Is the canon ef 50mm f 1 2l usm worth buying used?

Yes, I think it's worth a look used. It's a fast 50mm, and the used market is where good glass like this makes the most sense. On full frame it frames as a true 50mm. It fits a long list of Canon EF bodies, from the Canon EOS 5D Mark IV and Canon EOS 6D Mark II on full frame to the Canon EOS 80D on APS-C, where it frames like an 80mm.

It isn't stabilised, so for low light you'll be relying on that f/1.2 aperture. Check the lens for wear, and budget for a new genuine battery with whatever body you pair it with. The buying used guide covers the rest.
