Flangeback adjustment
Flangeback adjustment is needed in cases where focus cannot
be obtained by normal lens focus operation or focus is lost at the
maximum telephoto and wide angle settings of a zoom lens.
In such cases, open the lens iris and adjust as follows.
Fixed focus lens
1) Set the lens focus ring to infinity.
2) Aim toward an object at least 20 meters distant.
3) Loosen the (2) lens mount screws and turn the lens mount
ring to adjust the focus. Use care not to disturb the lens
focus ring.
4) Tighten the lens mount screws.
NOTE
If using an auto iris lens and the adjustment object distance
is less than several meters, due to lens depth of focus
relationship, slight blurring can occur at certain iris positions.
In this event, darken the scene so as to open the iris and
adjust the focus or flangeback to prevent the blurring.
