What cameras fit the sigma 50mm f 1 2 dg dn art?
The Sigma 50mm f/1.2 DG DN Art is made for Sony E and L-Mount, so it fits any body in those two mounts. That covers a long list of full frame and APS-C cameras from Sony, Leica and Panasonic, plus a couple from Sigma.
For a sensible everyday pairing, I'd start with the Sony a7 III or Sony a7 IV. On full frame the lens frames as marked, at 50mm. If you want something smaller, the Sony a6400 or Sony a6600 also fit. On APS-C it frames like 75mm, and f/1.2 gives about the depth of field of f/1.8. For L-Mount, the Panasonic Lumix S5 II is a solid full frame choice.
