using the normal projection position as a starting point.

lenses:
GT13ZL/13ZLB values in parentheses
Up: 0.5V (0.43V) (V: height of projected image)
Down: 0.5V (0.43V)
Right: 0.32H (H: width of projected image)
Left: 0.32H
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.
