The E-M1 is the second Olympus to offer built-in Wi-Fi for connection to a tablet or smartphone, and expands on the E-P5's offering by adding more sophisticated camera remote control, alongside image sharing and geo-tagging. It's a pretty straightforward implementation, which means it avoids the complexity of Panasonic's labyrinthine, multi-function Wi-Fi that we struggled to fully utilize with the GH3. It's worth noting though that the E-M1 isn't designed with connection to a laptop in mind, instead its focus is exclusively on engaging with the smartphone you're likely to have in your pocket.
