Is the sigma 50mm f 1 2 dg dn art worth buying used?

Probably, yes, if you want a fast 50mm. The site doesn't list used prices, so I can't tell you what a fair deal looks like right now. The buying used guide makes the general case: cameras and lenses last a long time, and a body one or two generations old is often most of the camera for much less.

This is a full frame autofocus lens for Sony E and L-Mount, and it isn't stabilised. On APS-C it frames like 75mm. Good pairings include:

• Sony a7 III if you want full frame
• Sony a6400 if you shoot APS-C and like the 75mm look

Budget for a new genuine battery with any used body, since old ones lose capacity.
