State-of-the-art imaging processing system
Greatly improved image quality, even in high-sensitivity photography NEW
Accelerator Unit
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.

PRIME IV
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.
35mm full-frame image sensor
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.
Approximately 36.4 effective megapixels
AA-filter-free design to optimize 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.
AA filter simulator
State-of-the-art mechanism to optically minimize moiré and false color
The PENTAX-original AA (anti-aliasing) filter simulator* effectively minimizes moiré and false color by using the camera's SR mechanism to apply microscopic vibrations to the image sensor during exposure. It provides the option of choosing the AA-filter effect for well-balanced images or the AA-filter-free mode for greater resolving power.
- * This function works most effectively with a shutter speed of 1/1000 second or slower.
- * This function may not be used in some shooting modes, or may not be combined with certain functions.
