Review Excerpt

  • Side-mounted tilt / swivel LCD screen; same sensor and processing as the Nikon D7000; good speed and battery life; in-camera HDR and filter effects; Full HD video capture with aperture control; audio levels control and external microphone jack.

  • AF-S lens mount doesn't offer autofocus with screw-drive lenses; popup flash isn't the greatest; no built-in wireless flash control; HDR function doesn't microalign source images.

  • Excellent image quality for an entry-level mirrorless; User interface ideal for consumers stepping up from point-and-shoots; Speedy and accurate autofocusing; Zoom lever on body; Tremendous value.

  • Lack of hot shoe or accessory port limits more advanced shooting; No electronic viewfinder; Performance lags behind previous model, especially on burst shooting speed.
