Watch out for hazy film on the filter!"After I bought my B&W polarizer, I noticed that all my shots were ""soft""--as if I was using a diffuser. It noticeably killed contrast right in the viewing of my E-M5. I couldn't understand why. I thought I got a bad filter until I contacted a pro wildlife photographer, who suggested that maybe the plastic case might be ""gassing out"" and leaving a film on the filter. I looked any my filter under a bright lamp and sure enough--there was a layer of film on the surface! So if you buy this filter, be sure to inspect and clean the filter before using it, otherwise you'll be very disappointed with the results."
