[fabrice]

Hi, I wish you could tell me if there is a way to fix the RF vertical adjustment of a zorki 3-C ?
Thanks

You will have to take off the top cover, and then rotate an optical wedge in front of the RF mirror.

Some info about how to take the top cover off might be here: http://rick_oleson.tripod.com/index-58.html

but I'm sure you can google-out more...
