New firmware updates for the Sony Alpha α7R IV, α7R III and α7 III bring powerful flash control to the cameras. The addition of an external flash setting function allows you to configure the settings of an attached flash or Wireless Radio Commander (both sold separately) from the camera. Most settings, including light output, are accessible via the camera menu and changes are shown on the flash display. Wireless control of up to 15 flash units in 5 groups from the camera body or flash is available. The external flash control is available not only via the camera LCD screen, but also via the camera viewfinder. You can also assign flash control to a custom button for fast access and it also enables easy light output control for flash units that do not have control buttons.
