Thanks for all the comments, I've been away for the weekend seeing some ultra, ultra high definition in3D without glasses (aka a concert at the Albert Hall
Rich: As 5mark says my intention is just to use Lumagen 'shrink' for menus and trailers rather than keep zooming in and out if I know the main feature is 2.35:1 then I'll just use that lens memory and shrink the menus before the film starts. For 16:9 I would use another lens memory so that I see the full 1:1 pixel mapped (albeit 'wobbulated' to 2160p). In both cases the main feature would be viewed at 1:1 pixel mapped.
CRGINC: I have previously zoomed so I know how big an area the bars cover: It's not too bad at the top as my screen wall is painted dark brown, though below the screen my TV partly shows, so I added a wide black velvet strip which also used to serve as a 'screen' for subtitles before I was able to shift them with my Oppo player. I might make some changes but I think I've got the masking side covered (and plan to finally add some side masking too for 16:9). I know what you mean about upscaling: My Lumagen can make a pretty decent job of upscaling DVDs, though I don't seem to watch many these days.
Gary: I might take my lens along (also see below) to my demo, but more for info. I know it isn't true 4K, but ultimately a zoomed X55 should put a higher pixel density on the screen than a 1080p plus lens. If I can see the pixels on the zoomed X55 then I would be able to see them now with my HD350 and Isco which I can't. I couldn't see them when I used to zoom with the HD350, but the increased denisty did do something to improve the image, so hopefully the X55 would improve slightly upon that. Leaving the lens in place full time isn't an option, but more due to cosmetic reasons: I'm building a floating shelf for the (white) X35/X55 which will be painted the same colour as the rear wall to make the projector as discrete looking as possible. Leaving the black Isco in front all the time would detract from the clean lines we're hoping for: My OH has been pretty understanding about my other projector related plans for the room and the Z3 3.0 I bought earlier this year as a weekend 'toy' so I suppose I have to concede this point.
It does worry me that you know where I live though Gary.
There was a slim chance that I would get to see the X35, X55, VW50ES and Epson9000 together today at a fellow forum member's house, but I think the dealer did't get the JVCs in time.
I had lent him my lens as he wanted to compare the Sony plus lens against the X55 without, but I couldn't make it due to my London weekend unless I got back in time. I'll probably have to arrange later this week or maybe next weekend if he has a slot.
I think that the time will come when I'll need to dispose of the lens (sorry Gary
), so doing it now seems a chance to move up to 'faux' 4K sooner than I'd thought: Longer term we have some changes planned for our room which would mean that any projector will have to 'fire' across the room rather than down it. This would mean a much shorter throw, so pincushion would become an issue with a lens, so another minus for keeping the lens even if it would work OK with Eshift now. So long as I end up with an improvement over what I'm currently doing it would be worthwhile: In a way I don't want to know if it could look better with Eshift plus
lens as selling the lens helps justify the extra expense as I hadn't even planed on replacing my projector this year. In fact at one point I gave it to a relative to use for a while, but got it back again and rekindled my interest.
EDIT: Managed to get round to see the end of an X55 demo and have to say I' very impressed with the Eshift: Right up to the screen and the pixels completely disappear (even zoomed to fill a 4 metre wide 2.40:1 screen. Sat back in my seat I liked the difference in apparent sharpness with Eshift on (using the 'Film' setting as some others seemed a bit too much for my taste). The motion seemed smoother than my HD350, but I gather this has been improved on previous models to mine, so maybe not a specific X55 improvement.
The guy who had the demos and borrowed my lens would buy it off me if I decide to go for an X55, so some hard thinking tonight so I can order the right projector and let the lens buyer know if he can have it from me.
