Lens shift range The lens shift range represents the distance in percent (%) by which the lens can be shifted from the center of the projected image. The lens shift range is regarded as 0% when the point (A) in the illustration (point where a line drawn from the center of the lens and the projected image cross at right angles) is aligned with the center of the projected image and full width or full height of the projected image is regarded as 100%.

Lens shift range
The lens shift range represents the distance in percent (%) by which the lens can be shifted from the
center of the projected image. The lens shift range is regarded as 0% when the point (A) in the illustration
(point where a line drawn from the center of the lens and the projected image cross at right angles) is
aligned with the center of the projected image and full width or full height of the projected image is
regarded as 100%.
