Canon rf s 7 8mm f 4 stm dual vs 7artisans 7 5mm f 2 8 fisheye ii?

Both are wide primes for APS-C, but they suit different people.

The Canon RF-S 7.8mm f/4 STM Dual is the one to pick if you shoot Canon RF and want autofocus. It's made for the R7 and for recording spatial video. It has no stabilisation and it's f/4, so it's not a low-light lens.

The 7Artisans 7.5mm f/2.8 Fisheye II is brighter, and it's manual focus only. It mounts on Sony E, Fujifilm X, Nikon Z, Canon RF and Micro Four Thirds, so it's the choice if you might switch systems or want that fisheye look.

For how the apertures compare in depth of field, see the focal length converter.
