2-2 Back Focus Adjustment
If the relationship between the image plane of the zoom
lens and that of the television camera is incorrect, the object
goes out of focus when the lens is zoomed. Follow the steps
below to adjust the back focus of the lens.
1
Select an object at an appropriate distance
(UJ122x8.2BAF, UJ122x8.2B, UJ111x, UJ90x, UJ86x,
UJ66x: 10 to 15 m, UJ27x: 3 to 5 m, XJ95x, XJ80x:
10 to 15 m, recommended). Use any object with sharp
contrast to facilitate the adjustment work.
2
Set the lens to 1x [status without using an extender].
3
Set the iris fully open.
4
Set the lens to the telephoto end.
5
Bring the object into focus by focus operation.
6
Set the lens to the widest angle.
7
Loosen the F.B. lock knob, and then turn the F.B.
adjusting knob to bring the object into focus.
8
Repeat steps 4 to 7 several times, until the object
is brought into focus at both the widest angle and
telephoto ends.
9
After making sure that the object is in sharp focus,
tighten the F.B. lock knob.
NOTE
If your camera and lens support Remote Back Focus (RBF),
Back focus can be adjusted from the camera side. For details,
please contact the dealer where you purchased your camera.
