Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens.
• They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc.
• They also saturate colors and increase contrast.

I read the review about this filter being blurry as I'm about to purchase one for a new lens. I did some tests with my old lens and my old Sunpak filter and they are correct! The images are noticably blurry with the filter in place. I was barely getting into photo with the old setup, only now am I more serious and I blamed previous blurry images on myself. D'oh. I'll be springing for the higher-end equipment on this one.
Great value for the money. There are better, but this one certainly suffices!
Have had this filter for several years with no problem. Works great everytime!
I should have know better. The cliche "You get what you pay for" could not be more true when it comes to this filter. I bought this for my 40D (I know I know - Why spend all that money on a great camera and skimp on the filter? I have learned my lesson). I loaded up the mountain bike, threw the camera gear into my backpack and away I went. After spending several grueling hours in the mountains I arrived home, excited to pull the images from my camera. I was in store for a major disappointment. Every single picture taken with the Sunpak Polarizer filter was blurry. Big time bummer! Don't waste your money on this filter. Spend a little more for a Hoya or B+W and save yourself the agony of a wasted photoshoot. I also carried along the Sunpak UV filter and surprisingly pictures taken with it were razor sharp. But the Polarizer...No No No No No No...stay away. Learn from my pain :)
