The Pentax K-1 Mark II, the new flagship of the Pentax K-series lineup, delivers outstanding image quality and improved operability in a broad-range of shooting conditions. It features a full-frame Anti-aliasing (AA)-filterless CMOS sensor with 36.4 effective megapixel resolution. An accelerator unit that -along with the camera's PRIME IV image processor- enables it to produce high-resolution images with minimal noise in even in the most challenging low-light conditions, up to ISO 819200.

36.4MP - Full-Frame CMOS Sensor

The full-frame size CMOS sensor supported by approximately 36.4MP 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 for a creating you high-resolution images with a wide-range of bokeh expression. 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.

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.

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

The K-1 Mark II incorporates Pixel Shift Resolution System II. This upgraded technology uses the same in-camera shake-reduction (SR) mechanism and sensor-shift capabilities as the original Pixel Shift Resolution System, capturing four images of the same scene, and then synthesizes them into a single, super-high-resolution composite image. With the Pixel Shift Resolution System II, the camera also obtains RGB color data, resulting in images with significantly finer details and truer colors than those produced by typical full-frame sensors.

Dynamic Pixel Shift Resolution

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 a tripod. From the technology point of view, when you are using a tripod, the Pixel Shift Resolution II images will produce higher resolution.

Built-in Shake Reduction Mechanism, SR II

Just like the Pentax K-1 the K-1 Mark II is equipped with a 5-Axis, SR II system. To achieve this technology an acceleration sensor is used. The 5-axis SR II covers the shake of yaw, pitch, roll, vertical, and horizontal. Additionally, the shake reduction performance system offers 5 shutter steps compensation. With the SR II mechanism, camera shake can be prevented even with high-resolution images. As always, as the SR II is built-in, SR II is effective with every K-mount lenses.
