What is the sigma 85mm f 1 4 dg dn art good for?

The Sigma 85mm f/1.4 DG DN Art is a full-frame prime for portraits. The portraits guide calls 85mm the classic full-frame portrait focal length: it gives flattering perspective, soft backgrounds, and a comfortable working distance from your subject.

It has Sony E and L-Mount versions and autofocus, but no stabilisation of its own. On full frame it frames as a true 85mm. On APS-C it behaves like about 128mm, with depth of field closer to f/2.1, which is still a good tight portrait lens there.

It fits a long list of bodies, including the Sony a7 IV and Sony a7 III. If you're starting out with portraits, check the lens page for the full compatibility list.
