If the flash exposure is correct, the flash exposure confirmation lamp lights for approx. 2 seconds. If the flash exposure confirmation lamp does not light there is a possibility that the picture was underexposed.
When shooting continuous flash exposures in manual flash mode, prevent the flash head from overheating by limiting the number of continuous flashes according to the power settings, as follows: 1/1, 1/ 2 power not more than 15 continuous flashes
