Overview

K-3 Mark III (Body)

PENTAX believes in the future of SLR photography.
As the pioneer of SLR cameras in Japan, PENTAX has devoted all its assets — its philosophy, technologies and passion — to the development of this remarkable camera. The PENTAX K-3 Mark III: the new flagship of the APS-C-format SLR lineup.

High-performance viewfinder

Optical viewfinder with approx. 100% field of view, and approx. 1.05X magnification. The PENTAX K-3 Mark III features a high-performance viewfinder with a high-refraction glass pentaprism to provide approximately 1.05-times magnification (with an FA 50mm F1.4 lens set at infinity). Despite the compact, lightweight APS-C-format SLR body, it delivers a truthful, wide-view image equal to that of a full-frame SLR, and helps you to become more fully immersed in the photo-shooting process.

This viewfinder also provides an almost 10-percent increase in brightness, thanks to the improved reflectance of the pentaprism, while also assuring a nearly 100-percent field of view. By incorporating a distortion-compensating optical element and optimizing the lens coatings, it provides natural, true-to-life image rendition with high-magnification observations.

High-speed drive system

High-speed drive, with a maximum speed of approximately 12 images per second. Thanks to the combination of a newly developed mirror and shutter driving unit and the high-speed, high-performance PRIME V imaging engine, the PENTAX K-3 Mark III provides a high-speed drive system with a maximum speed of approximately 12 images per second in the AF.S mode, or approximately 11 images per second in the AF.C mode. This system lets you capture a momentary expression of the subject, which couldn’t otherwise have been captured by previous models.

High-precision autofocus system

SAFOX 13 AF system with 101 focus points

The number of focus points in the PENTAX K-3 Mark III have been increased to 101, from 27 in the PENTAX K-3 II. The AF area also has been greatly expanded. Of 41 user-selectable points,* 25 are cross-type sensors. This high-density AF system enhances the flexibility of image composition, while optimizing focusing accuracy on the subject. Since its middle focus point is designed to detect an F2.8 luminance flux, the camera assures super-high-precision focusing when using a bright lens with an open aperture of F2.8 or larger.

SR (Shake Reduction) mechanism

SRII for five-axis, 5.5-shutter-step camera shake compensation

The PENTAX K-3 Mark III’s SR II mechanism compensates for camera shake caused by horizontal and vertical shift, roll, pitch and yaw, with a wide compensation range up to approximately 5.5 shutter steps. In addition to the all-purpose Auto mode, this mechanism also provides a Panning mode to capture slow-moving subjects. You can choose the mode that provides the ideal compensation effect for your subject.

Smart Function

More versatile Smart Function

The PENTAX-original Smart Function provides easy, single-action selection of menu items and functions. Featuring a new Smart Function button, the PENTAX K-3 Mark III now lets you preprogram a maximum of five functions from 22 options, and displays a list of the selected functions in the viewfinder window, so you can select the desired function without removing your eye from the viewfinder. It even lets you select and program the desired values for each function, allowing you to more precisely customize this function to meet your preferences.

Rugged construction

All-surface magnesium-alloy body

The PENTAX K-3 Mark III’s top, bottom, front and rear panels are all made of magnesium alloy. This lightweight, high-rigidity material not only protects the camera’s internal mechanisms from shock and vibration, but also creates the look of a solid, high-grade camera body.
