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
The first genuinely compact--almost pocket-friendly--compact system camera, paired with equally small, interchangeable lenses. Great ergonomics for the size, and it feels like a real camera, not a computer with a lens.
Very restrictive lens selection at launch. All but two current lenses have severe limitations in functionality. Performance is sluggish, and image quality trails large-sensor cameras by some distance.
Advanced Wi-Fi and Near-Field Communications for easy image sharing and even remote shooting (a first for a waterproof compact); Improved ruggedness; Manual exposure mode; Fast cycle times; 10fps continuous burst shooting at full resolution; Full 1080p HD video at up to 60p; Excellent battery life.
Mediocre still image quality; Slow startup; Slower-than-average autofocus; Choppy MP4 (most Web-friendly format) video quality.
