PLACEMENT OF LENS ON CAMERA

CABLE CONNECTION OF LENS CONNECTOR
The following configuration is common for mono- and varifocal lenses. If a bad connection occurs, both the lens and
camera may malfunction. Follow this figure very carefully.
PLACEMENT OF LENS ON CAMERA
To attach the lens to the lens mount, turn the lens clockwise on the lens mount until it reaches the end of the
threads. You can now turn the lens and lens mount
assembly on the camera counter-clockwise and clockwise
to easily adjust the back-focus and the lens-fixing position.
To take the lens off the camera, turn counter-clockwise.
The lens is a precision product. In case of breakdown,
please get in touch with your dealer or place of purchase.
We guarantee this product through one year after date of

LEVEL ADJUSTMENT
Sensitivity adjustment is made by the variable register marked
“LEVEL” on the lens body. By turning the screw clockwise
toward the “H”, the picture becomes brighter. The object’s
outlet image-signal changes according to its characteristics or
surroundings and can be readjusted by turning the LEVEL
screw.
NOTE: The Iris Control LEVEL has been adjusted by the
manufacturer and may not need to be adjusted for general
use.
NOTE: Adjustments must be done with the AGC switch “OFF”
for cameras with an AGC circuit.
ALC ADJUSTMENT
Picture Brightness
Adjust photometry using the ALC variable register on the lens
body. Turn the screw toward the “P” for peak photometry
(according to lighting) or the “A” for average photometry.
