Review Excerpt

  • Phenomenal resolution and detail; Great high ISO performance; Rugged, weather-sealed body; Huge, bright viewfinder; Fast autofocus works well in low light; Swift performance for a medium-format camera; Good battery life; Shoots Full HD video

  • Quite bulky compared to an APS-C or full-frame DSLR; Autofocus points clustered near center of frame; Most lenses aren't weather-sealed or optimized for digital; Prone to aliasing artifacts (but so are most high-end cameras these days); Attracts a lot of attention from passers-by

  • 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.
