Superb image quality; Very high resolution; Surprisingly good high ISO performance; Fast autofocus; Compact, comfortable body with lots of customization potential; Bright, roomy and clear viewfinder; Tilting LCD display; Five-axis stabilization; Intuitive Wi-Fi / NFC connectivity
Movie button is poorly located; No touch screen; Not as fast to start up or shoot photos as a similarly-priced SLR; Rather slow buffer clearing; No built-in flash; Single card slot; Not weather-sealed to the same degree as some rivals
