Is the sigma 105mm f 2 8 dg dn macro art good on aps c?

Yes, it works on APS-C. The lens is made for full frame, but it fits Sony E APS-C bodies too. On those it frames like about 158mm on full frame, and f/2.8 gives about the depth of field of f/4.2. That makes it a good fit if you want reach for close-up detail, portraits, or small subjects from a distance.

Good APS-C bodies to pair it with from the list are the Sony a6700, the Sony a6600, and the Sony a6400. For the maths behind the crop, see the Focal length converter, and for what the smaller sensor trades away, see Sensor sizes.
