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.
