I have a UV that is on all the time - easier to replace a scratched one than the whole camcorder. I also have ND and Polarizer. By the way if you do get a polarizer make sure it is "cicular" or you may have problems with autofocus. I also have a pice of 1/8 Blue that I hold in front of the lens when I white balance, if I want a slightly "warmer balance"
