I am a new Leica M user and recently got a deal on both a 35mm F1.4 (summilux non asph) series 7 lens and a 35 summarit (6 bit coded.) I am debating selling one and am having difficulties making a decision. Any advice on performance/known issues, etc? I love the idea of a f1.4 but does the optical design of the newer f2.5 make up for the loss of f-stop? I am using them on an M9 and am shooting travel and documentary work.
Thanks in advance!
