Figure 3-4. Horizontal Lens Shift
Vertical Lens Shift - VX-2c: The VX-2c zoom lenses (Proteus B through F) provide up to
80% of downward vertical lens shift. For example, with a 96 x 54-inch (16:9) screen, you
can shift the image up to 43.20 inches (1.10 meters) below the screen center. (Upward
vertical lens shift is not possible. Vertical lens shift is not possible in either direction with
the Proteus A lens.)
Horizontal Lens Shift - VX-2c: The VX-2c zoom lenses (Proteus B through F) allow up
to 10% 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 9.60 inches (24.38 cm) left or
right of the screen center. (Horizontal lens shift is not possible with the Proteus A lens.)
