Lens Shift Adjustable Range
The top right diagram shows the location of the image position in the lens. The lens can be shifted within the shaded area as shown
using the normal projection position as a starting point.
Maximum Possible Range for GT20ZL lens:
Up:
0.64V
(V: height of projected image )
Down: 0.64V
Right:
0.33H
(H:
width of projected image)
Left: 0.33H
Note: Check availability of GT19ZL. (GT10RL is discontinued)
Note: Lens shift is not available on the GT10RL/GT10RLB rear lenses. GT10RL/GT10RLB should be used only for “zero
degree/no-offset” applications.
Note: If the lens is shifted in two directions combined, maximum range in either direction cannot be obtained due to rounded off
area of lens. (example: shift up and right) See top right diagram.
