## Summary description

7Artisans 7.5mm F2.8 Mark II is a wide fish-eye lens designed for mirrorless interchangeable-lens cameras (MILC). It features an optical construction of 11 elements in 9 groups, a metal body, bayonet mounting and a 265 g weight. The lens delivers extreme wide-angle perspective suitable for creative landscape, architecture, cityscape and action photography.

## Long description

7Artisans 7.5mm F2.8 Mark II is an ultra-wide fish-eye lens for mirrorless interchangeable-lens cameras (MILC). The second generation introduces an optimized optical layout with 11 elements in 9 groups, including a higher-refractive-index front element and HOYA ED glass in the rear group to reduce chromatic aberration. The optical length is shortened compared with the previous generation, producing a more compact all-metal body that weighs 265 g. The lens provides an extreme wide-angle perspective suited to creative landscape, architecture, cityscape and action photography while maintaining improved image quality and mechanical durability.
Advantages
The updated optical design reduces chromatic aberration and improves sharpness across the frame while keeping the total element count at 11. A compact optical length and precise polishing contribute to better image rendering and lower distortion for a fisheye of this angle. The full-metal construction with an oxidized finish and a tungsten-colored electroplated bayonet increases corrosion resistance and mechanical stability. Added mount compatibility (including Nikon Z) expands system choice for MILC users.
Suitable for
Creative wide-angle landscape and night-sky photography
Architectural and interior shots with dramatic perspective
Cityscape and street scenes requiring expansive field of view
Action and sports where an extreme angle captures subject context
Artistic and experimental photography using fisheye distortion
Key specifications
Focal length: 7.5 mm (fisheye)
Maximum aperture: f/2.8
Optical construction: 11 elements in 9 groups
Special elements: high-refractive-index front element, HOYA ED glass in rear group
Mount type: bayonet mount for mirrorless cameras (including Nikon Z option)
Body material: metal with oxidized finish and electroplated mount
Weight: 265 g
Color: black
Filter/hood: no front filter holder or detachable hood due to large field of view
How to use
Attach the lens to a compatible MILC body by aligning the bayonet and mounting until it locks. Compose using the viewfinder or live view to include the extremely wide field of view; be mindful of the pronounced fisheye distortion near frame edges. Use wide apertures for low-light or creative shallow-depth effects and stop down to increase overall sharpness. Because there is no front filter holder, consider using rear-mounted or in-camera filter solutions when required. Store and transport the lens in a padded bag to protect the metal finish and optics.
Usage recommendations
For best results, shoot with careful composition to take advantage of the exaggerated perspective and maintain subject placement away from extreme frame edges where chromatic or geometric effects are strongest. When shooting landscapes or architecture, use smaller apertures to increase depth of field and bracket exposures for high-dynamic-range scenes. Regularly clean the front and rear elements with appropriate tools and avoid forceful contact with the metal mount to preserve the oxidized finish.
