Well, I wonder if there are others with an EL5 and R5ii.I noticed I got a lot over exposure shots, and was trying to figure out why. Now I found it. It seems when you click the flash down, it will go full power! even at iso100 F5.6 is get fully over ...
All the extra testing isnt really needed. It's been confirmed by a friend who also has an R5ii and R3 and EL5, who can replicate the issue. On the R3 it's fine, but on R5ii, its overexposed when clicked down.
