Query: Great loupe!

Quite heavy, solid made loupe. Excellent value for the money. Asahi Optical makes great glass. Large, bright, multicoated ocular. Can see the entire 35mm frame. Can also be focused. I personally like it better than the Rodenstock and the Schneider loupes. Nothing against those two fine brands, but I don't need German-optics with APO glass for viewing negatives. This one is sharp, bright and contrasty. It is perfectly excellent for 1/3 of the cost of the others.This is a "Best Buy"!
