Having eaten my Nikon lens 18mm with this Skylight Filter 1B of Hoya - 105 mm to prevent damage and knew very best experiences made with it, I now bought for my new Nikon lens 18-200 mm in size from the filter 72 mm. Because the skylight in contrast to ordinary UV filter is not neutral but has a slight tint, it affects color photography, especially skin tones, which can in my opinion be very positive. The reduction of Blue stitches on location as well as reflections I can also confirm. With the quality of the filter I am extremely satisfied.
