AA-filter-free design to optimise 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 minimise moiré and false colour

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.

The advanced Pixel Shift Resolution System II for super-high-resolution images

A PENTAX technology to produce high-quality images beyond the power of total pixels

PENTAX's Pixel Shift Resolution System II* is the super-solution technology which realizes image resolving power and color reproduction far better than that of the conventional Bayer system. By taking advantage of the camera's SR mechanism, it captures four images of the same scene by slightly shifting the image sensor for each image, obtaining all RGB color data and luminance data from each pixel, then synthesizing them into a single, super-high-resolution composite image. It not only improves image resolving power, but also prevents the generation of false color, reduces high-sensitivity noise, and greatly improves image quality.
* When using this system, the user is advised to stabilize the camera firmly on a tripod during shooting, and set the drive mode to self-timer or remote control, or use the mirror lock-up function.
** The desired effect may not be obtained when the subject is on the move or camera shake occurs.

RAW-format filing compatibility

The images captured by the Pixel Shift Resolution System can be saved as RAW-format files. You can develop these files within the camera body while adjusting various parameters or turning the Pixel Shift Resolution effect on and off to create the desired image.

Innovative Dynamic Pixel Shift Resolution mode

Greater flexibility in handheld shooting

In addition to conventional shooting modes, the Pixel Shift Resolution System II features a new Dynamic Pixel Shift Resolution mode*, an innovative technology that takes advantage of slight fluctuations of the subject's position during handheld shooting. The camera closely analyzes four captured images and detects camera shake during handheld shooting before synthesizing them into a super-high-resolution composite image.** By combining this mode with the camera's SR mechanism, you can use the advanced Pixel Shift Resolution System II more flexibility, even in difficult shooting conditions such as shooting at poorly lit locations or without using a tripod.
* When using a tripod, the user is advised not to activate the Dynamic Pixel Shift Resolution mode.
** Captured images may not be properly synthesized with certain subjects or under certain conditions. By capturing images in the RAW or RAW+ format, the user can process the images unsuitable for the synthesizing process as normal RAW-format images within the camera body.

SR II in-body shake reduction mechanism 

Five-axis, five-shutter-step camera shake compensation

The PENTAX-original sensor-shift-type shake reduction mechanism has been upgraded to provide optimum compensation for all lenses used in handheld shooting. The new-generation SR II (Shake Reduction II) features a five-axis mechanism to compensate for camera shake caused by horizontal and vertical shift* (often generated in macro photography) and camera shake caused by roll, which is difficult to handle by lens-installed shake reduction mechanisms, in addition to more common camera shake caused by pitch and yaw.

The SR II unit is controlled with great precision as soon as the camera's power is turned on, and provides a wide compensation range - as much as five shutter steps** - to expand the limits of handheld shooting.
* During Live View shooting, this mechanism does not compensate for camera shake caused by horizontally and vertical shift.
**Measured in conformity to CIPA standards, using an HD PENTAX-D FA 28-105mm F3.5-5.6ED DC WR lens at a focal length of 105mm.

Compatible with panning shots

When taking a panning shot, this mechanism efficiently controls the SR unit to detect only the direction of the camera’s movement, while compensating for all other affecting vectors. Because of this, the K-1 Mark II captures beautiful, high-resolution images both in normal shooting and panning photography, without requiring any switching operation.

High-precision AE/AF operation at -3EV illumination

Extra-accurate auto-exposure and autofocus control, even in the dark

An illumination level of -3EV makes it difficult to see a subject with the naked eye, and almost impossible to make accurate focus with manual focusing. Even under such low-illumination conditions, the K-1 Mark II assures high-precision auto-exposure and autofocus operations.*
Thanks to its upgraded algorithm, its autofocus response time for poorly illuminated subjects is greatly reduced. Coupled with its super-high-resolution imaging power, the K-1 Mark II delivers exceptional shooting performance in dark locations.
* Light metering measured at ISO 100 and with a 50mm F1.4 lens; focusing measured at ISO 100, at room temperature and with 25 middle sensors.

The K-1 Mark II's Custom Image function allows you to apply the preferred finishing touch to your image, based on your subject or creative intentions. With the addition of Auto Select, in which the camera automatically detects the type of scene or subject and selects the best finishing touch for you, and Flat, which produces a base image most tolerant to retouching, the K-1 Mark II provides a total of 13 Custom Image modes.* Each mode provides minute adjustment of parameters such as saturation, shade, key, contrast and sharpness.**
* The Custom Image mode is fixed to Auto Select when the camera's exposure mode is set to AUTO.
** Adjustable parameters may vary depending on the selected Custom Image mode.

Clarity control and Skin Tone correction

Compensation of the subject's texture, while retaining the image's overall sharpness

The Clarity control function is an image-processing technology effective in reproducing the glossy texture of metals and the clearness of the sky or splashing water. By adjusting the smoothness of a silky or shiny surface, it lets you control the quality of texture and the degree of clarity.

The Skin Tone correction function** restores a tender texture and a healthy tone of the subject's skin, while keeping the high-resolution rendition in its hair and clothing and in the background. It depicts your subject with smooth texture and healthy skin tones.
* Both of these functions are technologies developed by RICOH Co., Ltd.
** The Skin Tone correction function can be activated only when the Face Detection mode is selected.

HDR

Faithful reproduction of highlights and shadows

The K-1 Mark II's HDR (High Dynamic Range) mode* delivers an image similar to that detected by the naked eye, by minimizing white-washed highlights and pitch-black shadows, even with extreme high-contrast scenes.
It also allows you to set a range of exposure shifts or use the Automatic Position Adjustment function.** Since this mode can save original image files in the RAW format, you can develop them by changing HDR settings or turning the HDR mode off.
By using a PC and the included software, you can also divide a single RAW-format file into three separate RAW-format images, and save them as independent files.
* This HDR function cannot be used in some shooting modes, and is not compatible with some other functions.
** The Automatic Position Adjustment function is fixed at the OFF mode when the Interval or Interval Movie shooting mode is selected.

Multiple exposure

Three ways to synthesize highly creative images

The K-1 Mark II lets you capture the desired number of images - from two to 2,000 - to synthesize a single composite image, with three synthesis modes: average, additive and comparative brightness. In Live View shooting, the K-1 Mark II displays a translucent image of the already captured image on its LCD monitor, allowing you to make precise alignment of the images.

CTE

For expressing the colors of the mind, rather than truthful color reproduction

In contrast to the standard auto white balance mode, which is designed to suppress the effect of a light source color on the image's color reproduction, the CTE (Color Temperature Enhancement) mode emphasizes the image's dominant color based on the color temperature. It is useful in dramatizing sunrise and sunset scenes or snow-covered landscapes under the cloudy sky. It is also effective in preventing color fading or the loss of colors such as dark greens and faint pinks.

Digital filters

A selection of filters to add creative visual effects

The PENTAX K-1 Mark II provides a choice of nine filters during shooting, and 21 filters during playback, to create unique visual effects on your images. You can apply as many as 20 filters to a single image to create a distinctive, personalized work of art.

Movie recording

Full HD movies with a beautiful bokeh effect

The K-1 records lively, true-to-life movies. Thanks to a shallow depth of field provided by its 35mm full-frame design, it effectively produces a beautiful bokeh effect. You can also record sound in stereo using a stereo microphone (commercial product, not included with the K-1), or monitor it during recording using headphones (commercial product, not included with the K-1).

4K-compatible Interval Movie Shooting

Documenting a constantly changing subject in high resolution

The K-1’s Interval Movie mode allows you to record still images of a slowly changing subject at a fixed interval, and link them into a single movie file. You can play back the 4K-resolution (3840 x 2160 pixels) movie file,* as if fast-forwarding the time on the screen. The K-1 also provides the Star Stream function, which lets you draw the magical traces of stars in a movie.
* When playing back the movie file on a device other than the K-1, the user is advised to use a PC operating environment supporting 4K-resolution movie playback.

Dual card slot

Large-volume image data filing on two SD memory cards

The K-1’s card slot accepts two SD memory cards, with a choice of three data filing modes: “Serial” to store a large volume of data successively from one card to another; “Duplicate” (simultaneous filing) for simplified data backup, and “RAW/JPEG Division” to separate data files based on the recording format.
It is also possible to copy an image stored on one card to another.

In-body RAW data development

Application of the desired finishing touch without a computer

The K-1 provides in-body development of RAW-format files, with the developed files saved as separate JPEG or TIFF files. This offers greater flexibility in finishing a captured image more faithfully to your creative intention, without the help of a PC. Thanks to a wide range of adjustable parameters, you can add a desired finishing touch to your image regardless of a location, until you are truly satisfied with the result. The K-1 also features a newly designed user interface for more effortless, more flexible parameter control.

IMAGE Transmitter 2 compatibility

Tethered photography from a personal computer

By installed the optional IMAGE Transmitter 2 tethering software on your PC and connecting it with the K-1 via USB terminal, you can operate the K-1, automatically transfer and save recorded images, and check photographic data on your computer. This greatly improves the efficiency of studio shooting. Note: For proper use, the software must be upgraded to the latest version. Please access our official website for details.
