The adapter plugs into the flashbar slot and provides a x-sync standard pc socket where you can connect any electronic flash or radio remote.
The sync voltage can be 3 - 300 V so new and old flashes work.
The flash side is completely isolated from the camera side.
Price for one adapter is 50 US$ or 45 Euros shipped worldwide.
I know this is a lot of money for such a small device.
I could probably have them produced in China for one dollar and sell them for five if I ordered 20'000 pieces.
However the market is not that big so I assemble each one by hand, even machine my own pc sockets.
I spend about 1 hour on one adapter, not counting development and user support.
You can try the adapter and return it if you have any reason to do so.If you would like to buy a flash-adapter send me an e-mail. firstname.lastname@example.org
Here are some exemples of photos shot with the adapter.
