Yes.
One trap which I have fallen into far too many times occurs when making
manual exposures. I set the exposure and use it for several shots in
sequence. But when focussing for each shot the front element of the
lens (e.g. Zuiko 35-70 f4) turns, and the polarizer turns with it,
altering the exposure.

This raises a question I have been wondering about for some time. How
does a "circular" polarizer work? Presumably it is in two layers, with
the first one polarizing "linearly", since that's what polarization
is, and the second one randomizing the plane of polarization. If the
mechanism somehow depends on quantum effects, is it uniform with respect
to wavelength and intensity, or do circular polarizers introduce visual
artefacts?
