I puchased a Retina 3c on eBay a little over 2 years ago. This was my "replacement Rangefinder" for the Leica IIIf that I sold.
The Retina is, in my humble opinion, a fine example of old world craftmanship. It is a very solid and well built camera. I believe that back in the 40's and 50's it was considered as a high quality, less expensive alternative to the Lieca by serious amatures and some pros.
Although I did clean lube and adjust the rangefinder, I suspect it might be slightly off at distances closer than infinity.
Can someone on this forum direct me to instructions on how to verify and correct this problem.
Thank you for your help,
Regards to all,
Bill K.
