Is the leica summicron sl 35mm f 2 asph worth buying used?

Yes, I think it's a good candidate for buying used, as long as you shoot L-Mount. It's a 35mm f/2 prime for full frame, and it's about half the weight of the APO-Summicron-SL 35, so it's the lighter choice if you carry a camera all day. On APS-C L-Mount bodies it frames like 52mm, which is still a useful normal-to-short-telephoto view.

I don't list used prices, so compare current listings yourself before you commit. The general logic in buying used applies: a lens that's a generation or two old can give you most of the performance for much less. Check the condition and budget for a new genuine battery if you're buying a body along with it.
