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

The NiSi 16mm f/2.8 ASPH. Ultra-Wide Medium Format Lens for Fujifilm G-Mount is a premium ultra-wide-angle prime designed to unlock the full potential of Fujifilm GFX medium format cameras. Delivering a full-frame equivalent focal length of approximately 12.6mm and an expansive 118°+ angle of view, this lens is ideal for capturing sweeping landscapes, dramatic architecture, expansive interiors, and immersive astrophotography with exceptional clarity and minimal distortion.

Purpose-built for modern 100MP medium format sensors, the lens features an advanced 16-element, 12-group optical design incorporating three precision-molded aspherical elements and four ultra-low dispersion (ED) elements. This sophisticated optical formula delivers outstanding sharpness from center to edge, excellent contrast, and true-to-life color while minimizing distortion across the entire image circle.

The fast f/2.8 maximum aperture provides excellent low-light performance, allowing photographers to shoot with lower ISO settings for cleaner night skies, astrophotography, and interior scenes. Advanced APO-level chromatic aberration correction effectively suppresses both axial and lateral color fringing, producing crisp edges and exceptional color accuracy even when shooting wide open.

Designed specifically for Fujifilm G-Mount, this version mounts directly to Fujifilm GFX medium format cameras without the need for an adapter. Its compact 108mm barrel length offers excellent balance and handling, making it comfortable to carry for landscape expeditions, architectural photography, and travel assignments.

The lens features an 8-blade diaphragm that produces beautifully defined 8-point sunstars from f/4 to f/22, adding dramatic starburst effects to sunsets, city lights, and nighttime scenes. A minimum focusing distance of just 0.25 meters enables creative close-up compositions with striking foreground emphasis and exaggerated ultra-wide perspective.

Constructed from durable all-metal materials, the lens incorporates a weather-sealing ring to help protect against dust and moisture in challenging outdoor environments. Despite its robust build, it remains lightweight at approximately 835g, making it an ideal companion for professional fieldwork. An 82mm front filter thread accepts standard screw-in filters, while NiSi's advanced SA+ anti-reflection and ultra-hard coatings reduce flare, improve contrast, and provide long-lasting protection against scratches, water, oil, and dirt.

Whether you're photographing breathtaking landscapes, modern architecture, interiors, or the night sky, the NiSi 16mm f/2.8 ASPH. Ultra-Wide Medium Format Lens delivers the optical precision, resolution, and creative perspective demanded by today's professional medium format photographers.

Product Features in Detail

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.

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.

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.

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.

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.

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

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.

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.
