If your camara is a Digital SLR or semi -SLR meaning you can add screw on filter, it is definatly worth getting. especially with the new CCD's on camara that react as if they were film. They capture details almost and if not past film resolution and having a polorizer filter sure does help with the glare of the sky on water and glass and also helps bring out those colors to a bluer or redder as it should be. I use one almost in all my work if you see I always say what I use when I do a shoot in my gallery. bottom line... GET ONE! it's a must!
