Rich colors and subtle shades, and a beautiful bokeh and a well-defined sense of depth. When the photographer's inspiration is truly 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 that will fulfill 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 color 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.

6.4MP Full-frame CMOS Image Sensor
The Pentax K-1 Mark II features a 35mm-format full-frame CMOS image sensor with an AA (anti-aliasing) filter–free design to produce high-resolution images with approximately 36.4 effective megapixels. It also features a new accelerator unit, which optimizes the image data obtained by the full-frame image sensor before delivering it to the high-performance PRIME IV imaging engine. Because of this, the camera produces high-quality images with minimal noise, while retaining excellent resolution at all sensitivity levels, from normal to super-high sensitivities. Pentax has also drastically improved the camera’s noise-reduction performance at a high-sensitivity range — up to ISO 819200 — to expand creative possibilities in super-high-sensitivity shooting.

Pixel Shift Resolution System II
features the Pixel Shift Resolution System II, which obtains RGB colour data for each pixel to produce super-high-resolution images with finer details and more truthful colours than those produced by ordinary full-frame sensors. In the new Dynamic Pixel Shift Resolution mode, which can be used during handheld shooting, this system can be used jointly with the camera’s shake-reduction mechanism, since it synthesizes the captured super-high-resolution images by detecting the slight fluctuations of the subject’s position during continuous shooting. The camera also provides ON/OFF switching of the Motion Correction function, which detects moving elements of the continuously captured images to minimize the effect of movement during the image synthesizing process.

High-performance five-axis, five-step SR II system
The Pentax K-1 Mark II comes equipped with the Pentax-developed SR II (Shake Reduction II) five-axis mechanism, which provides accurate control of the large full-frame image sensor with all compatible PENTAX interchangeable lenses. In addition to camera shake caused by pitch and yaw, this advanced system also compensates for camera shake caused by horizontal and vertical shift (often generated in macro photography) and camera shake caused by roll, which is difficult for lens-installed shake reduction mechanisms to handle. It has a compensation range up to five shutter steps (measured in conformity with CIPA standards, using the HD PENTAX-D FA 28-105mm F3.5-5, 6ED DC WR at a 105mm focal length). When taking a panning shot, this system automatically detects the direction of the camera’s movement, and efficiently controls the SR unit to produce the best image possible without requiring any mode switching operation.

Innovative AA filter simulator
By applying microscopic vibrations to the image sensor unit at the sub-pixel level during image exposure, the camera’s anti-aliasing (AA) filter simulator provides the same level of moiré reduction as an optical AA filter. Unlike an optical filter, which always creates the identical result, this innovative simulator not only lets the user switch the AA filter effect on and off, but also adjust the level of the effect. This means that the ideal effect can be set for a particular scene or subject based on given photographic conditions.

Flexible tilt-type LCD monitor
The K-1 Mark II features a flexible tilt-type LCD monitor, which can be tilted to the desired angle horizontally, vertically or diagonally with a single action, without deviating from the lens’s optical axis. The user can not only tilt it approximately 35 degrees horizontally and approximately 44 degrees vertically, but also pull it out from its base to view the on-screen image from above for waist-level photography. This large, 3.2-inch LCD monitor has approximately 1,037,000 dots and a 3:2 aspect ratio, and provides a protective tempered-glass front panel for added durability. In addition to its wide-view design, it also features a unique air-gapless construction, in which the air space between LCD layers is eliminated to effectively reduce the reflection and dispersion of light for improved visibility during outdoor shooting. Its outdoor monitor function, which allows instant adjustment of the monitor’s brightness to the desired level, has also been improved to provide greater visibility in dark locations. Its red-lit monitor display function facilitates monitor viewing when the photographer’s eyes have become accustomed to a dark location during night-time photography.

Easy-to-focus optical viewfinder
Optimized for a 35mm full-frame digital SLR design, the camera’s optical viewfinder provides a nearly 100-percent field of view and an approximately 0.7-times magnification. Thanks to the combination of a condenser lens and aspherical lens, it provides a wide field of view and a clear, undistorted image of the subject. It comes with a Natural Bright Matt III focusing screen, acclaimed for ease of focusing during manual-focus operation, and true-to-life rendition of defocused areas in the viewfinder image. In addition, its transparent viewfinder display makes it possible to superimpose a wide range of photographic data over the viewfinder image.

SAFOX 12 with 33 sensor points and full-frame-proportioned AF frame
Thanks to the SAFOX 12 AF sensor module with 33 AF sensors (25 cross-type sensors positioned in the middle), the Pentax K-1 Mark II optimizes the autofocus process, and assures high-speed autofocus operation in the AF.S (AF Single) mode. The center sensor and two sensors located just above and below it are designed to detect the light flux of an F2.8 lens, making it easy to obtain pinpoint focus on a subject when using a large-aperture lens. Its AF Tracking algorithm has also been revised to improve tracking accuracy of fast-moving subjects in the AF.C (AF Continuous) mode.

Pentax Real-Time Scene Analysis System
By combining an approximately 86,000-pixel RGB metering sensor with the high-performance PRIME IV imaging engine, the Pentax K-1 Mark II’s advanced Pentax Real-Time Scene Analysis System performs real-time analysis of the brightness distribution over the image field and the subject’s colours and movement. Based on this data, it then measures the subject’s lighting conditions with great accuracy and optimizes the exposure. By adopting a breakthrough artificial intelligence technology, deep learning, to its algorithm, it assesses each individual scene more accurately, and optimizes the exposure settings for a given scene or composition.

Compact, solid body with dustproof, weather-resistant construction
The camera’s bottom panel and front and back frames are all made of sturdy yet lightweight magnesium alloy. Although the camera features a dependable, durable shutter unit that can withstand 300,000 shutter releases (measured under actual shooting conditions) for professional use, its body has been downsized to the minimum possible, thanks to the incorporation of a unique floating mirror structure. With the inclusion of 87 sealing parts in the body, the camera also boasts a dustproof, weather-resistant and cold-resistant construction, assuring solid operation at temperatures as low as -10°C.

Full HD movie recording
The Pentax K-1 Mark II captures Full HD movie clips (1920 x 1080 pixels; 60i/30p frame rate) in the H.264 recording format, and comes equipped with a stereo mic terminal for external microphone connection, and a headphone terminal. The user can also adjust the audio recording level manually, monitor sound pressure levels during microphone recording, and cut down wind noise using a new wind-noise reduction mode. In addition to a host of distinctive visual effects for movie recording,* the camera also provides the interval movie mode, which captures a series of 4K-resolution (3840 x 2160 pixels) movie clips at a fixed interval.

Built-in GPS module
Thanks to its built-in GPS module, the Pentax K-1 Mark II provides a variety of advanced GPS functions, including the recording of location, latitude, longitude, altitude and UTC (Universal Time Coordinated) and direction at the time of shooting. The user can easily access images containing GPS data using a computer, to browse them, check on shooting locations and position data on the screen, or save them. The camera also provides a set of other unique tools, including: Electronic Compass, which displays the camera's direction on its LCD monitor; GPS log, which keeps track of the photographer's movement; and ASTRO TRACER, which simplifies the tracing and photographing of celestial bodies by coupling GPS data with the camera's SR mechanism.

The user can easily access images containing GPS data using a computer, to browse them, check on shooting locations and position data on the screen, or save them. The K-1 also provides a set of other unique tools, including: Electronic Compass, which displays the camera's direction on its LCD monitor; GPS log, which keeps track of the photographer's movement; and ASTRO TRACER, which simplifies the tracing and photographing of celestial bodies by coupling GPS data with the camera's SR mechanism.

High-resolution, super-high-sensitivity shooting at ISO 51200 
The K-50 features the state-of-the-art CMOS image sensor with a large image capturing area measuring 23.7mm by 15.7mm, to assure high-speed image data readout. This image sensor is coupled with PRIME M, the same high-performance imaging engine incorporated in upper-class models to deliver super-high-resolution, rich-gradation digital images with approximately 16.28 effective megapixels. The K-50 also offers super-high-sensitivity shooting at a top sensitivity of ISO 51200, allowing the photographer to handhold the camera for beautiful night-time snapshots.

Reliable weather-resistant, dustproof body 
Thanks to the 81 seals set in its compact, lightweight, portable body, the K-50 is built to be weather-resistant, dustproof and cold-resistant, even at temperatures as low as -10°C. This means that the K-50 can be taken along on outdoor activities such as camping, mountaineering and sports, for the joy of high-quality digital SLR photography without worrying about weather conditions. Its compact, functional body is carefully contoured with delicate curves, assuring that even a photographer with a small hand will have a firm grip of the camera.

Innovative SR mechanism 
The PENTAX-developed SR (Shake Reduction) mechanism effectively compensates the adverse effect of camera shake to deliver sharp, blur-free images, even under shake-prone conditions such as when using a telephoto lens, shooting in the dark without flash illumination, or taking landscapes at twilight. This innovative mechanism works with almost all PENTAX interchangeable lenses — even those developed for film-format cameras. Thanks to the SR mechanism’s flexible design, which tilts the image sensor unit in all directions, the K-50 offers several useful features to assist the photographer during shooting, including an Automatic Horizon Correction function to assure high-precision image framing and effortless adjustment of horizontal alignment; a Composition Adjustment function to allow minute adjustment of image alignment both to horizontal and vertical directions, as well as slant-wise rotation; and an ASTRO TRACER mode to simplify astronomical photography in combination with the optional *O-GPS1 GPS Unit (*sold separately).

High-precision autofocus with SAFOX IXi+ AF module 
The K-50 features the state-of-the-art SAFOX IXi+ AF sensor module, which assures responsive, high-precision autofocus operation with 11 sensors (including nine cross-type sensors in the middle). It also features a spot beam projector to assist AF operation at poorly lit locations. Its select-area expansion function keeps the sensor module tracking a moving subject, even when it moves out of a pre-assigned auto-tracking area, by assessing the distance data collected by neighbouring focus sensors. This means not only greatly improved accuracy and speed of detecting moving subjects during autofocus operation, but also the enhanced auto-tracking performance of moving subjects when using a telephoto lens.

High-speed continuous shooting, at approximately six images per second 
When shooting sports, stage performances or wildlife, the K-50’s high-speed continuous shooting function comes in handy. It allows the photographer to record active, fast-moving subjects in a series of images, at a maximum speed of approximately six images per second (in the JPEG recording format).

High-quality movie recording 
The K-50 captures high-resolution, full HD movie clips (1920 x 1080 pixels) in the H.264 recording format, with a choice of frame rate (30, 25 or 24 frames per second). It even comes with creative image-processing tools like Custom Images and useful movie-recording features like an interval movie recording function, for the production of more personalized movies.

Optical finder with approximately 100% field of view 
Despite a compact body common to all entry-class models, the K-50 features a glass prism finder with nearly 100% field of view and approximately 0.92-times magnification (with a 50mm F1.4 lens at infinity) to cover the entire field of view for easy focusing and framing. Since it delivers a clear view of the subject even in bright sunshine and eliminates parallax and time lag in the viewfinder image, the K-50 responds efficiently and reliably to demanding applications and subjects, such as landscapes requiring delicate, high-precision framing, and sports scenes where the timing of shutter release is critical. The in focus point is indicated as a red point in the viewfinder for at-a-glance confirmation.

Effortless, user-friendly Auto Picture and Scene modes 
The PENTAX-original Auto Picture mode automatically selects the most appropriate shooting mode for a given subject or scene from Portrait, Landscape, Macro and other distinctive shooting modes. Since the K-50 sets all vital camera settings — including shutter speed, aperture, white balance, saturation, contrast and sharpness — the photographer can concentrate on image composition and shutter opportunity. The K-50 also offers 19 Scene modes, including Night Scene Portrait, Pet and Backlight Silhouette, to simplify the photographing of subjects and scenes that could be too complicated or demanding for entry digital SLR photographers, by optimizing all camera settings with a simple choice of the corresponding icon on the camera’s LCD monitor.

A selection of image-processing tools for creative, personalized expression 
The K-50’s custom image function allows the user to easily and quickly select the desired finishing touch for a particular image, with a choice of 11 custom images. These include Bleach Bypass to create a dramatic visual effect used in motion pictures, and Cross Process to produce fanciful, eye-catching images with dramatic colours. The K-50 also provides 19 distinctive digital filters to add distinctive visual effects to captured images and produce creative, artistic images without the need for a computer. The user can even explore new creative possibilities by applying multiple filters to a single image.

Choice of two power sources 
In addition to the standard rechargeable lithium-ion battery capable of capturing approximately 480 images with a single recharge, the K-50 can also be powered by four AA-size batteries using the optional *D-BH109 AA Battery Holder (*sold separately). Since AA-size batteries can be easily obtained almost anywhere around the world, there’s no worry about battery shortages, even when on the road.

Newly developed Foveon X3 Quattro direct image sensor 

The SIGMA dp1 Quattro incorporates a newly developed Foveon X3 direct image sensor (generation name: “Quattro”). The new sensor structure features a pixel ratio of 1:1:4 from the bottom, middle to top layer. The Foveon X3 Quattro direct image sensor is able to detect a broad range of light wavelengths. While the top layer captures both brightness and color information, the middle and bottom layers with their larger surface area capture color information only. During the image data processing stage, the brightness data captured in the top layer is applied to the top, middle, and bottom layers, resulting in brightness and color data for each individual pixel. Retaining the principle of the three-layer structure where colors are divided vertically, by applying the brightness data captured in the top layer to the layers below, high resolution and high-speed for broad data processing required are achieved.

Equivalent to 39 megapixel high resolution

A conventional color sensor captures resolution information through green megapixels, which means the information it can contain is only 50% of the whole pixels. On the other hand, the new Quattro sensor captures resolution information with the whole top layer. It holds twice as much resolution compared to conventional color sensors. 19.6 megapixel resolution information of the top layer achieves high resolution equivalent to 39 megapixels.

TRUE III image processing engine

The new dp series cameras feature the newly developed TRUE (Three-layer Responsive Ultimate Engine) III. This image processing engine has evolved in pace with our Foveon direct image sensor and incorporates all of the image processing expertise we have developed over the years. Thanks to new refinements, it is the ideal engine for processing the rich and complex image data produced by the new-generation Foveon X3 Quattro direct image sensor. Our proprietary algorithm makes possible ultrafast processing of an immense volume of image data without any deterioration of the final images. The result is high-definition, 3D-like photographs with outstandingly rich color detail.

High performance 19mm F2.8 lens

Based on our rigorous examination of lens options to match the new Foveon X3 Quattro direct image sensor, we’ve incorporated 19mm F2.8 (equivalent to a 28mm lens on a 35mm SLR) that has a FLD (“F” Low Dispersion) glass, which is equivalent to fluorite in its characteristics, and two glass mold aspherical lenses so as to minimize every type of optical aberration. The superior telecentric optical design improves image quality throughout the frame and maximizes the sensor’s ability by passing on information about subjects to the sensor.
