This is a very high-quality filter, for those unfamiliar with it...$30 is a STEAL of a price...I do not know the OP jdag, but just wanted to state that the B+W 010 is a very nice clear protective filter,and is what I personally use when I need a clear protective filter, like at the seashore, and during the spring time when trees are literally oozing airborne sap that sticks like varnish!
