I know the mantra that everyone hears is "immediately buy a UV filter and put it on and never take it off". Think about it -- you bought a high-def camera with a Leica lens... how exactly do you think forcing it to look at everything through a $10 filter is going to be a good thing?
That made me laugh. Barry as you know I am 100% with you here.
Back to the PL ... its like AMEX, never leave home without it. But you must be discerning. Put it on, check the image on a HD monitor, take it off, check focus. Seriously a crap PL can be as useful as a tit on a bull.
