No idea if its worth a penny but I know a fair few here like their old camera. I have in my possession a Voigtlander VF135. Manual focus ring and fstop dial, manual film advance, self timer (mechanical) tripod mount. For some reason it also has a (very odd, and I assume old fashioned) button cell battery, but I cant for the life of me work out what it actually powers. Made of a sold clean grey metal with leather grip strip (fake?) and original leather case. Has a standard flash mount, takes regular 35mm film. Anyone?
