BTW, I find the Polarizer kit very useful. In addition to working beautifully with slide film, I use the viewfinder bracket to get pseudo-TTL metering with my yellow, orange, green, and red filters. I screw a 43mm version into the PL viewfinder bracket and a 58mm filter on the lens-- then I don't have to think about filter factors and exposure compensation. I pretty much keep the PL bracket on the camera permanently.
Does anyone else do this?
