The AF 10mm f/2.5 Max Fisheye combines an unusually broad 185-degree view with autofocus and a bright aperture, though corner sharpness, flare and coma remain limitations.
7Artisans’ AF 10mm f/2.5 Max Fisheye arrives as an unusual and welcome addition to the full-frame mirrorless market. According to DPReview, the lens covers a 185-degree field of view, supports Sony E, Nikon Z and L mounts, weighs about 510g and carries a list price of $449. Phillip Reeve’s testing on a Nikon Z7II suggests it is also one of the few native autofocus fisheyes aimed at this segment, giving photographers a rare combination of extreme angle, automatic focusing and a relatively bright f/2.5 aperture.
The lens makes a strong first impression in the hand. Phillip Reeve reports an all-metal barrel, weather-sealing around the mount and a USB-C port for firmware updates. The design also includes a clicked aperture ring, an AF/MF switch and two customisable function buttons, one of which can store preset focus distances. That said, the aperture ring’s “A” setting has no lock, so it can be moved accidentally. Other independent coverage from Camera Times and Lens Arena broadly matches this picture, describing the lens as solidly built, compact for its class and fitted with an optical design of 11 elements in eight groups.
Optically, the lens performs better than its novelty factor might suggest. Reeve found that central sharpness is excellent wide open, with the mid-frame also very strong, while the extreme corners remain soft unless the lens is stopped down significantly. Close-up performance is notably impressive, staying very good to excellent through much of the aperture range before diffraction begins to soften the image. Camera Times reached a similar conclusion, highlighting strong central resolution but weaker edge performance and visible chromatic aberration towards the periphery.
The fisheye character is, of course, central to the appeal. The lens produces the expected heavy geometric distortion, although 7Artisans has released a correction profile for users who want a more conventional ultra-wide rendering. Reeve also measured substantial vignetting wide open, which declines as the aperture closes, while longitudinal chromatic aberration is well controlled and lateral fringing is present but easy to correct in post-processing. Independent reports from Tocatlian and other product summaries similarly note the supplied correction profile and the lens’s intended use as a full-frame fisheye rather than a rectilinear ultra-wide alternative.
The weaker points are also fairly clear. According to Reeve, flare resistance is only moderate once the lens is stopped down, with a noticeable ring-shaped artefact appearing when the sun sits near the frame centre. Coma is present in the outermost corners and is reduced only after stopping down to around f/8, which limits its appeal for astrophotography. Sunstars become more defined at smaller apertures, and focus breathing is modest, but neither is a headline feature. Even so, the overall verdict is positive: this is a distinctive lens with useful autofocus, a fast aperture and unusually broad coverage, even if it does not quite deliver perfection at the frame edges.
