When I am working I am carrying two and sometimes three EM5 cameras with FL600R flashes mounted. Using a Black Rapid strap, two cameras hang by my sides and sometimes I hang a third camera from my neck. I probably look like a one man Chinese fire drill! My system works very well for me and I am able to work fast EXCEPT for the settings on the flashes. The settings are being changed by rubbing against my body. I would place a piece of tape across the back of the flashes but I do make changes as I work. At this point, I need to replace the Fl600R flashes. I have Fl50s but they are too large for good balance. Soooooooo, does anyone have experience using a Metz or another similar flash with the EM5? Recommendations? One more thing, outdoor fill flash is iffy. Not at all like the FL50.
