Focusing/Control ring
Delayed focus may occur if the focusing ring
z
(focusing/control ring) is quickly turned.
Due to the structural characteristics, the focus
z
lens driving speed may vary according to the
variation in the air temperature and posture.
Do not touch the operating part in the front of
z
the lens while the focus lens is operating. If
external pressure is applied to the moving part,
the lens initialization may be performed to return
the focus lens to the correct position for control
purposes.
Setting the focus mode/control selector switch to
z
CONTROL will fix the focus mode as AF. Table*4
However, depending on the camera used, it is
possible to switch the focus mode to MF on the
camera. Table*5
Please refer to the camera's instructions for
details.
The lens' focusing ring (focusing/control ring) is
z
electronic.
It is possible to set cameras that support
z
electronic fulltime manual focusing to manual
focusing when the camera is in the operational
mode. However, the camera settings need to be
changed.
When AF operation is set to One-Shot AF,
z
manual focus is possible after autofocusing
has been completed by continuing to press the
shutter button halfway (electronic manual focus
function). However, the camera settings need to
be changed.
When movie recording, the AF speed will be
z
slower than the still photo shooting mode. It is
possible to adjust the AF speed on the camera
by setting Movie Servo AF to [Enable].
Please refer to the camera's instructions for
details.
