OVERVIEW
LBV00056; Revision C - 01/03/03
Lenses
Five lenses have been developed specifically for the LIGHTNING sx and LIGHT-
NING gv
range of projectors with zoom ratios of 1.5 - 2.0:1, 2.0 - 2.5, 2.5 - 4.0:1,
4.0 - 7.0:1. In addition a fixed lens of 1.2:1 (actual 1.5:1) is available.
Using a lens adapter, the following gv series lenses may also be used, albeit with
modified throw ratios and limited lens shift capabilities: 0.82:1 (fixed) and zoom
lenses of 1.5 - 2.5:1, 2.5 - 4.0:1, 4.0 -7.0:1 and 7.0 - 15.0:1.
Motorised Lens Mount
The LIGHTNING projectors incorporate a motorised lens mount. This mounting
allows you to control the zoom/focus via the remote control.
As the lens mount attaches to the lens, the mounting mechanism must be released
before a lens can be fitted or removed. To release the lens mount turn the mounting
lever anti-clockwise (upwards). After fitting a lens the lever should be turned
clockwise to engage the mechanism.
When engaging the lens mount, the lens may have to be rotated slightly in order
for the lens mounting to connect correctly.
