Well not exact measurements as Im not at home right now, but the PJ is on a table about 3/3.5m from the wall and I am getting an image that is 2.1m wide (just using a wall - screen should arrive today). I am putting an 84" screen in but I will need to mount the PJ about 3m back from the screen to get the correct image size.
As I say, nothing to compare it to but I was amazed at how large an image i could get as it is not advertised as short throw. Infact its a bit too large as right now it wraps onto the side walls (like a poor mans Imax ;o) ). No manual zoom which is a pain, but I am getting a false ceiling put in so am fortunate that I can mount it in exactly the correct place. You do have a manual focus to ensure the image is sharp. I have not had to mess around with keystone.
