Is the 7artisans 9mm f 5 6 good on aps c?

Yes, it works well on APS-C. On Sony E, Nikon Z, or L-Mount bodies, the 9mm frames like a 14mm lens on full frame, and f/5.6 gives about the depth of field of f/8.4. On Canon RF APS-C it's similar, with f/9 depth of field. That deep focus suits landscapes, architecture, and street shots where you want most of the scene sharp.

It's manual focus only and not stabilised, so it's a lens for slower, deliberate shooting. Good APS-C partners include the Sony a6400, the Canon EOS R7, and the Nikon Z50 II.

If you're unsure how the crop factor changes the framing, the sensor sizes guide explains it, and the focal length converter covers depth of field.
