This adjustment (distance between lens casing and sensor surface)
is required if a sharp definition cannot be obtained with the lens
focussing, or in order to adjust the ∞ position.
To obtain a sharp definition, point the camera at an object which is
at least 000 times further away from the front of the lens than the
focal length. (If the focal length is 7.5mm, the object must be at
least 5m distant from the camera).
Open the aperture fully and set the focus to ∞ (infinite).
If the lens has automatic exposure control, select a dark object,
or better use an ND filter (64-x) to ensure that the aperture is fully
open.
Undo set screw 1. Turn the lens with the CS mount connection until
the definition is sharp.
When finished, retighten screw 1.
To obtain a sharp definition, point the camera at an object which is
at least 5 times the minimum lens distance (MOD) of the lens. (If
this is m, the object must be at least 5m distant from the camera).
Open the iris fully and set the lens to the maximum tele position
and focus with the focus ring.
If the lens has automatic iris control, select a dark object (or use an
ND filter, 64-x) to ensure that the iris is fully open.
Set the lens to the maximum wide-angle position.
