Optical viewfinder with nearly 100% field of view and approximately 1.05-times magnification
The PENTAX K-3 Mark III features an optical viewfinder with a nearly 100-percent field of view and a magnification of approximately 1.05 times. A newly developed, high-refraction glass prism assures comfortable viewing with a wide field of view equivalent to that of a full-frame SLR. Also, by using a distortion-correcting optical element and optimizing the lens coatings, it delivers a clear, true-to-life viewfinder image free of distortion.
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 systemPENTAX 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.
