NiSi 16mm f/2.8 ASPH. Ultra-Wide Medium Format Lens (Fujifilm G-Mount)

The NiSi 16mm f/2.8 ASPH. is an ultra-wide-angle prime built specifically for medium format mirrorless cameras. Designed for the Fujifilm GFX (G-Mount) system, it pairs a bright f/2.8 aperture with an expansive field of view exceeding 118 degrees and resolving power matched to 100-megapixel sensors. With a 12-group, 16-element optical design and a weather-sealed metal body, it brings true ultra-wide coverage and professional image quality to landscape, architecture, interior, and astro work in a compact, travel-friendly package.

This Fujifilm GFX (G-Mount) version mounts natively to Fujifilm GFX medium format bodies with no adapter required. It brings genuine ultra-wide coverage to a system that has long lacked an affordable, fast wide prime, unlocking sweeping landscapes, tight interiors, and night-sky work for high-resolution shooters who want maximum angle without compromise.

16mm Ultra-Wide Coverage

With a full-frame equivalent focal length of approximately 12.6mm, the NiSi 16mm f/2.8 delivers an ultra-wide field of view exceeding 118 degrees. That sweeping angle captures vast scenes, expansive skies, and exaggerated foreground perspective that longer lenses simply cannot reach, making it a natural choice for grand vistas and confined interior spaces alike.

Advanced Optical Design

A 12-group, 16-element optical formula includes three glass aspherical elements and four ultra-low dispersion elements. Together they suppress distortion, control aberrations, and keep lines straight even at the edges, delivering excellent image quality and resolving power across the large medium format image circle for architecture and symmetrical compositions.

Resolving Power for 100-Megapixel Sensors

The optical design delivers outstanding resolution from center to edge across the entire image circle, perfectly matched to high-resolution medium format cameras. Fine textures, distant detail, and subtle tonal transitions are rendered cleanly on today's 100MP sensors, with peak performance reached around f/5.6 for the most demanding studio and landscape work.

Stays Sharp Wide Open at f/2.8

Even wide open at f/2.8, the NiSi 16mm f/2.8 holds sharp detail from the center to the edge. Three aspherical elements help control coma, rendering point light sources cleanly, which makes it a strong performer for Milky Way and astrophotography. The bright aperture also lets you shoot at lower ISO for cleaner, less noisy night-sky frames.

Minimal Chromatic Aberration

The lens delivers APO-level control of chromatic aberration across the entire image circle. Axial and lateral colour fringing is kept to a minimum even wide open, resulting in clean edge definition and true-to-life colour in high-contrast scenes such as backlit horizons, city lights, and bright winter skies, so files need less correction in post.

Clean 8-Point Sunstars and Close Focus

A specially designed 8-blade aperture produces clean, defined 8-point sunstars from f/4 to f/22, balancing image quality with a strong starburst effect and a small, tidy center spot. A close 0.25m minimum focusing distance and 0.12x magnification let you push in on foreground subjects for added depth, scale, and dramatic wide-angle storytelling.

Precision Handling and Durable Build

The manual focus ring moves smoothly across a 180-degree rotation, while the clicked aperture ring gives accurate, tactile stop control. A weather-sealed metal body, cinema-inspired painted markings, SA+ anti-reflection coating, and an ultra-hard surface coating that resists water, oil, and fingerprints round out a lens built for serious, repeatable work in tough conditions.

Whether you are capturing the Milky Way, expansive landscapes, or dramatic architecture, the NiSi 16mm f/2.8 ASPH. delivers a rare combination of ultra-wide coverage, a bright f/2.8 aperture, and ultra-high resolution. Its 82mm filter thread also pairs with the JetMag Pro 95MAG magnetic system using a dedicated adapter. Built for the Fujifilm GFX (G-Mount) medium format system, it stands among the highest image quality ultra-wide medium format lenses available today, ready for ambitious work in the studio and the field.
