I am Primarily an Underwater photographer, but recently bought this above water flash. It has version 2.0 firmware and works well with the OM-D EM-5. The challenge is the documentation shows the ability to turn the three beam AF light on and off on the flash, but that option is not there, and I cannot make it work. At all. Thanks in advance if anyone can share some feedback as to getting it working! I have changed all the other modes and such to see if it comes available, but no luck.
