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
Attractive, retro rangefinder-style design; Improved (excellent) still image quality that's even better thanks to second generation X-Trans sensor technology; Great, sharp f/2 35mm-equivalent lens; Overall better operation and performance than the X100; Addition of phase-detect pixels makes bright light autofocusing faster.
Low-light AF slow and inconsistent; Video quality, even at 60p, compromised by moire and lack of image stabilization; Combined four-way pad/Command dial means AF control points cumbersome to change; Too easy to bump control dials and change settings accidentally (especially the EV dial).
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.
