The new standard of the 35mm full-frame K series

Rich colours and subtle shades, beautiful bokeh and a well-defined sense of depth. When the photographer's inspiration is reflected in all these elements, photographs will become more than mere records - they will evolve into truly impressive works of art.

The PENTAX K-1 Mark II has been created as the flagship model to fulfil this goal. It features a new, advanced image-processing system to deliver the beautiful image quality which all photographers demand. It produces images that are rich in colour and gradation, high in resolution, and superb in bokeh rendition.

The Pixel Shift Resolution System II - the PENTAX-original super-solution technology - now accommodates handheld photography. The AF system featuring a new algorithm assures high-precision focusing even with moving subjects.

While inheriting the PENTAX K-1's development concept, the PENTAX K-1 Mark II has advanced technologies to near perfection. When your creativity is in complete harmony with the camera, your photography will truly come alive.

State-of-the-art imaging processing system

Greatly improved image quality, even in high-sensitivity photography

To reproduce lively colors and rich gradations close to memory colors in all sensitivity ranges, the PENTAX K-1 Mark II newly incorporates an original accelerator unit, which efficiently processes image signals output by the image sensor before sending them to the imaging engine. This process upgrades both image resolution and color reproduction in a high-sensitivity range, while drastically reducing noise compared to the PENTAX K-1. It also helps bring the camera's top sensitivity up to ISO 819200 (at standard output sensitivity) for high-grade, super-high-sensitivity photography. Top sensitivity of ISO 819200 enhances image quality, and expands the creative boundaries of high-resolution digital SLR photography State-of-the-art imaging processing system Greatly improved image quality, even in high-sensitivity photography

High-performance imaging engine to assure high-resolution image reproduction

The PENTAX K-1 Mark II's PRIME IV imaging engine is the culmination of PENTAX's high-speed, high-quality image processing technologies. In addition to highly efficient noise processing, it features Fine Sharpness and Extra Sharpness functions to process the subject's outlines more naturally and more delicately, and the PENTAX Real-time Scene Analysis System, which has adopted a breakthrough deep learning technology. It also effectively compensates for the distortion, vignetting and chromatic aberration caused by specific lens properties, while efficiently correcting the fringe effect.*
*Available in combination with D FA-, DA-, DA L- and FA-series lenses. Some of these lenses may not be compatible with these functions.

A large, high-performance image sensor to capture all lighting data

The PENTAX K-1 Mark II's 35mm full-frame image sensor features a large imaging area and a wide pixel pitch to deliver lively, true-to-life images with rich gradation. It also assures superb noise reduction performance to capture the subject truthfully with fine details and subtle shades. Its shallow depth of field allows you to control the sense of depth and bokeh (defocus) effect at will.

AA-filter-free design to optimise resolving power

The PENTAX K-1 Mark II features an AA (anti-aliasing)-filter-free design to optimize image resolving power. This design produces true-to-life images by faithfully depicting the fine details of the subject. It retains excellent resolution, even when the image is cropped during shooting, or the captured image is trimmed during processing. It allows you to capture the decisive moment in a sharp, clear image.

The advanced Pixel Shift Resolution System II for super-high-resolution images

A PENTAX technology to produce high-quality images beyond the power of total pixels

PENTAX's Pixel Shift Resolution System II* is the super-solution technology which realizes image resolving power and color reproduction far better than that of the conventional Bayer system. By taking advantage of the camera's SR mechanism, it captures four images of the same scene by slightly shifting the image sensor for each image, obtaining all RGB colour data and luminance data from each pixel, and then synthesizing them into a single, super-high-resolution composite image. It not only improves image resolving power, but also prevents the generation of false colour, reduces high-sensitivity noise, and greatly improves image quality.

* When using this system, the user is advised to stabilize the camera firmly on a tripod during shooting, set the drive mode to self-timer or remote control, or use the mirror lock-up function.

** The desired effect may not be obtained when the subject is on the move or a camera shake occurs.

Innovative Dynamic Pixel Shift Resolution mode

Greater flexibility in handheld shooting

In addition to conventional shooting modes, the Pixel Shift Resolution System II features a new Dynamic Pixel Shift Resolution mode*, an innovative technology that takes advantage of slight fluctuations of the subject's position during handheld shooting. The camera closely analyzes four captured images and detects camera shakes during the handheld shooting before synthesizing them into a super-high-resolution composite image.** By combining this mode with the camera's SR mechanism, you can use the advanced Pixel Shift Resolution System II with more flexibility, even in difficult shooting conditions such as shooting at poorly lit locations or without using a tripod.

* When using a tripod, the user is advised not to activate the Dynamic Pixel Shift Resolution mode.

** Captured images may not be properly synthesized with certain subjects or under certain conditions. By capturing images in the RAW or RAW+ format, the user can process the images unsuitable for the synthesizing process as normal RAW-format images within the camera body.

SR II in-body shake reduction mechanism 

Five-axis, five-shutter-step camera shake compensation

The PENTAX-original sensor-shift-type shake reduction mechanism has been upgraded to provide optimum compensation for all lenses used in handheld shooting. The new-generation SR II (Shake Reduction II) features a five-axis mechanism to compensate for camera shake caused by horizontal and vertical shift* (often generated in macro photography) and camera shake caused by roll, which is difficult to handle by lens-installed shake reduction mechanisms, in addition to more common camera shake caused by pitch and yaw.

The SR II unit is controlled with great precision as soon as the camera's power is turned on and provides a wide compensation range - as much as five shutter steps** - to expand the limits of handheld shooting.

* During Live View shooting, this mechanism does not compensate for camera shake caused by horizontal and vertical shifts.

**Measured in conformity to CIPA standards, using an HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR lens at a focal length of 105mm.

High-precision AE/AF operation at -3EV illumination

Extra-accurate auto-exposure and autofocus control, even in the dark

An illumination level of -3EV makes it difficult to see a subject with the naked eye, and almost impossible to make accurate focus with manual focusing. Even under such low-illumination conditions, the K-1 Mark II assures high-precision auto-exposure and autofocus operations.*

Thanks to its upgraded algorithm, its autofocus response time for poorly illuminated subjects is greatly reduced. Coupled with its super-high-resolution imaging power, the K-1 Mark II delivers exceptional shooting performance in dark locations.

* Light metering measured at ISO 100 and with a 50mm F1.4 lens; focusing measured at ISO 100, at room temperature and with 25 middle sensors.

Outdoor-oriented monitor with red-lit monitor display function

Easy, pushbutton control of monitor brightness

The camera's outdoor-oriented monitor, which provides an easy setting of the brightness level, has been upgraded. In addition to positive settings to assure the correct brightness level in bright locations, it now provides negative settings to improve visibility in dark locations.

It also features a red-lit monitor display function to facilitate monitor viewing when your eyes have become accustomed to a dark location during astronomical or nighttime photography.

By assigning this function to the Fx1 button, you can instantly switch the monitor display between the normal and red-lit modes.

Dependable dustproof, weather-resistant construction

A completely environment-resistant imaging system, with a weather-resistant lens

A combination of the K-1 Mark II's 87 sealing parts and the optional D-BG6 Battery Grip's watertight body prevents the intrusion of water and dust into their interior. When an AW- or WR-series lens is mounted,* the K-1 Mark II and its lens form a remarkable digital imaging system totally resistant to demanding environmental factors.

* AW stands for All Weather (dustproof and weather-resistant construction), while WR stands for Weather Resistant (simplified weather-resistant construction).
