Tethering shooting with a Sony Alpha 7RIII

This is a new safe method for the Tethered Shooting with Sony A7III, and  A7IIIR3, as well as for models of other manufacturers that support USB 3.1 type C.

There is no risk of damaging the USB 3.1 Type C port with this method!

All you need is a 10-pin USB-C data cable with magnetic contact.
The transfer of the ARW (RAW file) with approx. 42MB takes less than one second.

Tethering is an extremely helpful and beneficial function of modern digital cameras. With nature or material photographs, it is possible to design the photo before the actual photograph takes place. The photos are viewed in detail in live mode on the connected Mac/PC while the camera is on a tripod and connected to a computer. The essential difference to the classical method is the following:

With the new USB 3.1 Type-C magnet/data cable, the camera board can no longer be damaged if the cable is unintentionally torn out.
The repair of the board is horrendously expensive!

Magnetic 10pin Cable:                                                      

If the Laptop/MacBook does not yet have a USB 3.1 type C, a connection via an adapter (USB 3.1 type C plug to USB 3.0 type A) is possible too.

working method: 

  • Download the latest version of Sony Remote Control
  • Set the camera’s menu settings (menu 4) to USB Connection – PC Remote.


  • Connect the USB-C magnetic cable to the Mac/PC.
  • Launch „Sony Remote Camera Control“ software

This cable can even charge the camera with a power bank.

However, I did not test the quick charging of the camera with USB-C Power Delivery, but instead used an adapter plug (USB 3.1 Type-C plug to USB 3.0 Type A).
