Hello all, I got back into photography a bit and I'm experimenting with circular polarizers. Of course, I decided to go the cheap route and bought a kit with a circular polarizer and a ND filter. However, prices vary wildly and while I know you get what you pay for, but what is the difference in performance between an expensive and a cheap polarizer? Maybe in coatings and vignetting?
