@jrista: Your call. I got enough information, and a polariser, so I'm happy.

comment What considerations are there when buying a polarising filter?
@itai: My friendly neighbourhood physicist agrees with mattdm on this: the light is still polarised, but has components in all linear directions.

@mattdm: Possibly: at the time of asking I wasn't sure if the camera had any bearing on the matter. Now that I know otherwise, then it is pretty much a duplicate. I leave it to your discretion as to whether to close it or not.

@itai: thanks for the links, that's useful. (My "passing physics professor" had worked out what it must be in the meantime but nice to have it confirmed.)

Thanks for the answer. One query on your first point: the Olympus isn't a DSLR and focusses by contrast. Is a circular polariser still going to work with that?

PS: I'm confused as to what "circular" and "linear" mean when referring to polarising filters. Can anyone link to a good guide that explains it?
