Is the sony fe 24 105mm f 4 g oss worth buying used?
Yes, I'd buy this one used. Lenses hold their value well, and a used copy is one of the best ways to afford good gear, as I explain in buying used. This is a stabilised f/4 zoom covering 24-105mm on full frame, so it's a flexible everyday lens.
It fits a long list of Sony E bodies, from the a7 up to the a7R VI, plus plenty of APS-C models like the a6400 and a6700. On an APS-C body it frames roughly like 36-158mm. For a sensible everyday kit, I'd pair it with a full-frame a7 III or a7 IV.
Check the lens page for the full list of compatible cameras before you buy, so you know your body is on it.
