Hoya Digital Circular Polarizing Screw in Filter

This is one of the nicest photographic filters I've ever used. I have been an amateur photographer since I was 8 years old, and have tried many different filters and polarizers. Did I say 8 years old??? ...that was back in 1959!!! Back in the late '70's, my wife and I took the Nikon School of Photography coarse in Anchorage. This is a nice filter, smooth operation, works very well. You can see the fine green-ish coating on the lens surface. The coatings reduce flare and reflection which allows more light to pass through to the sensor/recording media. The circular orientated filter is matched to today's digital cameras, and is especially important if your camera has auto-focus. The polarizing filter reduces reflection in the scene, darkens blue sky, brightens white clouds. I also enjoy the deeper saturation of colors due to removal of surface reflections. My wife and I just toured the south-central part of our state imaging the beautiful colors of fall here in Alaska. True leaf colors show through in landscapes. Better skin tones in portraits. Even pet photos (and wild animal photos of moose, bears, and bald eagles) are inhanced due to less light reflecting from their fur/feather coats. Just remember that the polarizer cuts light by half, therefore you must compensate by increasing exposure one stop. Most cameras do that automaticlally and it is not a problem at all, just something to know and understand. I definately recommend this filter to everyone who owns a camera, both hobyists and professionals. You can't beat Hoya, especially their multi-coated and super multi-coated filters! I have other filters made by Hoya and these are very high quality. Paying for the super multi-coatings is well worth the investment.
