The Pentax K-5 is a 16.3-megapixel digital single-lens reflex camera, announced on September 20, 2010.^[1] It began shipping in mid-October 2010 and it was replaced by the Pentax K-5 II in the third quarter of 2012.^[2]

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 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 K-5 signalled a major departure from the Samsung sensor partnership.

The latest firmware release is 1.15.

Feature improvements

Consistent with previous Pentax models, there are many small improvements as well:

Multiple customizable "USER" modes
Customizable RAW/Fx button replaces previous single-purpose RAW button
Selectable noise reduction levels for each ISO value
More auto-bracketing options
1080p video (25 fps)
7 fps continuous shooting at full resolution
Bleach Bypass and Film Reversal image tone settings
Electronic level now shows pitch and roll
More grid overlays in live view mode

Notable features

Rechargeable Li-Ion battery D-LI90 or 6 × AA (R6) batteries in battery grip D-BG4
Magnesium alloy shell over stainless steel chassis, weather resistant with 77 weather protection seals. The K-5 is designed to operate at temperatures of −10 to 40 °C (14 to 104 °F).
Two-axis (roll and pitch) level meter
Automatic horizon correction up to 1° with SR on or 2° with SR off.^[3]
HDR (High Dynamic Range) function with auto-align now usable in hand-held shooting
SAFOX (Sensor Ability Fortifying Optical Compensation System-CS shortened to X) IX+ autofocus system that offers a choice of shutter-release options—between focus priority and release priority in the AF.S (single) advance mode, or between focus priority and speed priority in the AF.C (continuous) advance mode
Lens correction for lens distortion and lateral chromatic aberration in Pentax FA, DA and DFA lenses
The K_AF2 mount is compatible with all Pentax K-mount lenses made since 1975.

Video mode

The K-5 can record video at 1080p full HD as well as at lower resolutions using the motion JPEG codec. Videos can be recorded at the following resolutions and frame rates:

1920×1080 (25 fps)
1280×720 (25/30 fps)
640×424 (25/30 fps)

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.^[4]

Accessories

The weather-sealed D-BG4 battery grip that fit the Pentax K-7 can also be used on the Pentax K-5.
Pentax InfraRed Remote Control F or Wired Remote
Pentax AF-360FGZ and AF-540FGZ External Flash units
Pentax AF-160FC Flash Ring
Pentax GPS Module O-GPS1
