I intend to buy a circular polarizer filter in 52mm for my 28, 35, and 50mm Nikkor lenses. I will use it mainly for fall scenics in North Carolina. I have always had good results with Hoya filters, however, B&W seem to be highly regarded, as well as the more expensive Nikon filter. I will be using my 12 MP D300, but I intend to get the 20MP D500 in the future. I want to choose a filter that will not degrade image quality. And, yes, I have researched the topic but a lot of the information about circular polarizers on the Internet is dated and/or inconclusive. So what are your recommendations? Hoya (possibly the Pro-1 digital multicoated), B&W (possibly the MRC or the Kaesemann High Transmission MRC), or the Nikon Circular Polarizer II?
