Review Excerpt

  • Excellent image quality; High ISO performance improved over predecessor; Excellent burst speeds (up to 10fps); Significantly improved buffer depths; 65-pt AF system; Dual Pixel CMOS AF; Can focus down to f/8 (great for teleconverters); 1080/60p video; Headphone and mic jacks; Rugged build quality.

  • Autofocus speed (AF shutter lag) slower than 7D and 70D; Mediocre battery life for a pro DSLR; Dynamic range at low to moderate ISOs not as good as competitors; Phase-detect AF did not perform as well as expected in our low-light AF tests; No built-in Wi-Fi; No autofocus for 1080/60p video.

  • Excellent handling in a compact, weather-sealed body; Crisp, roomy electronic viewfinder; Image quality that can take the fight to APS-C DSLRs; Unique high-res mode lets it bat far above its weight for static scenes; Extremely fast 10 fps burst shooting, Excellent video feature set

  • Control dials are easily bumped; Below-average battery life at default settings; Buffer depths for raw shooters are a bit limited; 16-megapixel sensor resolution feels dated; Weak bundled flash strobe
