Take greatness to the next level with the first compact, full frame DSLR engineered by PENTAX for outstanding performance, operability and affordability.


High ISO Sensitivity

ISO 819,200 (Still)
ISO 25,600 (Video)

As the combination of PRIME IV and the RICOH developed Accelerator Unit drastically reduces noise, allowing for high sensitivity up to ISO 819,200.

By exceeding the upper limit of sensitivity, the range of practical sensitivity will be widened with beautiful images with the wider selection of shutter speed and aperture combination. This can be easily done using the TAv mode. The ISO for video has also been increased to ISO 25,600.

36.4 Effective Mega Pixel – Full-Frame CMOS Sensor

The Full-Frame size CMOS sensor (35.9mm x 24.0mm) supported by approx. 36.4 Megapixels delivers high resolution while suppressing noise levels. The larger sized CMOS sensor which is 1.5x larger than that of APS-C also produces a shallower depth of field. With the increase in resolution and the larger size of the Full-Frame sensor, users can enjoy very high resolution images with a wide range of bokeh expression. The larger Full-Frame sensor also increases the individual pixel pitch ( individual pixel size) from 3.91µ with APS-C sized sensors to 4.88µ. This increase allows the sensor to collect more light, resulting in improved S/N ratio (signal to noise ratio) resulting in improved noise performance. The K-1 Mark II’s sensor is also AA (anti-aliasing) filter-less to fully utilize the image quality of the sensor.

PRIME IV with RICOH Developed Accelerator Unit

The PRIME IV with 14-bit imaging processing engine coupled with our original Accelerator Unit, (a RICOH developed processing device) effectively suppresses noise and reproduces fine-details with rich colors even at high ISO levels. The Accelerator Unit was first introduced in the PENTAX K-70, followed by the KP and is now being introduced in the K-1 Mark II, marking the 3rd generation. We have been able to achieve the highest results from this newly designed Accelerator Unit based on our increased knowledge and experience.

Pixel Shift Resolution II

Pentax Pixel Shift Resolution has been very well accepted with the PENTAX K-3 II, K-70, and KP. We have adopted an upgraded version of the Pixel Shift Resolution to PENTAX K-1 Mark II. The system is apart from the conventional Bayer system, which only captures single unit of color data in each pixel. Pixel Shift Resolution captures four images of the same scene by shifting the image sensor by a single pixel, using the SRII mechanism. With this, each pixel captures all colors, resulting in super-high-resolution images, true to life colors with much finer details, while significantly lowering the level of high-sensitivity noise.

Motion Correction is also featured in K-1 Mark II. Therefore, when the PRIME IV processor detects moving objects, that section of the image will not be composed and will only use one of the four taken images for that portion. The Pixel Shift Resolution of the PENTAX K-1 Mark II, has been upgraded to Pixel Shift Resolution II as we have added a new Dynamic Pixel Shift Resolution.

Dynamic Pixel Shift Resolution

Since we introduce Pixel Shift Resolution, we have received many request to use without the use of a tripod. With the K-1 Mark II, we are able to achieve this request by featuring Dynamic Pixel Shift Resolution. To select Dynamic Pixel Shift Resolution, select -> Pixel Shift Resolution -> Image Stabilization On, which appears as one of the modes in the Pixel Shift Resolution menu.

This technology is a revolutionary technology which comes from reverse thinking to utilize the minute camera shake itself to produce the composite images. Therefore, by detecting the camera shake in three dimensions, the continuously captured four images are analyzed based on the detected camera shake information and produce one super high resolution image.

During the Dynamic Pixel Shift Resolution, as the image is not captured using sensor movement like traditional Pixel Shift Resolution, the SR II system can be used to correct for camera shake. By coupling both features, Dynamic Pixel Shift Resolution can be effectively used during low light situations even without tripod. From the technology point of view, when you are using tripod, the Pixel Shift Resolution II images will produce higher resolution.
