Sony has released a new release cable, the VMC-MM2 which is designed to interface between the RX0 and any other Sony α or Cyber-shot camera.
Using the cable, the RX0 will automatically take a photo or start/stop video recording in sync with the main camera being used. You may be wondering why you would want to do this but it is quite a common set up for those capturing behind-the-scenes footage or POV footage for photojournalists.
If both cameras were set to the same mode you would expect them to start and stop recording at the same time but it’s unclear of how the two cameras will function if they are in different modes, i.e. main camera to take stills and the RX0 set to record video footage.
The new VMC-MM2 will ship in Europe in April, 2018 priced at approximately £50/€55.
