Title: Overpriced, overrated, and greasy
Review: This filter emits some sort of fine grease from the rotating mechanism which is very difficult to get off the glass and also does a good job of gunking up your lens cloth with black grease to be spread to other lenses and filters. The biggest waste of money I have thrown away on a piece of photographic equipment. I will never buy another B+W product again... unless they can show me that their product is somehow worth the exhorbitant price. In this case, it certainly was not. Whenever I see the B+W logo now, I just avoid it and walk away. Don't waste your hard earned money, get a japanese glass version at a fraction of the price and frustration.
