Nikon D5200

The Nikon D5200 is an F-mount DSLR camera with a newly developed 24.1-megapixel DX-format CMOS image sensor first announced by Nikon on November 6, 2012 for most of the world and January 7, 2013 for the North American market.
The Toshiba TOS-5105 (HEZ1) APS-C CMOS Image Sensor features 14-bit resolution NEF (RAW) and ISO 6400, expandable to 25,600. The D5200 integrates the same Multi-CAM 4800DX autofocus system as the D7000. The camera replaces the D5100 and is replaced by the Nikon D5300.
Initially, the camera was available worldwide except in North America. While Nikon officially announced the D5200 in Europe, Asia, and Australia in November 2012, Nikon's U.S. operating company did not initially announce the camera, and did not update its website to include this model. The official North American launch came during the CES show in Las Vegas, on January 13, 2013.
Feature list.
Like Nikon's other consumer level DSLRs, the D5200 has no in-body autofocus motor, and fully automatic autofocus requires one of the current 162 lenses with an integrated autofocus motor. With any other lenses the camera's electronic rangefinder (which indicates if the subject inside the selected focus point is in focus or not) can be used to manually adjust focus.
The D5200 can mount unmodified A-lenses (also called Non-AI, Pre-AI or F-type) with support of the electronic rangefinder and without metering.
Firmware update.
Nikon released a firmware update Ver. 1.01 for the D5200 on 14 November 2013. The update added support for EN-EL14a Rechargeable Li-ion Battery in the D5200. Another firmware update Ver. 1.02 was released on 21 January 2014 adding support for retractable lenses and providing bug fixes. Firmware Ver. 1.03 was released on 15 Sep 2015 fixing issues related to video framerate, and sensor cleaning bugs.
