Ensure that the motor torque level matches the lens to avoid lens
damage. Stiff, hard-to-move lenses require a higher torque level.
Torque setting is not available for the CLM-2 motor.
Press CAL ALL to calibrate all motors.
Press CALIBR. to calibrate the current lens motor.
Manual Calibration of Lens Data Encoder LDE-1
To manually calibrate a Lens Data Encoder LDE-1, proceed as follows:
Attach the LDE-1 to the lens and connect it to its respective motor
connector on the UMC-4 (e.g. if it encodes the focus scale, connect it to the
FOCUS motor socket).
Press CALIBR. or CAL. ALL to activate calibration mode. Turn the encoded
lens scale to its limits. After reaching both limits, leave the lens encoder still
for at least three seconds. The motor status will change from
Calibrating
to
Calibrated
. The calibration is now completed.
Note: The
Side
setting for lens motors and lens data encoders refers to
mounting on standard support rods on the bottom of the camera.
Note: The
Side
setting for the LDE-1 lens data encoder refers to mounting
it with the tying knob facing away from the lens.
