Adjustment of flange
focus for fixed focus
lenses
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 2000 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 15m 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.
