Is the sigma 28 105mm f 2 8 dg dn art worth buying used?

Yes, I'd buy this one used. It's a full frame zoom with f/2.8 across the whole range and autofocus, and it's made for Sony E and L-Mount. The catch is that it isn't stabilised, so you'll rely on shutter speed to keep shots sharp.

On a full frame body like the Sony a7 III, it frames as marked, 28-105mm. On an APS-C body like the Sony a6400, it frames like 42-158mm, which gives you useful reach there.

Buying used is one of the best ways to afford good gear, as the buying used guide explains. If you're buying a body alongside it, budget for a new genuine battery.
