Did shoot-out 5030 vs. new Sony 40ES (got at local Best Buy for $1,995 - deal!).
Ended up keeping 5030. Short of it: better blacks.
I tested all my standard dark favs: Alien, Blade Runner, 2001, Suspiria (of course!), NOES, Drive, There Will be Blood. Yes, I have eclectic taste. Even tested The Tourist, some lovely cinematography with I'm sure a few drinking games in there somewhere.
Time again the Epson had deeper blacks. I'm ornery about this kind of thing, spend a lot of my time in edit suites cutting videos. Color correction & grading are two of my favorite past times.
Also, the Sony -- and I'm convinced it's still a great projector -- proved to be more "digital". It seemed more pixelated. And the noise was less cinematic, if that makes sense. The gorgeous scene when Bond is headed in the classic Aston to Skyfall is perfect test material imho.
Thanks to the 5030's stellar lens shift ability, I was able to adjust the lift so it drops from ceiling less (see pics, though it's even less now). There was no noticeable image distortion except perhaps for the faintest pincushion at bottom - that was more pronounced on the 40ES.
Other pros for the Epson: bright! motorized shutter cover (sweet), and brilliant 3D (though I don't use it much).
About the only downside is the noise as everyone as alluded to already. The Sony is almost completely silent... all the time. The 5030 does make fairly obvious noise in normal mode. Thankfully ECO is far better, so that's okay by me.
I'll write more soon on my findings. I upgraded from a 7 year-old Panasonic AX100 that was quite the beast - only on my 2nd bulb!
