Is the leica summilux m 21mm f 1 4 asph worth buying used?

Yes, I think it's worth a look used, but I can't tell you what a fair price is because this site doesn't list prices. Check what similar lenses are selling for before you commit.

This is a manual-focus 21mm f/1.4 for full frame Leica M bodies, and it's wider than the rangefinder frame lines, so you'll need an external finder, live view or an EVF to frame it properly. Plenty of bodies fit it, from the Leica M9 to the Leica M11, so you can pick one that suits your budget.

The buying used guide makes the general case: a lens or body from a generation or two back often gives you most of the performance for much less. Just check the condition carefully before you pay.
