The speed of the zooming will be constant from the beginning to the end of this operation. This is different from
when the {ZOOM WIDE} or {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 RE-350 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.
