Thanks for all the sound advice!
Thing is, I use the M3 quite a lot, but Nightfly has a good point, I could start by making an effort to bring it with me even more at times when I normally would leave it at home. Could also try getting a smaller lens for the M3, compared to what I already have,the Summicron 50 and the Jupiters (3 and 8); like an old Elmar 3.5. Perhaps getting a small bag of some kind could make it easier to bring it along in everyday life.
Several have mentioned getting a Barnack, which is something I am quite interested in. I have no real experience with Barnacks, but they seem significantly smaller than the M models, as is also the CL. Maybe my next camera will be a Barnack ...
Rollei 35s and Contaxes, esp. the original T, sound interesting, but a bit like the Minox.
So many cameras, so little time and money!
Antti: nice to discover another rangefinder enthusiast from Lund, we must get together sometime. What a coincidence, your son appearing
in this shot on my photoblog! I don't know him, it was just a casual street photo shot where he appeared; he has also commented the picture, and now you appear here on RFF. Small world ...
