I just purchased a metz 58 af-2 to use on my e-m1. The problem is I can't get it to fire when on the camera. If I set it to RC mode and the metz to slave (off camera) I can get it work, using the pop up flash on the camera. I'm by no means an expert with flash but I have never struggled to get one to fire. I upgraded firmware, made sure RC was off and even tried manual flash mode. On the flash I tried ttl, auto and manual, still nothing. The flash registers the zooming of my lens and the camera shows the lightning bolt icon, but nothing. I'm thinking the flash is faulty, but wanted to see if anyone has any ideas. Thanks in advance.
