PRIOR TO USE

INITIALIZATION WHEN POWER OF LENS IS TURNED ON
After the power for the lens is turned on, the lens must be initialized.

• The focus and zoom setting methods vary depending on the status of the respective servo/manual select knobs of focus and zoom of the lens when the power is turned on.
  1. When the knob is set to “Servo”: Both focus and zoom are automatically initialized.
  2. When the knob is set to “Manual”:
  Focus and zoom are initialized by turning each ring manually.
  When using a communication function such as LDS, always perform initialization. See the following table for the details of the initialization method.

• The iris setting method differs depending on the setting of the lens “function/mode changeover switch SW 1- 4″when the power is turned on, regardless of the setting of the iris mode changeover switch. (Refer to Page E13.)
  1. When set to ON: Initialization is automatically performed.
  2. When set to OFF:
  Initialization is performed by manually turning the iris ring.
  When using a communication function such as LIDS or controlling the iris from an external device, be sure to perform initialization.

INSTALLATION

INSTALLATION ONTO CAMERA
Note. Prior to installation of the lens, turn off the power o f the camera and, if used, the external power source.
WARNING Be sure to attach all the parts securely.
Dropping any parts from a height may cause severe accidents.

a. Take the rear lens cap off.
b. Rotate the mount clamp ring on the camera fully counterclockwise.
c. Fit the mounting surface of the lens to that of the camera, aligning the pin on the camera with a slot in the lens.
(The position of the pin depends on the model of the camera.)
d. Rotate the mount clamp ring fully clockwise.
Note. Make sure to adjust the flange focal length when installing the lens on a camera for the first time or installing it on another camera (refer to page E5).

ADJUSTMENT OF FLANGE FOCAL LENGTH

The flange focal length is the distance from the flange (mounting surface) of a lens to the focal plane.
Depending on the camera or conditions such as ambient temperature, there may be a case where the back focus is changed. If this occurs, perform the adjustment according to the following procedure.
■ CONDITIONS OF OBJECT AND DIAPHRAGM

1. Object: cut out the “Siemens Star” chart at the back of this manual and use it as the object
2. Distance of Object: about 3 meters
3. Diaphragm: open or as near to open as possible

■ ADJUSTMENT
For the operation of focus and zoom, refer to pages 7 and 8.
a. Loosen the F.f locking knob by rotating it counterclockwise.
b. Operate the zoom to set it to the wide end.
c. Rotate the F.f adjusting ring using the F.f locking knob to focus on the Siemens Star located approximately 3 meters away. The position where the radial black and white lines become sharpest is the optimum focus position.
d. Operate the zoom to set it to the telephoto end.
e. Operate the focus to bring the object into focus.
f. Operate the zoom to set it to the wide end again, and check that the optimum focus position adjusted in step is kept.
g. To adjust precisely, repeat the above steps ‘b’ through ‘f’ several times. (If the most optimum focus position usually holds in all zoom areas, the flange focal length is adjusted precisely. If it is not focused, the flange focal length is not adjusted sufficiently. In this case, start adjusting again from step ‘b.’
h. Finally tighten the F.f locking knob firmly.

IRIS OPERATION

There are two iris operation modes: auto iris mode and manual mode.
For the operating instruction in each mode, refer to the description on each mode.
Note. The auto iris mode only operates if the camera supports this mode. (The auto iris mode may not function normally due to the compatibility with the camera. In that case, use the manual mode.)
■ AUTO IRIS MODE
Set the iris mode select switch to “A.” The iris of the lens will automatically be adjusted responding t o the object brightness.
■ MANUAL MODE
a. Set the iris mode select switch to “M.”
b. Rotate the iris ring by hand to adjust the iris . Clockwise rotation of the ring causes the iris to move toward the closed side and counterclockwise rotation toward the open side.
Note 1. Although the iris operation mode is in Manual, the iris is adjusted automatically while the iris momentary switch is being pressed.
Note 2. The positions of the auto iris mode and the manual mode in the iris mode select switch can be interchanged by setting the iris A-M position change switch (refer to page E13) to ON.
When the positions are interchanged, apply the mode indication label, enclosed with the lens, onto the mode indication part of the lens so as not to cause confusion.
