The number of flash firings is the maximum number of times the Speedlight fires •
when the camera’s shutter is open. This number cannot be achieved with a high
shutter speed and low flash firing frequency.
The maximum number of flash firings differs depending on flash output level •
and flash firing frequency. See the table below for the maximum number of flash
firings.
