The RS-45 is a light canon as well. Should be more like 1025+ lumens for the RS-45 on a new lamp at closest throw, around 900 at mid-zoom.
At farthest throw around 800 lumens. It will drop significantly though in the first 200 hours most likely, I'm guessing at least 10% to 20%.
I don't think the Epson 5010 is as good for movies as the RS-45, but partly it will depend on room conditions and throw distance. If you take the Epson 5010 back to mid-zoom, you're more than likely going to get around 5000:1 Native at best, the Epson's IRIS can bring that up to around 20,000:1 realistically without too much pumping, anything higher and you'll see some IRIS side effects.
The 5010 is closer to the Sony hw30 than it is to the RS-45. The RS-45 has 50,000:1 Native at farthest throw, and I actually measured 48,000:1 so it's not a BS number.
Dynamic Contrast is not as good as native contrast, it can be almost as good in certain scenes, but overall the IRIS closing down isn't a guarantee on how it will affect the scene, but native contrast is more of a guarantee.
