I am in the market for a Leica lens and would prefer to buy used as the prices for the new lenses are astronomical!! Is there any old Leica lens I should stay away from? It seems that all the reviews of any Leica lenses are glowing!! Would like to hear people's opinions.
Oh, and if you can't think of a bad Leica lens and would like to recommend one that is of good value, include that in too ;-)
