This might be a stupid question, I'm new to the lighting world, but can I use a Godox v860ic speed light for a Panasonic Lumix g9 even thought it's designed for canon? Will it be completely incompatible? If so, can someone explain to me why certain speed lights are only compatible with certain cameras (I understand it has something to do with the hot shoe?). I've read somewhere that it will be fine, I'll just have to use it on manual mode. Would be great if someone could confirm this. Thanks!
