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.
Excellent image quality; Solid, weather-sealed body; Retro design that actually makes sense in a digital camera; Very low viewfinder lag for single-servo shooting; Fast burst shooting with great buffer depths; In-camera Wi-Fi connectivity
Exposure compensation dial is easily bumped; Four-way controller buttons are hard to press; Significant viewfinder lag for burst shooting; No raw files above ISO 6,400; Default settings strongly limit JPEG dynamic range
