... Rapid charge and discharge circuits (FC1, OUT9, and OUT10) The SH control block (OUT9/10) includes rapid charge and rapid discharge circuits to support burst (rapid sequential) imaging. Since this type of circuit is not included in the AE control block (OUT11/12), the OUT9/10 block must be used for shutter drive. LB8649W Output INHD OUT9 OUT10 OUT11 − ...

... For the above reasons, especially if high-speed shutter drive is required, the value of the capacitor connected to the FC pin should as small as possible as long as the output does not oscillate (the range roughly from 0.0015 to 0.033 µF).
