Asked the manufacturer, they said that the Sony version won’t be produced in the future, but only Canon and Nikon version. Some ideas may meet your needs:
First, Sony A900/A850/A700 has PC port, these cameras can be connected to the the transmitter with a PC-PC cable, it will work as attaching to the hot shoe. But kindly note that and other Sony DSLR cameras doesn’t have PC port.
Second, use a YN-H3 adapter to connect the transmitter to the Sony hot shoe.
