The Yashica Guy website has a bit on how to calibrate Yashica rangefinders,
may not be of help, but it seems to be all about setting inifinity to the
correct point.

Here is the link.

Good luck, my two Yashica's (circ' 1961 and 1963) are still as accurate as
ever, and great fun to use.

I have just bought 2 external rangefinders to use with a newly acquired
(for curiosity and fun) 6x9 format Bessa 1.
One's a Voigtlander and the other a Watameter.

Anyone know how I can adjust/calibrate either of these, or point me in the
appropriate direction for information, even another newsgroup.

Thought I would try with you guys first (I will be using them on a MF
camera) as on this occasion Google hasn't been my friend.
Thanks
Dave
