After years of reading LF members' comments, and looking at their wonderful shots, I bought a 35mm 1:1.4 Summilux asph. late model (3937xxx). I'd like to think I got it at a good price ($2,350); it arrives on Tuesday. We shall see. In the meantime, I'd be grateful for user comments -- "positive & negative." I plan to mate it with my indomitable M2.
