You would lose a bit less than two stops of light using the
polarizer - possibly not a disadvantage when outdoors, but
not ideal indoors. Use a UV for protection, exchange it for
the polarizer when wanted. They are fun to use on a video
camera - try aiming at a shallow pool of water with fall
leaves in it and rotate the filter while recording (and
many other things...;-). The polarizer is also usefull
for perking up the sometimes dull color of one-chip
cameras. For AF and some exposure systems, a "circular"
type polarizer is recommended, though I have had good
luck with standard-type polarizers.
