I have been using the Olympus m4/3 RC (Remote Control) off-camera flash system for some time. It uses optical communication to control the outputs.

Now, I am getting a similar setup for my Sony Alpha A7R. That is via radio control (2.4 GHz) but is called Nissan Air System control.

Both systems are also referred to as "wireless" and both use a Commander flash.
