7artisans af 10mm f 2 8 vs ttartisan 10mm f 2 asph?

Both are 10mm primes for APS-C, and they frame almost the same. On Sony E, Fujifilm X or Nikon Z, each gives roughly a 15mm full-frame view. The real difference is focus and light.

The 7Artisans AF 10mm f/2.8 has autofocus. For most people, especially if you shoot anything that moves, that's the one I'd choose. The TTArtisan 10mm f/2 ASPH is manual focus, but it opens wider at f/2, so it lets in more light and gives more background blur. It also fits Canon RF and Micro Four Thirds, which the 7Artisans doesn't.

My pick: the 7Artisans if you want it to just work, and the TTArtisan if you don't mind focusing by hand or you shoot Canon or Micro Four Thirds. If you're unsure how much the aperture difference matters, the lenses guide explains what each stop does.
