CONNECTION/INSTALLATION
Back focus adjustment
Be sure to make back-focus adjustments when changing the lens
mounting 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. (
੬ Page 27)
● The auto iris lens may operate under extremely bright condi-
tions (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 enter-
ing 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.
