6.5 Lens shift, zoom & focus
Motorized lens adjustment
The D P 2K-S series projector is equipped with a m otorized lens shift an d zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the internal optics of the projector (DMD) whic h results in a s hifted 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 im age in an O n-Axis projection. Due to mechanical and
optical limitations the shift range is limited as well.
All DP2K lenses have a s hift range of 50% up, 50% down, 30% left, and 30% right. This range is valid for all throw ratios. Within
these shift ranges the projector and lens perform excellently. Configuring the projector outside these shift ranges w ill result in a s light
decline of imag e quality.

F Field of v iew.
It’s mechanical p ossible to shift o utside the recommended field of v iew ( ±90% UP/DOWN and ±50%
LEFT/RIGHT), but this will result in a decline of image quality depending on the used lens and the zoom
position of the used lens. Furthermore, shifting too much in both directions will result in a blurred image
corner.
