Figure 3-4. Horizontal Lens Shift (EXAMPLE ONLY)
Vertical Lens Shift: The LS-12HBd 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 LS-12HBd 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.)
