Looks like the one I was considering isn't multi-coated, and I agree that it should have that. However, I've never found a hood to be necessary with a polarizer. The only other filters I use are red, green and yellow for black and white. I'll buy those to fit each lens. > The sensitivity to LP vs CP can affect both AF sensors and metering > sensors, depending upon how a particular camera is designed.
