Review Excerpt

  • Superbly-built, comfortable and compact body; Pairs beautifully with pancake kit lens; Excellent image quality; Excellent performance in most respects; Great single-shot autofocus; Really nice viewfinder and touch-screen display; Friendlier user interface courts amateurs.

  • Some controls are a bit small and tightly-packed; Hand grips are still a bit modestly-sized for larger lenses; Continuous and video autofocus just isn't up to snuff; New user interface can feel limiting to advanced photographers; Underwhelming battery life.

  • 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.

  • Low-pass filter reduces fine detail from high-res sensor; High ISO performance isn't as good as some rival cameras; Video recording limited to 29:59.
