Reviewing the recording
It is possible to review the last few seconds of the
recording on the tape (recording review).
Press the VTR button to pause recording, then press
the RET button on the lens.
Depending on how long the button is pressed, the tape
is automatically rewound over the last two to ten
seconds from the paused position, and then this part is
played back in the viewfinder. If the RET button is
kept pressing, about ten seconds of the recording
review is possible.
The VTR then returns to the paused state.
Note
This function may not be provided by some VTRs.
Refer to the instructions for the VTR.
