Interesting. Do you know how it boost the overall light output, and by roughly how much? I wonder if this filter has any affect on the ANSI CR.
Also I know the lens is larger on the VW1000, but I was wondering if this would work for the VW95. There is definite color shift on the VW95 when you tilt your head from right to left.
The filter for 3D projection for the vw1000 that Sony Tech Support sent me was clearly custom-made for the VW1000 in that it clips perfectly to the front of the lens housing. Whether it might be effective in correcting the optical problem on other projectors I don't know. It would depend on whether the source of the problem is the same. The way I got the filter is as follows: I had managed to get through to my dealer's tech support people, the only people inside Sony who have any real knowledge of the projector. I did so by calling the regular number, then getting routed and routed and routed until I finally ended up where I did. The easier way would be to work upwards through your dealer. This was back in July. I had a long chat with the tech support guy about the color shift and also about using a PS3 for photo projection. I ended up writing the "real" instructions for projecting using the PS3 which you can otherwise find on this forum, something I shared with my contact. I then got a cold call from the guy around two months ago telling me that Sony now had this new snap-on filter that would solve the 3D problem. He sent it to me and it did, indeed, solve the problem: You can rotate your head as much as you want and there's no color shift. (The problem may or may not have now been corrected internally in shipping units. I bought mine very early.)
As for the brightness claim I made: Of course, any filter will reduce the number of photons that will pass through, both by reflection and absorption. Nonetheless, in sitting on a ladder, sliding the filter in and out of place, I noticed a small increase in the brightness perceived after passing through the 3D glasses. Given the huge loss in brightness that the 3D glasses cause, it would not take very much to dampen that loss by having a more accurately polarized projection stream. At the same time, I am one person making a subjective observation. It was a careful and methodical observation, but it was not backed up with instruments because I don't have any lying around, so take it for what it's worth. What I will tell you with a high degree of certainty is that it in no way darkened the 3D projection, and the lens appears so crystal clear that I couldn't perceive any darkening effect on normal projection. (Nor could I see any effect at all on normal projection.) The lens does exist, but you will have to expend some effort to get ahold of it. I would love to supply you with a part number, but there was nothing on it or the plain box it came in. Either your dealer can get it or give you the phone number of the dealer's tech support contact for the VW1000 so you can get to someone who can get it.
You do not want the filter if you do not need the filter. It will be seen by no one but you (unless you point it out to your guests when the projector doors are open), but it is not particularly attractive and is just one more thing to have to clean from time to time. The color-shift-with-head-tilt effect is apparently only visible with a few "specialty" screens, one of which, the Black Diamond, I happen to own.Edited by toghome - 11/30/12 at 8:58am
