The polarizer was a bit cloudy coming out of the little clear plastic case, but I cleaned it up nicely with a bit of hot breath and the tail of my cotton t-shirt. Is there any other way to clean glass!?
I frankly don't know how good this filter is. And are filters for digital sensors different than those made for film? Does it make a difference? I have no idea.
But regardless, it works nicely on my Panasonic LX5 compact camera, even at the widest setting on the 24mm-90mm (equiv.) zoom.... I should have tried a horizontal shot but I wanted to get the clouds and sky using a vertical shot. Assuming we have another nice day tomorrow I'll give the landscape orientation a try, and see what I get.
The lens adapter is from an aftermarket ebay supplier but the filter end measures 52mm just like the Panasonic adapter. A perfect fit for 52mm filters. It's nice too because my only other polarizers measure 67mm and 58mm. I've used 58mm filters on the LX5 with a 52-to-58 step up ring, but using the right size is always slicker.
Anyway, here's the example I was happy with this afternoon. Nice day, huh? After a week of rain it was nice to get a reprieve. Blue and green are great landscape colors. I am very happy with Panasonic's metering system and always enjoy the live-view histogram.
