The Godox TT350o is fine, I use it on the G80. It's not very powerful, but good enough for small sized rooms [if you like to bounce] - might not be powerful enough for large group shots. I haven't got the X1T trigger for it yet, but i would suggest getting it to fire off cam - I have a larger flash with wireless triggers for when I need it but plan to get the Godox trigger at some point too. It's a lot neater and looks far better on a micro four thirds camera than a huge Yongnuo for example
