voigtlander 35mm 2.5
If you are speaking of the Voigtlander Color Skopar Classic, I have that lens.
Yes, it works beautifully! The only caveat is that it will require two adapters - the LTM to M AND the Leica M to NEX adapters. The Color Skopar is a screw mount lens. I was fortunate to find a mint used one sold with the LTM to M adapter included.
Go for it! Image quality and handling are both first rate. In fact, I like the Color Skopar, in every regard, much better than my Nokton 40/1.4 Classic.
