ZOOM TELE
} button on the front panel is pushed. If the {
ZOOM WIDE
} or {
ZOOM
TELE
} button is pushed and continues to be pushed for longer than one second, the zooming will increase to a
faster speed.
The

responds with a C-response data packet immediately after the reception of this command, but it is still
working on the Zoom control and
AF
adjustment.
