Yep, long time no speak. Hope things are good with you
I got the 52mm lens and it simply fits into the inner housing - no problem. As my PJ is wall mounted, the fact that its a snug fit is a bonus as I can assume that the filter will not drop out.
I have mine set up with a standard component video driven DVD player and as my original remarks said the filter definately offers a deeper black and a warmth to my PQ that I like.
I can understand what the ritz and Mr. D are saying now, but as I am not using HTPC, I cannot ramp up the green, just the blue. I suppose I can simply let my eyes judge how the filter has affected my PQ and my wife and I like it with it on.
That said, we are far from videophile when it comes to this as we simply want to watch movies, not tweak the PJ all the time. I watched Spiderman recently and the Green Goblins suit certainly looked green enough to me
As I have always said, I am quite into plug and play cinema and out of the box settings are good enough for me at the moment - although I did use zanders pal calibrated 'normal' mode over at AVS forums, which seems much like it did before to be honest

. What I am saying is that depsite tweaking the various picture modes on my 300 I prefer them at the default settings, although I do tweak via my DVD players advanced menu if the picture warrants it.
By the way I think that the picture temp on the PJ is similar to the picture temp options found on my Panasonic w/s TV. Therefore, I conclude that -1/2 = warm, 0 = natural and +1/2 = cool, the latter of which does seem to put more blue/green into the picture if required.
