I'm using the Nissin i60a with my X-T2. I'm wondering how metering modes, and especially focus point affect the flash metering. If I understand correctly, the Nissin uses a preflash to determine the correct amount of flash (ETTL). But does it use the metering mode (Spot, Average, Center Weighted) that the X-T2 is set to and the focus point that the camera is set to (single or multi). Any explanation or pointers to resources on this greatly appreciated.
