Notes on auto focus
• The focus may not be easily fixed on the following
subjects. In such a case, manually adjust the focus:
– Subjects having very little contrast
– Subjects moving quickly
– Light sources, such as street lights or night scenes
– Subjects near an extremely bright thing
– Subjects through a glass window
• If there are multiple subjects both near and far from the
camera in the same picture frame, the focus may be fixed
on an unintended subject.
• If you zoom to a telephoto angle after adjusting the focus
while in a wide angle, the subject may become out of
focus.
• If you perform the zoom or iris adjustment after
adjusting the focus using the PUSH AF button, the depth
of field may become shallow, making the focus
insufficient. In such a case, press the PUSH AF button
again to bring the subject into focus.
• The auto focus function does not operate during zoom
operation.
• The auto focus function does not operate in SLS (Slow
Shutter) mode (selected on the FUNCTION 1 page of the
OPERATION menu).
Note on zoom speed
Depending on the shooting distance, zoom speed may
decrease when approaching the maximum telephoto
position.
