This video post has two parts. One part is a pretty simple way of using the RF-603N Radio Flash Triggers (designed for Nikon or Canon Cameras), with any camera with a hot shoe. I have Panasonic and Sony mirrorless cameras and I’d rather have one solution that works with both manufacturers.
The second part is how to get any flash to work on the Sony a6000. The camera has a standard hotshoe, but no flash would work on the camera out of the box. There is a blogpost on this here.
