I have a canon EOS 1000D with 18-55 mm lens. I use a Hoya CIR-PL. Even after setting the camera in P mode, ev at -2 and white balance in daylight setting, camera seems to correct the polarizer effect. Putting in manual focus worked. Is there a way to do this in autofocus. Kindly help.
Because the front element on the 18-55 rotates while focusing, you'd have to acquire AF lock first, then rotate your polarizer without moving the front element (because that would change the focus distance). It's not easy, but as you move up the Canon lens range, moving front elements aren't present in the designs. Unfortunately as it stands, if you adjust your polarizer for maximum effect and then try to focus, you're going to have to readjust your polarizer for the shot because it's likely in the wrong orientation again.
