Without battery: 670 grams (1.5 lb)The Pentax K-5 is a 16.3-megapixel digital single-lens reflex camera, announced on 20 September 2010.[1] It began shipping in mid-October 2010.
Externally, the camera body is almost unchanged from the Pentax 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 51200, high ISO performance with improved noise control); an increase in sensor resolution by nearly two megapixels; and an all-new autofocus subsystem, SAFOX IX+.

- 1920x1080 (25p)
- 1280x720 (25p)
- 1280x720 (30p)
- 640x424 (25p)
- 640x424 (30p)
DxOMark sensor tests
DxO Labs gave the 16.3 MP Sony-built sensor a score of 82. This ranks 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. [3]
It should be noted that these scores purely represent sensor quality and not camera features and performance or JPEG quality.
