3.5 Lens shift, zoom & focus
Motorized lens adjustment
The Thor is equipped with a motorized lens shift and zoom & focus functionality.
Maximum shift range
The lens can be shifted with respect to the internal optics of the projector (DMD) which results 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 and optical limitations the shift range is limited as well.
All DC4K lenses have a shift range of 50% up, 50% down, 17% left, and 17% 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 will result in a slight decline of image quality.

Field of view.
It
’
s mechanical possible to shift outside the recommended field of view, 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.
