7Artisans 10mm F2.8 II Fisheye (Nikon Z)

Coverage of the Mark II is mostly launch reporting rather than lab testing. What has been published points to a sharper centre and better edge rendering than the Mark I, helped by the new aspherical and ED elements, with tidy 10-point sunstars when stopped down.

The trade-offs are the same as before: manual focus and aperture only, no electronic contacts, no front filters, and corner softness and vignetting at f/2.8 that clear up by f/5.6 to f/8. It costs slightly more than the Mark I and is bigger, so owners of the original have less reason to upgrade than new buyers.

Early owners praise the solid metal build, smooth focus ring, very close focus and the extra-wide 185-degree view for skate, street and creative close-ups. The stepless aperture ring and glow-in-the-dark markings are popular for night and video work.

Complaints include the weight for a 10mm lens, the fixed hood that rules out filters, the lack of EXIF data and occasional flare from bright light just outside the frame.
