A:Answer Hi Archie, Sony's commitment to customer satisfaction is our top priority. The iOS app cannot be used while streaming. Only the settings on the camera can be used while streaming. If you assign the shutter speed, ISO sensitivity, etc. to the control wheel or register them to the function menu, you can adjust these values even during USB streaming. When you set [Zoom Setting] to [Digital Zoom], you can use this zoom function. Yes the zoom will go past the 70mm optical range only when the setting is set to Digital Zoom.
