B&W circ polarizer
I just got my new B&W Kaesman Circular Polarizer yesterday afternoon and I am really impressed. It is a 67 mm size vs the 52mm size Tiffen circ polarizer I had for my 50mm lens. There's no comparison in build quality or smoothness in operation. Of course the price was a lot more for the B&W and it is at least 25 years newer in technology. Just taken a few shots of clouds yesterday afternoon as it was getting late.
