The familiarity of a full-frame SLR meets updated technology in the Pentax K-3 Mark III DSLR camera. With a 25.7MP BSI CMOS sensor, a high-density 101-point AF system, a distortion-correcting optical element, and an advanced SR II Shake Reduction System, the Pentax K-3 Mark III is a staple in Pentax's APS-C lineup.
High-resolution images assured by approximately 25.73 effective megapixels and super-high-sensitivity photography at a top sensitivity of ISO 1600000
The PENTAX K-3 Mark III is equipped with a back-illuminated CMOS image sensor with approximately 25.73 effective megapixels. By coupling this sensor with an AA (anti-aliasing)-filter-free optical design, the camera produces super-high-resolution images. The newly developed, high-performance PRIME V imaging engine and new-generation accelerator unit delivers well-defined images with minimal noise, while retaining high-resolution reproduction at all sensitivities — even in the super-low or super-high range. By greatly improving the noise-reduction performance at high-sensitivity ranges, it boasts a top sensitivity of ISO 1600000 to extend the range of scenes that can be photographed
In-body SR mechanism, compatible with all mountable lenses*
The built-in SR II shake-reduction mechanism effectively minimizes camera shake and delivers sharp, blur-free images, even in camera-shake-prone conditions. In addition to horizontal and vertical camera shake caused by pitch and yaw, this five-axis mechanism compensates for camera shake caused by horizontal and vertical shift (often generated in macro photography) and camera shake caused by roll. It assures a compensation effect of approximately 5.5 shutter steps（CIPA standard compliant, HD PENTAX-DA 16-85mm F3.5-5.6ED DC WR、f = 85mm） — the highest level in PENTAX history — to expand the limits of handheld photography. This mechanism also provides a new Panning mode to capture sharp, clear images of slow-moving subjects.
*This mechanism is compatible with K-, KA-, KAF-, KAF2-, KAF3-and KAF4-mount lenses, and also with screw-mount and 645- and 67-system lenses using an adapter. Some functions may not be available with certain lenses.
Pixel-Shift Resolution System
This innovative system captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizes them into a single composite image. Compared to the conventional Bayer system, in which each pixel has only a single color-data unit, this system obtains all color data in each pixel and delivers super-high-resolution images with more truthful colors and much finer details than those produced by the conventional system
PENTAX Real-time Scene Analysis System, supported by the latest artificial intelligence technology
Supported by the combination of the new, high-density RGBIr image sensor and the high-performance PRIME V imaging engine, the PENTAX Real-time Scene Analysis System instantly detects the subject’s face and eyes using the advanced image recognition technology, then makes real-time analysis of their movement. This assists the camera in optimizing exposure settings and improving autofocusing accuracy. By adopting Deep Learning — the latest, much-publicized artificial intelligence technology — the PENTAX K-3 Mark III assures more accurate subject detection and more reliable scene judgment.
Compact, sturdy body with dustproof, weather-resistant construction
The PENTAX K-3 Mark III’s top, bottom, front and rear panels are all made of lightweight, high-rigidity magnesium alloy. Coupled with a dustproof, weather-resistant construction with special seals applied to crucial parts of the camera body, and outstanding cold-resistant performance to ensure stable operation at -10°C, the camera is designed to be extremely durable and dependable even in harsh environmental conditions. The camera also features a durable, dependable shutter unit — verified in an endurance test of 300,000 shutter-release actions — to perfect the rugged body for worry-free shooting at any location.
4K-resolution movie recording with a range of functional settings
The PENTAX K-3 Mark III captures 4K-resolution movie clips (3840 x 2160 pixels; 30p/24p frame rate) or Full HD movie clips (1920 x 1080 pixels; 60p/30p/24p frame rate) in the H-264 recording format. Equipped with a stereo microphone input terminal and headset terminal, it also allows the user to manually set the audio recording level and monitor the sound pressure level for microphone input. Thanks to quiet touch-screen control on the LCD monitor positioned on its back panel, the desired shooting function and exposure compensation level can be set without worrying about operational noise.
