8.2 Configuring the lens, shift

What can be done?
The image can be optically shifted by using the vertical and horizontal lens shift.
If you want to reach a lens shift beyond what is possible with the optical shift, you can also perform a digital
lens shift. This digital shift will occur on the DMD, rather than the lens holder. So take into account that this
additional shift is minimal and restricted to the limits of the chip used.
For the digital zoom and shift, navigate to Home → Image → Digital Zoom Shift. For more info, see "Digital Shift
& Zoom", page 67.
Optical lens shift is only possible when the used lens has been fully calibrated. To calibrate the lens,
navigate to System Settings → Maintenance → Lens Calibration.
Vertical and Horizontal Shift
1. In the main menu, select Installation → Lens → Shift.
