Review Excerpt

  • Superb image quality; Great high ISO performance; Rugged, comfortable camera body; Sharp articulating touchscreen display; Excellent AF point frame coverage; Fast continuous shooting speeds; 4K UHD video; Built-in Wi-Fi, NFC and Bluetooth.

  • Somewhat large for an APS-C camera; Expensive for a DX camera; 4K UHD video doesn't offer full DX field-of-view; No built-in flash; Still uses contrast-detect for Live View AF; Dual slots use two different card types (XQD and SD).

  • 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.
