Anyone has this filter?

I use the Hoya Pro1D Circular PL and have no issues. I have always used Hoya and found thier quality to be exceptional.

I own the 77mm version of this one, and have never had problems with it. I would not recommend the one you are considering, because it is an extra-thin one, you only need extra thin ones on ultra-wides, and it would not benefit you on your 17-85 IS or 70-200/4 IS. The extra-thin ones would be good for lenses such as the 10-22mm, but the 67mm filter won;'t work on that lens anyway. Also, circular polarizing filters have no advantage over linear ones except in theory*, the linear ones are actually more effective and cheaper.


*C-PL filters have no polarizing effect in the center. When AF and in-camera metering were introduced it was thought that for those systems to work properly the filter could not be polarized in the center (where the AF point and metering system were located), since polarizers change the light. However, modern cameras have AF points throughout the frame and multi-segment metering also throughout the frame, so any advantage that C-PL filters theoretically have is lost anyway because of camera capabilities.
