Title: Simply works!
Review: I recently bought a Canon Digital Rebel XT, and the first thing I noticed was the glare I would get from roofs of buildings, wtater, etc.... I'm just starting out learning photography. It seems I needed a circular polarizer for my lens. Canon seemed kind of expensive, so I ordered this.The circular polarizer works great! I guess the UV filter is good too, although I can't really tell the difference. Just don't bother using the polarizer indoors since it essentially blocks half the light.
