The Panasonic Lumix GM5 is an almost unthinkably small Micro Four Thirds camera with a 16MP sensor, 3" 921k-dot touch screen, 1080/60p HD video and built-in Wi-Fi. It follows in the already tiny footsteps of the GM1, adding a built-in EVF and more external controls to that camera's point-and-shoot approach. The GM5's enthusiast-friendly touches push it into a highly competitive category.
