E-TTL underexposure or overexposure:
 Suggest enabling wireless flash function when using E-TTL flash mode, and adjust the position of the flash, use
FEC/FEL function, check flash’s effective range.
 It may overexpose when E-TTL and manual flash are used at the same time; the manual flash suits being used as a
backlight.

whether you select "ALL", "A:B", "A:B:C" or disable Wireless function.

 Set compatible flash mode/shutter sync with the flash on the transmitter.
