Anyone know the throw distance for the upcoming 4805?
http://www.infocus.com/service/softw...&itemId=sp4805 Pick the 4805 from the drop-down menu.
I have to admit I'm a little paranoid about that calculator. It uses (almost) the same numbers as the x1/4800 calculator, and you have to wonder if they just stuck those numbers in until they can update it. The initial spec sheet for the 4805 was a quick cut and paste, and was loaded with inaccurate specs. Does anyone know if the 4805 does in fact uses the same lens as the x1/4800?

The throw ratio of the 4805 is 1.77-2.13:1 (distance to screen / screen width)." http://www.avsforum.com/avs-vb/showt...20#post3256820 "The 4805 uses the same lens as the X1, so the zoom ratio will also be the same." Maybe those two posts from BobW at InFocus would help? See if the math works.
Does that mean it will have a longer throw or shorter than the X1? Thanks.
Shorter. If I'm calculating correctly (and there's no guarantee of that), the x1 has a throw ratio of 1.89-2.27:1. That means that with the projector 17 feet back, the X1 will have a screen width (on 16:9 material) of 89.9" to 107.9", while the 4805 will have a screen width of 95.8" to 115.3". This also means that I'm not going to make definite plans on projector placement until the thing is actually available!
