The K-1 takes greatness to the next level. As the first full frame DSLR engineered under the PENTAX brand, the K-1 brings outstanding performance, operability and affordability to photographers. With its large 36.4 megapixel CMOS image sensor, the K-1 incorporates all of the performance of a high-resolution full frame 35mm digital camera as well as all of the unique PENTAX-original features and technologies that photographers have become accustomed to, in a compact, rugged, weather-resistant body.

High-resolution, fine-gradation images supported by approximately 36.4 effective megapixels
The K-1 features an AA filterless design that prioritizes image resolution. Coupled with the new PRIME IV imaging engine, capable of 14-bit
RAW-format image recording. The K-1's unique full frame sensor and imaging engine design also allows for super-high-sensitivity shooting up to ISO 204800, producing beautiful, high-resolution images

In-body SR mechanism assures optimal shake reduction performance
The SR II five-axis mechanism enables 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, it effectively compensates for camera shake caused by horizontal and vertical shift, as well as camera shake caused by roll, which is difficult to deal with by lens-installed shake reduction mechanisms. Even when taking a panning shot, this system automatically detects the direction of the camera's movement, and efficiently controls the SR unit to always produce the best image possible.

Pixel Shift Resolution System with a new motion correction function
The K-1 uses the latest super-resolution technology, which captures four images of the same scene by shifting the image sensor by a
single pixel for each image, and then synthesizes them into a single composite image. Since the K-1's SR unit has a flexible design that tilts the image sensor unit in all directions, it provides a host of handy shooting functions, including auto level compensation, image-composition fine-adjustment, and ASTRO TRACER, which simplifies advanced astronomical photography using a built-in GPS module.

Flexible tilt-type LCD monitor to accommodate various shooting angles
The K-1 features a newly designed, flexible tilt-type LCD monitor, which tilts horizontally, vertically or diagonally with a single action,
without deviating from the lens's optical axis. 35 degrees of horizontal and 44 degrees of vertical adjustment can be achieved, the LCD panel can even be laid flat up or down. The 3.2-inch LCD monitor features a tempered-glass front panel for added durability and a unique air-gapless construction effectively reduces reflection.

Newly developed SAFOX 12 with 33 sensor points and full-frame-proportioned AF frame
The SAFOX 12 AF sensor module features 33 AF sensors (25 cross-type sensors positioned in the middle). The center sensor and the 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.

Upgraded PENTAX Real-Time Scene Analysis System, with application of artificial intelligence technology
The K-1's advanced PENTAX Real-Time Scene Analysis System performs near instant analysis of exposure, color, movement and other
factors. Combining with a breakthrough artificial intelligence technology called deep learning, the K-1 instantly optimizes settings for even the most difficult shooting situations.

Easy-to-focus optical viewfinder with nearly 100-percent field of view
Newly developed for its 35mm full-frame design, the K-1's optical viewfinder provides a nearly 100-percent field of view and an
approximately 0.7-times magnification. A Natural Bright Matt III focusing screen allows ease of focusing and a true-to-life rendition of defocused areas in the viewfinder image.

Operation Assist LED Lighting
The GPS feature records shooting location, facing direction, and date and time into image data. Electronic Compass records the shooting
direction, and Astro Tracer combines these features with SRII shake reduction to capture rock-steady images of heavenly objects in the night sky without streaking or blurring during long exposures.
