This polarizer has performed very well for me. I'm an amateur photographer, so my experience with them is fairly limited, but I haven't noticed any defects in the lens. I use it with a Sony A33 mounted on a Sigma 18-200mm lens. At full zoom, there is a bit of vignetting, but it's not horrible. The optics are very clear, and being circular makes it easy to adjust. The only thing that really bothers me is that it's difficult to remove from the lens if fully screwed on (even with light pressure). As such, I find myself not screwing it on all the way so as not to end up in a wrestling match with the lens.
