To organize my thoughts, I've tried to make a list of the improvements that a RS50 might have over the RS20. I'd appreciate any additions, corrections, or any other thoughts you guys might have. (only 2d considered)
--50K --> 70K :1 CR (same as RS35); nice, but not sure how significant.
--Improved Clear Motion Drive ('improved' over what was in the RS35); this is one thing I think I would appreciate, better handling of fast motion. That's one thing I can notice my RS20 lacks.
--Pure Wire Grid Polarizers => better Sharpness?, ANSI CR ? Would be nice if true.
--More lumens; not sure how much of this '1300' we'll see at D65, but presumably something.
--Improved CMS; it was reported that the CMS in the RS35 was 'significantly' improved over that in the RS20, and the new one is presumably no worse (even w/o 'orange').
Have I missed anything that is possibly significant? I'm on Jason's list for a RS50, though of course the final commitment is not until they ship. Would be good to remove some of the above '?', though LG is probably right that we won't be able to do so by shipping time. OTOH, I could wait, as LG suggests. I'm not worried about my RS20 loosing more value, since it will be passed down to daughter/son-in-law; but one might miss the good intro price.
I think that you got it (at least from what I can tell).
I think that we can generally break down the kinds of changes to: Light engine and light path improvements (new polarizers, new panel drivers, new lamp, lamp iris and more efficient light path) and Image Processing Improvements (3d, new frame interpolation, black frame insertion, tons of color mode presets and 7 axis CMS).
Between the two, I am much more interested in the Light Engine/Light Path improvements. The question that I am struggling with is what are these improvements designed to accomplish? Most seem designed to increase brightness while preserving contrast. It seems harder to keep high contrast when you have a higher lumen projector. One important thing that we don't know is are the contrast measurements given at 6500k or, like the lumens are, at 8000k? If they are given at 8000k, then real contrast might be much less than the specs state. So, it could be that the RS50 at 70k:1 might be a lateral (or maybe even backward) move on contrast from an RS20 at 50k:1. In real terms, for contrast, an RS50 might be a brighter RS25 and an RS60 might be a brighter RS35. In addition to knowing about ANSI contrast, this is one reason that I am holding off until we know more. I don't need the extra lumens.
The image processing improvements are much less interesting to me. Having FI that works as people want it to (for those who want to use it
) is something that should have happened last year. But, better late than never, I guess. I AM interested in black frame insertion, which should make film look more film-like. This is actually the thing that I am most interested in seeing. I remain convinced that all of the new gamut presets and the 7 axis CMS are gimmicks or things that most of us would never use. From JVC's perspective, these might increase sales into new markets, but they are not for the home theater crowd.
I really want to upgrade (as I did last year) and I am hoping that my hopes for these projectors are realized. I am hoping for something a little bit sharper (should be because the RS35 is sharper than the RS20) and for something that does a little better with brighter content. For first time buyers or for someone with an older PJ, these projectors are great and an upgrade is a no-brainer, especially if you are into 3d. I am pretty happy with my RS20 so I want to see something on the screen that would justify the upgrade.
