Calibration
The focus motor can be used before calibration, but the range
that the focus wheel can rotate the motor will be limited. After
calibration, the focus wheel will be able to fully rotate the motor.
Calibrate Procedure
1. For lenses with a mechanical limit, calibration can be done
automatically. Press the focus wheel multifunction button
twice to calibrate the focus motor.

done manually. Press the focus wheel multifunction button
twice to start the calibration.

manually. The motor will continue to rotate and stop the
motor manually again when it reaches the start point.

Set Focus Motor Range
The range of the focus motor can be set by confirming Points
A and B on the focus wheel.
Rotate the motor to the desired Point A and press the focus
wheel multifunction button to confirm. After Point A is confirmed,
repeat the step to confirm Point B. Press the focus wheel
multifunction button again to delete Points A and B.
