Sony has released a new app called Touchless Shutter that lets you trigger cameras without touching the shutter button, or anything else, at all. Instead of pressing the dedicated buttons, you can instead hold your hand over the camera’s eye sensor to expose a shot.
This method of starting an exposure can also be used when working in Bulb mode but two hand gestures are needed - one to start the exposure and another to end it.
Though the app is still in the beta phase, it has ensured the elimination of camera shake once and for all.
･Requires built-in or optional finder device with eye sensor. Pop up the finder when using this application with a camera model which has a pop-up electronic finder,
･Before launching the app, make sure the [FINDER/MONITOR] or [FINDER/LCD Setting] that toggles image display targets is set to Auto.
*1 This application supports bulb-shooting with: α7S and α7 II.
