Buying Guide
The Pro-S improved on the original Pro with a double-exposure prevention system. The Pro-SD (1990+) uses safer electronic interlocks. Test the rotating back - it should click firmly into both positions. Check bellows for pinholes with a torch. Verify lens shutter works at all speeds. The RB67 is huge but the 6x7 negatives are magnificent. Excellent value for studio use.
