I was annoyed as my flash cable falls of the sync port all the time. On the other hand I was scared while shooting tethered I will fall over the cable and pull the cable out of the back. So I decided to use the “heavily” used accessory port. Originally this nice addon port is used by Hasselblad just for the GPS Addon. But I wanted to see some tiny addons here. For example a tripod mount for portrait mode or a cable mount. So I decided to make my own.
On the one hand you can fix the flash sync cable and on the other hand you can fix the tethered cable as well.
It is designed to use is with M3 and M4 screws.
