Longer stills battery life

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

More dynamic range

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

Excellent image quality; Improved high-ISO performance; Better JPEG quality; Fast autofocus; Very good subject tracking with real-time live view feature; All-magnesium body construction; 4K video.
Slow buffer clearing (no UHS-II support); No touchscreen, Clunky menus; Wi-Fi can be a bit frustrating to use.
