Work with Lenses

The lens mount secures the primary zoom lens to the projector and provides setup adjustments for correct
boresight, and manually controlled focus, zoom and offsets. See
page 2-17
The optional Intelligent Lens System (ILS) automates the process of adjusting the Focus, Horizontal (X) and
Vertical (Y) Offset, and Zoom in real-time using a motorized lens mount. ILS settings are saved in a file named
ILS Flat or ILS Scope.
An anamorphic lens (1.25x) can be installed into the optional auxiliary lens mount, then swung into place in
front of the primary lens to widen a "squeezed" image into a properly proportioned "scope" anamorphic
cinema display. It is typically used in theatres having side masks that are retracted for "scope" images, or in
theatres having fixed side masking but a very short throw ratio.
