So it appears that no one buys the GH4 to shoot stills... In fact, I'm moving from an OM-D E-M5 to the GH4 to shoot 4K video. Just a fact of what I need at the moment. But, I'm a stills guy most of the time, and need an off camera wireless remote flash when I travel. The FL-600R has been fantastic, and the OLY interface to control is is a breeze. Yet I can find nothing on Panasonic options, short of the Panasonic DMW-FL360L Wireless External Flash manual and a YouTube unboxing. The stats are identical to the OLY FL-600R. The controls are identical. Are they the same unit? I don't want mount the OLY flash on the Panasonic GH4 out of fear of frying electronics. Is there anyone who can shed some light on this? Thanks!
