Premium filter and optical brand NiSi has officially announced its brand-new ultra-wide prime lens for the Fujifilm GFX medium format mirrorless system: the ‘NiSi 16mm f/2.8 ASPH.’ According to reports published by global camera specialty outlet FujiRumors, this release marks an optical milestone, resolving a long-standing void in medium format systems by delivering a fast, ultra-wide prime.
Combining a striking full-frame equivalent focal length of approximately 12.6mm with a bright f/2.8 aperture, here is a breakdown of the core specifications engineered to squeeze every ounce of micro-detail out of 100-megapixel sensors.
1. Equivalent to 12.6mm with a 118° Field of View... The Brightest Ultra-Wide Medium Format Prime
- 118-Degree Diagonal Field of View: Provides an expansive perspective equivalent to roughly 12.6mm on full-frame. It delivers a breathtaking sense of scale and distortion-free rendering for vast natural landscapes, tight indoor architecture, and grand real estate interiors.
- Bright F2.8 Maximum Aperture: Features a fast f/2.8 maximum aperture, among the brightest for non-distorting ultra-wide medium format optics. Capturing significantly more light than standard f/4 or f/4.5 lenses, it ensures clean, low-noise imagery for night sky astrophotography (Milky Way) and low-light environments.
2. Designed for 100-Megapixel (100MP) Sensors with APO-Level Aberration Control
- Advanced Optical Formula (16 Elements in 12 Groups): Incorporates 3 Aspherical (ASPH) elements and 4 Extra-low Dispersion (ED) elements to maintain razor-sharp resolution from center to extreme corners.
- Coma and Chromatic Aberration Suppression: Meticulously controls sagittal comatic flare (coma) so pinpoint stars retain their shape without distorting—a critical requirement for astrophotography. Furthermore, APO-tier (Apochromatic) axial and lateral chromatic aberration correction minimizes purple or green color fringing along high-contrast edges even wide open at f/2.8.
- SA+ Super Anti-Reflective Coating: Utilizes NiSi’s proprietary SA+ Super Broadband coating alongside a hard protective layer to eliminate flare and ghosting during backlit shooting.
3. Pro-Grade Mechanical Controls and Weather Sealing
- 180-Degree Focus Throw: Equipped with a precision manual focus (MF) ring featuring a long 180-degree rotation angle for pinpoint focus adjustments.
- Universal 82mm Front Filter Thread: Designed without a bulbous front element, allowing photographers to screw standard 82mm circular filters and ND/GND holder systems directly onto the barrel without needing cumbersome adapters.
- Durable Build and 835g Footprint: Features an all-metal mount and weather-sealing rings to protect against dust and moisture, keeping overall weight to an accessible 835g for high portability on field trips.
✍️ Editor's Note
"Seeing a fast f/2.8 aperture combined with a 12mm-equivalent ultra-wide focal length on a medium format system is genuinely exciting! Ultra-wide choices for GFX shooters have historically been limited or constrained by slower apertures (f/4.5 or slower). The new NiSi 16mm f/2.8 ASPH. isn't just about offering a wide field of view; it is a smart optical design built to resolve 100-megapixel sensors while offering APO-tier chromatic aberration control and coma suppression tailored for Milky Way shots. The inclusion of an 82mm front filter thread and a 180-degree manual focus throw proves NiSi built this lens with landscape and astrophotographers' workflows in mind. Offered at a competitive $1,499 launch price, this lens is sure to land on the wishlist of GFX creators planning to capture starry night skies and sweeping natural landscapes!"
