7artisans 12mm f 2 8 ii vs samyang af 12mm f 2?

The Samyang AF 12mm f/2 is the one I'd pick for most people. It autofocuses, and at f/2 it gives about the background blur of f/3 on Sony E or Fujifilm X. It fits Sony E, Fujifilm X and Canon RF.

The 7Artisans 12mm f/2.8 II is manual focus only, with no stabilisation, and it's slower at f/2.8. Its advantage is mount range: it also fits Nikon Z and Micro Four Thirds, which the Samyang doesn't. If you shoot Nikon Z or Micro Four Thirds, or you enjoy focusing by hand, it's a sensible choice.

Both are wide, so they suit landscapes, interiors and street scenes. For how the f-number changes depth of field across sensor sizes, see the focal length converter.
