[QUOTE=BrianPhotog;575297]For a little more on the inner workings, I have a DIY article on R2A/R3A rangefinder adjustment at: http://www.cosina-voigtlander.com/content/view/58/82/.
I checked out your pages and bookmarked them. It's very interesting. I'm wondering if the whole alignment issue you discuss is the issue I'm having.
When I use the focus patch on my r3a, I can usually line up high contrast vertical lines, but it doesn't quite work with other things. Example: I'm focusing on a face with glasses. When the nose is focused according to patch alignment, I notice the rims on the glasses are not. Is this a depth of field issue?
