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.

  • Faster overall; Very good image quality; Generous 7.1x zoom range; Good controls; Tilting VGA LCD; RAW support.

  • Video limited to 720p24; Other cameras are still faster in some areas; LCD tilts only up or down, not side-to-side; Sub-command dial turns too easily.
