Is the sigma 50mm f 1 4 dg dn art good on aps c?

Yes, it's a good lens on APS-C, but it behaves like a different lens there. The Sigma 50mm f/1.4 DG DN Art frames like a 75mm on APS-C, and its f/1.4 gives about the depth of field of f/2.1. That makes it a tight portrait lens, not a general standard lens.

For people with soft backgrounds, it's a strong choice. It fits Sony E-mount APS-C bodies such as the Sony a6400, Sony a6600 and Sony a6700.

If you want one fast lens for everything on APS-C, I'd look at a 33-35mm f/1.4 to f/1.8 instead. The lenses page explains why. For portrait lens advice, see portraits.
