Review Excerpt

  • 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.

  • 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.
