The camera controls the Speedlite automatically in the following flash metering modes: 2.

During stroboscopic flash, the shutter should remain open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera . Far example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 sec. Calculating the Shutter Speed Number of flashes = Firing frequency (Hz) = Shutter speed 24 To avoid o\~~erheating and deteriorating the flash head, do not fire mare than 10 stroboscopic bursts.
