Figure 3-4. Horizontal Lens Shift (EXAMPLE ONLY)

Vertical Lens Shift: The VX-8d 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) below the screen center.

(Vertical lens shift is not possible with the Proteus 1 lens.)

Horizontal Lens Shift: The VX-8d 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.)
