm F4 Sony E-Mount – 112° Ultra-Wide Field of View

This NiSi 15mm F4 lens for Sony E-mount delivers an expansive 112° field of view while remaining lightweight and portable. Weighing 470 grams, it pairs well with mirrorless cameras and travels easily for a wide range of photographic work.

Designed for multiple photography styles

Use this ultra-wide lens for nature and astrophotography, street and action photography, or creative portraits with a distinctive ultra-wide look. Because it is compact and light, you can carry it for extended shoots and switch between genres without extra bulk.

Ultra-wide optics and equivalent focal length

The lens offers a 112° field of view, which is wider than the typical angle expected from a standard 15mm. In fact, its angle of view is equivalent to a 14.5mm focal length, giving you a noticeably broader perspective for immersive compositions.

Durable, precision build

The barrel uses an all-metal construction to withstand challenging environments. Moreover, the focus ring runs on a ball bearing for smooth, precise adjustments. Both the front and rear of the lens feature matt paint to reduce reflections and help avoid glare on the exterior surfaces.

Optical construction and performance

The lens contains 12 elements in 10 groups. It includes one double-sided aspherical element and two extra-low dispersion elements to minimize chromatic aberration, distortion, and vignetting. In addition, the lens applies anti-reflection film technology to improve light transmittance and reduce lens flare and stray light.

Filters and front thread

The lens accepts standard 72 mm circular filters via its 72 mm front thread. It also supports NiSi’s 100 mm filter holder systems, allowing you to work with larger rectangular or square filters when needed. This flexibility makes it easier to experiment with graduated filters, neutral density filters, and other filter types.

Aperture, starbursts and creative effects

Featuring ten straight aperture blades, the lens can produce starburst effects across a wide aperture range. Specifically, it creates starbursts from f/4 to f/22. Thanks to the optical design, these starbursts form without unwanted glare, enabling you to achieve striking point-light effects without needing an extremely small aperture.

Close focusing capability

The minimum focus distance is 0.2 m, which helps you place a close foreground subject into the frame for dramatic wide-angle compositions. This close focusing opens up creative opportunities for emphasizing foreground detail while keeping expansive backgrounds.
