I have the following two Leica M lenses available for sale (I've sold off my M9 and other lenses).
Prices are NET to me (buyer to pay any fees and shipping costs).
Leica 35 Summicron ASPH (black, hand-coded) - $1,700
Serial number: 3873466
Included: Original box, case, metal hood, cap
This lens is in excellent condition with very minor traces of use (no marks or scratches). The lens has been hand-coded with a black sharpie, and was properly recognized by my M9.
Leica 90 Summarit (black, 6-bit coded) - $1,100
Serial number: 4046336
Included: original box, pouch, metal screw-in hood and metal cap
This lens is in excellent condition with no flaws. The rear cap is a generic brand, rather than the original Leica rear cap.
