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

Compact DSLR camera body; Excellent image quality; Reliable single-shot autofocus; Good continuous JPEG shooting performance; New kit lens has improved AF; Great value at current prices.
SnapBridge is slow and limited; Poor continuous autofocus; No built-in Wi-Fi; Mediocre video features.
