Miops Mobile mounted on Z 9 (required cable not pictured)
I am a HUGE Miops fan, I love their products! When I saw the RemotePlus Trigger or Miops Mobile come to market, I instantly got one. Just like their products, Miops simply states about the Mobile:
Leave the control of your camera to your Smartphone!
MIOPS RemotePlus is a high-speed smart camera trigger which is controlled by smartphone application. It can be used for remote shooting, timelapse, HDR photography and lightning photography. It enables your DSLR and mirrorless cameras to capture high-speed photos triggered by sound, light or when any objects break the laser beam.
All I can add is, GO GET IT!
