Cameras with longer battery life can take more photos before exhausting their batteries.
Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
AF speed vastly improved; Increased continuous frames per second (JPEGs at 12.5fps vs 10fps in G15); Solid build and ergonomic, comfortable feel; Excellent f/1.8-2.8 5x optical zoom lens; Advanced photographic features, including PASM dial and RAW capture; Dedicated ISO button; Customizable buttons; Excellent macro mode; 1080p/60fps Full HD video.
LCD screen not articulated; Larger design makes it not very pocketable; Optical viewfinder not very accurate; RAW burst shooting still slow; Wi-Fi is clunky to set-up & no remote shooting capabilities; No built-in GPS.
Smaller, lighter body than flagship X-T1; Plenty of external controls; Bright and high-res electronic viewfinder; Great still image quality even at high sensitivity; Good all-around performance; Capable Wi-Fi remote control; Good kit-lens options
Handgrip is rather shallow; Movie button is hard to press; JPEGs have limited dynamic range by default; Indoor white balance tends rather warm; Limited burst depth even for JPEG; Penalizes early shutter button press; Movie image quality lags the competition
