Olympus has provided two connection modes for the E-M1 that help to give a pretty clear insight into the way it expects the camera to be used. The first is a 'Private' mode designed for the camera's owner, which in concert with the Olympus Image Share app allows camera remote control, transfer of images to your smartphone, and geo-tagging of your images (using your phone to record a GPS track). The other is a one-time connection, to make it easy to share your images with other people's devices without them necessarily having to install the app.
