The Nikon D5100 is a 16.2-megapixel DX-format DSLRF-mount camera announced by Nikon on April 5, 2011. It features the same 16.2-megapixel CMOS sensor as the D7000 with 14-bit depth, while delivering Full HD 1080p video mode at either 24, 25 or 30fps. The D5100 is the first Nikon DSLR to offer 1080p video at a choice of frame rates; previous Nikon DSLRs that recorded 1080p only did so at 24 fps. It replaced the D5000 and was replaced by the D5200.
Automatic correction of lateral chromatic aberration for JPEGs. Correction-data is additionally stored in RAW-files and used by Nikon Capture NX, View NX and some other RAW tools.
Enhanced built-in RAW processing with extended Retouch menu for image processing without using a computer: D-Lighting, Red-eye reduction, Trimming, Monochrome & filter effects, Color balance, Image overlay, NEF processing, Quick retouch, Straighten, Distortion control, Fisheye, Color outline, Color sketch, Perspective control, Miniature effect, Selective Color, Edit movie, Side-by-side comparison.
EN-EL14 Lithium-ion Battery with up to 660 shots per charge.
The D5100 has no in-body autofocus motor, and fully automatic autofocus requires one of the currently 162 lenses with an integrated autofocus motor. With any other lenses the camera's electronic rangefinder can be used to manually adjust focus. It can mount unmodified A-lenses with support of the electronic rangefinder and without metering.
