Beautiful lens. One of the few ultra wide-angle lenses for Leica M cameras with good edge sharpness. They have been involved with Camera Quest for almost 20 years and have never misrepresented the product. They are wonderful to order. You get what you pay for. I find the Voighlander to be a good, very sharp, and affordable option for Leica lenses that cost thousands of dollars more. But that doesn't mean that I can say or draw any other conclusion about the current !Leica M lenses than that I can no longer afford them. If I could I would buy them but I don't think Leica has anything in the Voighlander Hyper class 10mm glass and if they did it would probably be a $10k price tag! to bring this lens to us citizens. Voighlander just keeps getting better.
