I just purchased a Retina IIc (made between 1954-1957 I believe) a couple of weeks ago. I never used a rangefinder before so I am both excited and anxious. For anyone familiar with this camera or rangefinders similar to it, do you have any tips for correcting the parallax error? I plan to use a tripod when I shot with it, so should I adjust my tripod according to make for this error? If anyone can provide any tips, I would really appreciate it.
