Review Excerpt

  • Very fast top frame rate; full-time phase-detect autofocus; Full 60p HD video; Excellent kit lens; Very good high-resolution sensor.

  • Heavy; EVF appears dim when used in bright light; AF tracking in Movie mode was unreliable in our testing.

  • Highest resolution Canon APS-C camera yet; Great image quality; Faster 10fps burst shooting; Very fast autofocus; Dual Pixel CMOS AF in Live View; 4K video; 1080p120 slow-mo video.
