Is the yongnuo yn50mm f 1 8 df dsm good on aps c?

Yes, it works well on APS-C. It's a full-frame lens, but it fits Sony E and Nikon Z bodies, and on APS-C it frames like a 75mm lens. At f/1.8 it gives roughly the background blur of f/2.7 on full frame, which is a nice portrait look. The portraits guide calls this focal length a classic APS-C portrait lens, so it suits people shots well.

Good APS-C pairings from the catalogue include the Sony a6400, Sony a6700 and Nikon Z50 II.

If you'd rather have a lens made for APS-C, look at the Yongnuo YN50mm f/1.8 DA DSM. For how the crop factor changes depth of field, see the focal length converter.
