When Sony ships me a unit in October, I will let you know. Nothing pertaining to your questioms would be discernable under any packaged demo at Cedia.
This appears to be some sort of evolutionary improvement over the HW30AES. There is no 4K on this machine or anything to fake 4K. RC as used by Sony in the past does not include the algs used to deinterlace and scale or just scale to 1920 x 1080, the native resolution of each of the three SXRD panels in the projector. Just like in my Sony VPL-vw1000ES, RC can be completely shut off amd yes er ree, the machine will still output the native resolution of the panels. RC is a two axis process, one axis sharpens the picture, or in Sony words, increases the resolution in the sense of detail embedded in each pixel. The trade off is that noise is added and the second axis control must be used to employ filtering to get rid of the noise. Where these two controls are set depends on user preference. At least that's the way it is in my 1000ES. With respect to the 1000ES 3840 x 2160 or 4096 x 2160, most prefer the resolution set at a very low level and the noise control likewise set very low. With respect to 1080p vs 4K panels, I have no clue as to what RC will add or what settings most will prefer.
Brighter as far as 3D is concerned is a good thing and providing a more aggressive DI setting gives the user an option to obtain better blacks but perhaps with greater iris artifacts. Once again this will depend on the user and Sony's DI is very very good, the best in the business.
Having greater lens shift using the same size lens and panels is only a way of giving the user a way to degrade the picture he could otherwise have using little or a small amount of offset. I have no clue if the lens size has increased pr
whether ;ens qua;ity has been improved over the 30.The 30 is a fine machine amd I would expect that Sony has improved it a bit with the 50. How much we shall see.
