i just bought a couple lens filters for my digital rebel this afternoon. i got a uv lens, a polarized lens, and a y2 lense(yellow color filter) that was said to be good for b&w shots. just curious if these would be of any use for a digital camera. i probably should have asked before i bought them. but i was gonan get a uv filter anyway... and then the polarizer i would use if i were ever to take my 50mm out in the sun. the yellow is kind of part of the deal, it was buy 2 get 1 freee kinda thing. the yellow was the free one. any thoughts? so far about the yellow lens, i havent noticed anything spectacular about it.
