My 50ES came in a couple of days ago. Unfortunately, my previous mount would not fit the Sony, so i can't ceiling mount until I can get a new mount. I had a quick look with it set up on a table. The image seemed to be at a slight roll angle, but it may have been the projector legs weren't all zeroed. Out of the box, the convergence wasn't great on a white grid test pattern. I did a quick panel adjustment - shifted red 5/4 clicks (V/H). Blue needed a couple clicks in each axis. Convergence is now very acceptable, I just hope there's no downside to using the panel shift.
This projector is very bright as most have said. It's noticeably brighter than my old Infocus 7210 (720P) ever was and that had a reputation as being a light cannon. It's also VERY quiet. even right behind it at High lamp setting it was inaudible. This will be a welcome improvement over the Infocus. I couldn't see any uniformity issues with all-white or all-black scenes, no hot corners as some have reported. Black levels were a huge improvement over my old DLP unit. I could only just barely make out the black bars on wide (2.35 aspect ratio) movies. The dynamic iris was imperceptible.
I watched some 2-D and the picture had a lot of pop. Significantly more so that the Infocus 7210. Those worried about losing the DLP pop, need not concern themselves. Colors seemed accurate so far but I will need to see some more demanding material before I can say anything definitive. Sharpness seemed fine and focus seemed pretty uniform. The picture was definitely sharper than I remember my old Infocus being (I haven't run it in 3 months) but I wouldn't say it blew it away, as far as sharpness specifically is concerned. DLP just tend to be very sharp, with the very defined pixel structure making them seemed even sharper still. Also, the Infocus was about $7K when first released, so one would assume a top quality lens was used. I also didn't see any drift in focus as the unit warmed up. When one add the increase in sharpness, extra pop, hugely improved black levels, richer colors and lack of noise, the Sony 2-D image was a huge jump up over the old Infocus, which probably should be expected given that the 7210 is 5 or 6 years old.
3-D was plenty bright. However the image seemed to lack some solidity. Brightly lit foreground images seemed to have a slight flicker. it was almost as if they disappeared for every 3rd or 4th frame (i'm sure they didn't - just trying to describe the perceived effect).
I had to pack everything up as my chairs were supposed to be delivered today (by 2 PM at the latest) and I needed to have my room empty so the delivery guys could set up my chairs without knocking over the new projector. 5:30 PM and not even a call, BAH!!!. I'll set everything back up again and play around some more in a bit.
