Back focus adjustment

Be sure to make back-focus adjustments when changing the lens mount-
ing method or using a different lens.
● To make accurate back focus adjustments, carry out adjustments in
a state where the lens iris is released.
To open the lens iris, set MODE in the FOCUS ADJUST menu screen
to ON. ( Page 27)
● The auto iris lens may operate under extremely bright conditions
(7000lx or higher). In this case, use an ND filter to adjust the amount
of light.
(The ND fiter acts to reduce the amount of incident light entering the
lens evenly over the entire wavelength band.)

Memo
If the iris cable length of the lens is insufficient when turning the
back focus adjustment rings, lock the back focus locking screws,
turn the lens and loosen the back focus locking screws again for
achieving back focus.
