4.6 Selecting a lens
The projector is delivered without a lens, enabling you to select a lens according to your
desired image size and projection distance. The projector uses a bayonet mount system to
precisely fix the lens in place. The lenses are manual, meaning zoom, focus and iris adjust-
ments are done by hand manually. Lens shift is motorized (horizontally and vertically).
Use only the original projection lenses or lenses that have been approved for use with
the projector.
Figure 4-4. The protection lid
A protection lid is mounted on the projector lens opening to protect the interior of the
projector from dust and damage. The protection lid must always be in place whenever
there is no lens mounted on the projector!
The protection lid must be removed before attaching a lens!
The projection lenses are supplied with protection caps on both the entry and exit
sides. Please keep the caps on until mounting the lens on the projector!
Remove lens protection caps before mounting the lens and using the projector.
