Thanks smudger. Your description of the problem is the first I have encountered in any forum (and I've been combing them for solutions for weeks now) and I'm sceptical about the explanation. It doesn't make sense that if the original magnifier in the waist level finder (WLF) is not positioned correctly that it would prevent one from focusing. Sure the image viewed through the WLF won't be sharp, but at least when it is as sharp as it can get then that is the right point. I can't see a need to add a second lens in the WLF. Please try and convince me otherwise.
