Lens shift, zoom & focus
Motorized lens adjustment
The Prometheus is equipped with a motorized lens shift functionality and a motorized zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the DMD which result in a shifted image on the screen (Off-Axis). A 100% shift means that
the centre point of the projected image is shifted by half the screen size. In other words, the centre point of the projected image falls
together with the outline of the image in an On-Axis projection. Due to mechanical an optical limitations the shift range is limited as
well.
All DP2K lenses have a shift range of 50% up/down and 30% left/right. This range is valid for all throw ratios.

Take into account that the lens focus may slightly drift while the lens is warming up from cold to operation
temperature. This is a typical phenomenon for projection lenses used with high brightness projectors. The
operation temperature of the lens is reached after approximately 30 minutes projection of average video.
