I bought a circular polarising filter today for my new camera. It was a Hoya, and on the package it said: Hoya 52mm, 0.75 pitch. What does 0.75 pitch mean? If there's more to polarising filters than meets the eye (no pun intended) could you please explain. And thank you for the article above.

EDITOR: The pitch is the size of the screw thread (grooves) that you twist to attach the polarising filter to the lens. 0.75 pitch is standard for modern camera lenses and it simply means that each full 360 degree twist of the filter moves it 0.75mm into the camera thread.
