Longer stills battery life

Cameras with longer battery life can take more photos before exhausting their batteries.

Review Excerpt

Superb still and video image quality; Powerful, fast, and accurate AF system with loads of cross-type points, loads of configurability and great frame coverage; Rugged, weather-sealed body with great control layout and user-interface configurability.
Dynamic range is limited by noise in deep shadows; Somewhat heavy-handed noise suppression and sharpening at default settings. (Shooting RAW avoids both.); No AF illuminator.
Read our Canon 5D Mark III Review

Pocket-friendly design; Unbelievably fast burst capture; Generous buffer depth, even for raw; Fast and confident autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video
Very pricey for a compact camera; Still no touch screen; Slow buffer clearing; JPEGs can look over-processed at higher ISOs; Lens doesn't offer much telephoto reach; Battery life is very modest; 4K movies are limited to five minute clips
