I used the Tiffen 72mm Circular Polarizer on my Canon 28-135mm lens during a recent trip to New York and got very impressive results. This is my first experience with a polarizer so i am not in a position to compare this with anything else in the market but definitively worth the money you pay.
I bought the Tiffen Circular Polarizer because the name is well known and it got great reviews. Shortly after receiving it however I was very disappointed. Although it mounts to the lens firmly, the adjustment ring is very loose and shifts around when making lens adjustments. For the price I expected better quality. On my 18-200 VR lens this filter shows A LOT of vignetting at the edges of the frame. I'm not sure why, but without the filter everything looks fine, with it there's ugly dark shadowing at all four corners. Unfortunately because of my current location I'm forced to continue using this filter, but given the opportunity I would send it back.
This filter puts color back into burnt out desert scenes.
It did what it is supposed to do - Increase color saturation and reduce reflections.
