The Pixel Hotshoe adapter TF-334 is made to provide your Sony MI camera which has a new MI (Multi Interface) hot shoe connection with a Canon or Nikon accessory.
Use Pixel Hotshoe adapter TF-334
You can use the hot shoe adapter for all Sony cameras with the MI hotshoe connection. The TF-334 adapter also has an x-contact, with which you can control your studio flash(s) in combination with a synchronization cable.
The TF-334 does not transmit a TTL signal from the camera to the accessory, only the middle contact is used. As a result, a speedlite will be triggered, for example, but it will have to be set manually (in terms of power, etc.).
