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.
Read our Nikon D5100 Full Review

Vastly improved burst speeds with deep buffer; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video; Same great pocket-friendly design.
Pricey for a compact camera; JPEGs can look over-processed at higher ISOs; Lens doesn't offer as much telephoto reach; Battery life not as good as predecessor; 24-70mm-equivalent lens can feel limiting.
