I have the ubiquitous AE100, which until now was sitting on the coffee table in use... I have now made a wall mount for it, to go on the wall behind the sofa. My problem is, that (whilst I was sure I calculated it properly- its clear now I didn't!) that the maximum throw for the screen size I had planned is too short.... I have 4.5m from PJ lens to screen, and only really have room for a 232 (92") diagonal screen - 268cm (105") at a real push.... but even with the 105" screen I can't get the omage quite small enough. My question is - can you get supplementary lenses to adjust the focal length?
