Design & Specifications
The MF 8mm F2.4 is a fully manual-focus circular fisheye engineered for medium-format sensors. Its 8mm focal length (roughly 6mm full-frame equivalent) combines with a 220° angle of view to wrap the entire surroundings into a single circular image – a look that ordinary wide-angle lenses cannot reproduce.
The optical design consists of 10 elements in 8 groups, including 2 high-refractive-index and 2 ED elements to control chromatic aberration across the huge image circle. The aperture range is F2.4 to F16 with a 10-blade diaphragm, and the minimum focusing distance is just 0.1m for bold, close-in compositions.
The all-metal body measures about Φ80 × 62mm (GFX) and Φ80 × 65mm (XCD), weighing approximately 511g and 536g respectively. As is typical of fisheye optics, a front filter thread is not supported.
A Perspective Beyond 180°
Unlike a standard 180° fisheye, the extra reach to 220° pulls in the space behind and around the camera, giving landscapes, architecture, interiors and night skies a distinctive spherical character. Combined with the 0.1m minimum focus, creatives can exaggerate foreground subjects while still capturing the full scene around them.
