• Offsets are subject to ±7% centering tolerance.
• % offset is defined as:
The horizontal position of the image can also be offset (moved to the left or right of the optical
center) by adjusting the lens mount. The amount of horizontal offset available depends on the lens
installed and if the image has already been vertically offset. Horizontal offset can be expressed as
the percent of half the image width or the number of pixels of shift to one side of lens center.

In this example, no offset is applied.
Therefore, half of the image appears to the
left of lens center and half appears to the right.
In this example, 50% offset is applied.
Therefore, 3/4 or 75% of the image
appears to one side of the lens center.
