I am new to underwater strokes. My Meikon housing has two fiber optical ports, and it is designed to fit Canon EOS M and an optional 90EX flash. EOS M itself does not have a built-in flash.
According to the description, "YS-03 is compatible with any camera containing a pre-flash and a TTL flash exposure function." I understand it is designed for most point and shoots with built-in flash.
I assume EOS M + 90EX combo can meet YS-03's requirement? 90EX supports eTTL and can be used as a wireless master to fire off my 270EX and 580EX. If it would work, what setting should i use for camera and 90EX?
Thank you very much.
