Is the sigma 135mm f 1 4 dg art good on aps c?

Yes, it works on APS-C, though it's really a full-frame lens. On an APS-C body it frames like about 202mm, so it becomes a fairly long telephoto. The f/1.4 aperture still gives plenty of background blur, roughly what f/2.1 would give there.

It suits tight headshots and portraits outdoors, where you can stand well back from your subject. Bodies it fits include the Sony a6400, a6700 and ZV-E10 II. If you want a more everyday APS-C portrait lens, read the portraits guide first. For how focal lengths translate across sensors, see sensor sizes and the focal length notes.
