On the quality of the flashes from the Metz home I do not have the lowest degree of doubt. I have some even already possessed, they were all great. Today I got - just for fun - my Canon flash EX 430 II placed on my Lumix FZ1000 and lo and behold, it works without any problems. So if you have multiple systems, already owns a Canon flash and also has a Panasonic / Olympus - think lightning, which should give it a try. Here you can probably save a lot of money.
