(4) Inspection of lens-servo time
Make this inspection on both focal length 70mm (W) and 300mm (T).
Select the servo
driving amount respectively. Each lens-servo drive time must be within the standard.
Caution
:
If the MF ring is rotated during inspections, the waveform shows an abnormal value. Do NOT touch
the MF ring during inspections.
This inspection must be made at the following 5 lens positions with the focal length [both 70 mm (W)
and 300 mm (T)].
