I've been experimenting with my new Nikon waist level finder that someone gave me. It works pretty slick, but you have to get used to it. A totally different perspective. Nobody knows you're taking their picture. Anyway......has anyone out there tried this? The one thing I don't like is it seems to allow dirt/dust to get onto the focusing screen. Is this a known problem or is there a piece of glass that's supposed to be in there? (like the normal finder - I have the high eyepoint). It's neat experimenting with a feeble attempt at street photography...for those who may be a little shy....
