I just recently purchased a brand new Bessa R3a, and It is definatley taking some getting used to. I am having problems focusing correctly due to the fact that I have been shooting a Auto focus camera for years and used to the convenience. When I line the two images up in the viewfinder, I can't ever really tell when they are lined up perfect. Also.... if I shoot with enough depth-of-field, does it really matter if I am not right on? Another thing, I noticed it has a white window in the front to light up the brightlines.. what happens if I am in a dark room? How do I focus properly and compose?
