52MM Color Lens Filter Kit 5 Pcs for Nikon D40 D50 D40X - eBay (item 180471620244 end time Feb-20-10 11:15:15 PST) I keep seeing these all over and I've asked about them. I want to get some---not sure exactly what they do lol but I read they have nice effects on the colors---like blue filter (for water and clouds-sky etc)....orange or red for fall leaves... Is that true? If so is it one size fits most? If they actually do something that is noticeable and the quality of the pics isn't screwed----why not? Does anyone use these??? *color filters , or Micro filters.?
