Re: focus issues with polarising filter

It might be easier if you included the exif data from the shots, and details of the lenses used.

Whilst I'm not particularly keen on polarising filters I have used them on lenses attached to the E-PL1 without issue (effectively the same technology as the E-P1). I wouldn't expect that rotating the ring would be likely to have any effect (other than altering the light levels), though I wouldn't recommend doing it whilst the camera is actually focussing.

Without the exif I do wonder if this is acually an issue of dof/aperture/focus point, rather than related to the filter.
