I tried the polarizer on some fall trees and was impressed with the overall quality. A great buy at this price point.

Although some previous reviewers have had problems with this product, I have not. Good quality at a reasonable price... and improves the contrast in my photographs... Thank you.

I was looking forward to using this on my trip to Fl. I got this in the mail very quickly as expected from Overstock. Initial disappointment was that the inner "C" ring right on the polarizing lens was loose and showing up on top of the glass. I nudged it back into place with a pencil eraser and it seems to be staying in place. Have not had any additional observable quality flaws...just questionable quality. Used it on my Canon 17-55mm 2.8 lens. Only used it once, not much "sky" darkening effect that I was hoping for but that could be the time of day and the lens. Not given up yet.

This is the exact item I needed for DSLR photos of a landscape for my website. I have two different 77mm lenses and this was a great purchase.

I used this at the Grand Canyon, and the National Park in S. Utah. Big difference in the quality of my pictures. So much that I never took it off. It cut right threw the haze and brought out the true colors. I save $30!

The ring that holds the filter in place is askew. I tried to fix it but didnt want to damage the filter further.
