Vertical Lens Shift: The LS-10i zoom lenses (Proteus 2 through 6) provide up to 65% of vertical lens shift in either direction (up or down). For example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 35.10 inches (0.89 meters) above or below the screen center. (Vertical lens shift is not possible with the Proteus 1 lens.)
Horizontal Lens Shift: The LS-10i zoom lenses (Proteus 2 through 6) allow up to 30% of horizontal lens shift in either direction (left or right). For example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 28.80 inches (73.15 cm) left or right of the screen center. (Horizontal lens shift is not possible with the Proteus 1 lens.)
