Which LTM to buy as a user?
Not interested in collecting, but just want a LTM for nostalgia or fun use? Then go for the IIIC's, manufactured from 1940-51. These are cheap, easy to buy and collectors aren't as interested as so many of them were made - approximately 130 000 units.

For lenses, use the new Voigtländer Bessa screw mount optics!
