This may not be the right forum to post this in, but does anyone know of a 17,000 to 18,000 lumen projector-ultra short throw lens combination... something capable of filling a 60 foot wide 30 foot high screen from a very close distance?
Define "ultra" short throw. Go to digitalprojection.com and you'll see a number of projectors that fit your bill in lumens output. Most of them have fixed lens short throw options, somewhere between .6-.8. That's pretty darn short, but not like the new Sony that goes right underneath the screen. Others like Christie probably have something like that too.
Keep in mind it becomes much harder to get a sharp, high quality picture and even focus across your screen with a throw that short. You end up with a rounded lens to achieve throws that short others may chime in here with something specialty at that brightness I'm not aware of.
There is no sharper picture than a fixed short throw lens, period.
But what you are repeatedly failing to disclose is your throw distance in feet.
I am not failing to disclose anything. This is for a story which I need to have grounded in fact. The throw distance needs to be as short as possible, but is not a determined distance. The screen can be from 50-60 feet wide, and 30 feet high.
Frankly, I was a bit confused by your initial comment regarding clarity. It appeared that you were saying that either short throw at .6-.8 OR Sony's extreme short throw compromised picture quality. I didn't know that you were apparently speaking of a variable lens vs a fixed lens.
