M43 and old film circular polarizer

Thanks for the suggestions, but I do think that I did everything the correct way.

It just seems the changeis much less than what I used to see when the CP was used on old photo-film glass.

Does anybody use a specific CP with a GX1 and the 14-42mm.
Or does anybody use a CP with any m43 gear?

I might check a store to see if they let me put a new CP on my system just to test whether I see any difference to my current one.

Thanks for the help.
