The 5.180.24.3/info/pentax" target="_blank">Pentax 5.180.24.3/info/k" target="_blank">K-5 is a 16.3-megapixel digital single-lens reflex camera, announced on September 20, 2010. It began shipping in mid-October 2010 and it was replaced by the 5.180.24.3/info/pentax" target="_blank">Pentax 5.180.24.3/info/k" target="_blank">K-5 II in the third quarter of 2012.
Externally, the camera body is almost unchanged from the 5.180.24.3/info/pentax" target="_blank">Pentax 5.180.24.3/info/k" target="_blank">K-7 (the mode dial on the left side is slightly higher). The main improvements compared to the previous model are higher light sensitivity (ISO range between 80 and 51,200, high ISO performance with improved noise control); an increase in sensor resolution by nearly two megapixels; and an all-new autofocus subsystem, SAFOX IX+.
The use of a Sony sensor in the 5.180.24.3/info/k" target="_blank">K-5 signalled a major departure from the Samsung sensor partnership.
The latest firmware release is 1.16.

DxOMark sensor tests


DxO Labs gave the 16.3 MP Sony-built sensor a score of 82. This ranked at the time of testing, the highest ever for an APS-C sensor and ahead of several full-frame sensors such as the one used in the Nikon D3. One of the major factors was shadow noise and dynamic range (in raw mode, to bypass in-camera processing). However, the closely related sensor in the Nikon D7000 scored 80.
