Hello, I'm about to order my ae700. But There is no accurate info about the lens shift. I know, that (said in pdf and manual) that You can't use for example the vertical shift, if the horizontal is at it's maximum or vice versa. Now, I'm dying to know that how much there can be horizontal shift, when the image is shifted so that the top of the image is at same level of the projector lens, when the projector is upside down? Well I say it again: (my english is not so good) Let's say the projector lens is 200 cm from the floor and the TOP of the projected image is also at the same 200 cm. (sorry for the units, but You get the idea) And to project the image as described above, there must be lens shift comparing to zero lens shift position. Now, when the top of the image is at the same level of the lens, I'd like to know, how much can the image be shifted to the left or right from the center position? Of course I will not use keystone, I need the projector to be at zero tilting for best image geometry. And finally, the last question: is there any offset in the lens shift? I mean that in the pdf was an image where the center point of the lens shift (the shift is zero in all directions) resulted the center of the projected image to be at the same point with the projector lens, when viewed from behind of the projector. (hard to describe, sorry) I ask these questions, because I have Z1 now rack-mounted and hanging from the roof. I need somewhat the same lens shift with AE700 as with Z1. I would appreciate any info about the lens shift, thanks very much in advance.
