Ricoh Imaging announces the new Pentax K-1 Mark II


The PENTAX K-1 Mark II, the new flagship of the acclaimed 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 new 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.

The K-1 Mark II incorporates Pixel Shift Resolution System II. This new, PENTAX-developed 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. In addition, the new Dynamic Pixel Shift Resolution mode allows photographers to produce crisp, ultra-high pixel shift resolution images without the need of a tripod.

High-performance five-axis, five-step SR II system

The PENTAX-developed in-body SR II (Shake Reduction) five-axis mechanism provides accurate control of the large full-frame image sensor with all compatible PENTAX interchangeable lenses* at a compensation range of up to 5 shutter steps. 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 control with 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.

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 throughout the frame). 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 large-aperture F2.8 lenses

Easy-to-focus optical viewfinder with nearly 100-percent field of view

The K-1 Mark II’s optical viewfinder provides a nearly 100-percent field of view and an approximately 0.7-times magnification. A Natural Bright Matte III focusing screen allows ease of focusing and a true-to-life rendition of defocused areas in the viewfinder image.

High-speed continuous shooting

The PENTAX K-1 Mark II allows continuous recording of as many as 17 images in the RAW format (or a maximum of 70 images in the JPEG Best format) in a single sequence, at a top speed of approximately 4.4 images per second. This is made possible by the combination of advanced mechanisms including a damper mechanism that effectively minimizes mirror shock; high-speed, high-precision control of the shutter and mirror units; and a high-speed data transmission system incorporated in the PRIME IV imaging engine.

 Supportive shooting functions to improve picture-taking efficiency and operational comfort

Operation assist light function provides LED lights above the lens mount, behind the LCD monitor, at the memory card slot, and at the cable switch terminal to help facilitate fast and easy operation in poorly lit settings. The key lock function prevents erroneous operation of the four-way controller and other exposure-related control buttons. The Smart Function allows users to swiftly choose and set desired functions using just the function dial and the set dial on the camera’s upper panel, without referring to the menu screen on the LCD monitor.

Compact, solid body with dust proof, weather-resistant construction

Constructed of sturdy yet lightweight magnesium alloy with the inclusion of 87 sealing parts in the body, the K-1Mark II also boasts a dust proof, weather-resistant and cold-resistant construction.
