AA-filter-free design APS-C-size CMOS image sensor with 24.24 effective megapixels

High-performance image sensor unit for fine-detailed images

The PENTAX KF’s AA-filter-free design optimizes the resolving power of the approximately 24.24 effective megapixels provided by the high-resolution APS-C-size CMOS image sensor, while assuring high-speed readout of rich-gradation, 14-bit image data.

Top sensitivity of ISO 102400

Super-high-sensitivity photography and remarkable imaging power

The PENTAX KF features an accelerator unit, which has been designed to optimize the high-performance noise-processing technology. In combination with the PRIME MII image engine, this unit effectively reduces noise to minimum, even during super-high sensitivity shooting at ISO 102400 (standard output sensitivity). This combination not only improves image quality at more commonly used sensitivities, but also delivers beautifully depicted images at higher sensitivities by minimizing graininess. As the result, it expands the boundaries of low-illumination photography.

ISO 12800

In-body SR mechanism

Effective shake reduction with all lenses, assuring optimum compensation effects

The PENTAX KF features the PENTAX-original, in-body SR (Shake Reduction) mechanism with a compensation effect of 4.5 shutter steps.* It works effectively with all PENTAX interchangeable lenses – from wide-angle to telephoto models – and minimize camera shake in camera-shake-prone conditions, such as when shooting low-light scenes using natural light only or when using a telephoto lens. It also comes in handy with panning shots, since it automatically detects the direction of the camera’s movement with a gyro sensor, and efficiently controls the SR unit to produce the best possible image. Simply by keeping the SR mode turned on, you can effortlessly minimize camera shake with both normal images and panning shots.

* Measured in conformity with CIPA testing standards (using the smc PENTAX-DA 18-135mmF3.5-5.6ED AL [IF] DC WR lens, at a focal length of 135mm)

Pixel Shift Resolution System

Optimizing the potential of the high-pixel image sensor to capture super-high-resolution images

By taking advantage of the SR (Shake Reduction) mechanism, this innovative system* captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizing them into a single composite image. It obtains all RGB color data in each pixel to deliver super-high-resolution images with a far more truthful colors and much finer details than those captured by normal shooting processes. When the Motion Correction function** is activated, it automatically detects a moving object during continuous shooting and minimizes negative effects during the synthesizing process. The images captured by this system can be saved as RAW-format files.

* When using this system, we advise stabilizing the camera firmly on a tripod. The user is also advised to use the self-timer setting of the drive mode, a remote-control function, or a mirror lock-up function.
* This system may not produce the desired effect when the subject is on the move or the camera is shaken.
** This system may not correct certain types of subject movement. It does not guarantee that movement is properly corrected for all subjects. The function can be turned off when desired.

Pixel Shift Resolution

Obtained color data

The camera takes four images of the scene, and obtain the RGB color data and brightness data for each pixel.

R:24M

G:24M×2

B:24M

High-resolution, rich -gradation images are created from highly resolvable color and brightness data.

No chromatic moiré (false color) is generated because of no pixel interpolation takes place.

 

Normal shooting

Obtained color data

Single-color data is obtained for each pixel.

R:6M

G:6M×2

B:6M

Based on the RGB composition ratio, the resolution of each color becomes 1/4 for R and B, and 1/2 for G.

De-mosaic process

The system interpolates for missing pixels by referring to neighboring pixels and/or outlines.

 

When the color of the interpolated pixel differs from the actual one, chromatic moiré (false color) is generated in the pixels.

AA-filter simulator

State-of-the-art function to minimize moiré and false colors

The PENTAX KF features an AA (anti-aliasing) filter simulator,* which effectively minimizes the moiré patterns often generated on subjects with fine, repetitive patterns, and the false colors commonly generated at the edges of high-contrast images. With the help of the SR (Shake Reduction) mechanism, this simulator applies microscopic vibrations to the image sensor unit at the sub-pixel level during image exposure to minimize these adverse effects. It lets you choose the desired balance between the filtering effect of the AA simulator and the higher resolving power of an AA-filter-free design, based on your creative intentions.

* This simulator may not work with some shooting modes, or with certain functions.
* This simulator works most effectively with a shutter speed of 1/1000 second or slower.

White balance control

In addition to AUTO WB, which is designed to reproduce white without any color shift under all light sources, the PENTAX KF provides 13 more preset White Balance modes, including Multi Auto WB and CTE.

White Balance Modes

AUTO WB, Multi Auto WB, Daylight, Shade, Cloudy, Fluorescent Light (Daylight Color), Fluorescent Light (Daylight White), Fluorescent Light (Cool White), Fluorescent Light (Warm White), Tungsten Light, CTE (Color Temperature Enhancement), Manual WB, Color Temperature Configuration, Copying the white balance setting of a capture image

CTE Color Temperature Enhancement

For faithful reproduction of the colors of your memory

In contrast to the AUTO WB (AWB) mode, which works to minimize the influence of light sources on color reproduction, the CTE mode automatically sets the white balance to optimize their influence, allowing you to express such subjects as sunrise and sunset scenes and fresh green leaves in dramatic tones close to memory colors.

Special-edition Custom Image modes

The special-edition Custom Image modes are highly unique, creative imaging tools that allows you to capture attractive images with distinctive themes. Each special-edition mode is partnered with particular lenses for optimum visual effects.

Special-edition Custom Image modes

The PENTAX KF provides 19 distinctive Scene Modes. As soon as you choose one of them, the camera will automatically optimize the settings for you.

Scene Modes:
Portrait, Landscape, Macro, Moving Object, Night Scene Portrait, Sunset, Blue Sky, Forest, Night Scene, Night Scene HDR, Night Snap, Food, Pet, Kids, Surf & Snow, Backlight Silhouette, Candlelight, Stage Lighting, Museum

Fine Sharpness and Extra Sharpness

Sharpness-enhancing tools to improve the image rendition of photographic works

A sharpness-enhancing process using thick outlines often spoils the image’s resolution. That’s why PENTAX KF provides a pair of more advanced sharpness-enhancing functions. The Fine Sharpness function outlines the subject with thinner, more natural lines than those created by normal processing to produce a high-quality, fine-detailed image. The Extra Sharpness function emphasizes the subject’s outline more prominently with much finer lines, making it particularly useful for enhancing the outline of a low-contrast subject.

Clarity control and Skin Tone correction

For effortless control of the subject’s texture

The Clarity control function is an image-processing tool useful in expressing the luster of metal or the clarity of the sky or water. It allows you to adjust the smoothness of the subject’s surface and express desired texture or clearness at nine levels (between -4 and +4 settings). The Skin Tone correction function* helps you reproduce the subject’s face with soft skin texture and healthy skin tone, while retaining a high-resolution description of the subject’s hair and outfit and the background. It provides a choice of two modes: Type 1 for the compensation of color and brightness only, and Type 2 for additional control of skin tone.

* The Skin Tone correction function makes compensation only when the camera detects a face in the image.

An array of lens compensation functions

High-quality images assured, even at the edge of the image field

The PENTAX KF effectively compensates distortion, vignetting and lateral chromatic aberration of magnification caused by particular characteristics of a lens to deliver sharp, high-contrast images, even at the edges. During RAW-data development, it can even compensate the fringe effect.

Diffraction compensation

Diffraction blur minimized at closed-down apertures

This function compensates the deterioration in the camera’s resolving power that is caused by diffraction phenomena. By properly using lens information to process image data, it compensates the diffraction blur effect by as much as approximately two aperture stops.* This function comes in handy in scenic photography, when you want to close the aperture down to increase the depth of field without compromising the resolving power.

* Measured under RICOH IMAGING in-house testing standards.
* Compatible with D FA-, DA-, DA L-, and FA-series lenses. (Some FA-series lenses are incompatible with this function.)

1/6000-seconds high-speed shutter

To capture the decisive moment with an active subject

With a top speed of 1/6000 second, the PENTAX KF’s high-speed shutter unit captures an active subject in a sharply focused image. Faster shutter speeds are also effective in bright scenes, allowing you to open up the aperture to throw the background out of focus.

Continuous drive mode with a top speed of six images per second

Continuous shooting up to 40 images at approximately six images per second

The PENTAX KF provides continuous shooting of high-resolution images (approximately 24.24 effective megapixels, 14-bit data files) at a top speed of approximately six images per second, allowing you to preserve the action or expression of the subject in a series of images up to 40 JPEG-format images* in single sequence.

* The number of images that can be recorded at ISO 100.

Outstanding cold-proof performance down to -10°C

Excellent reliability proven in stringent operation tests

Anticipating user demands for photo shooting in extremely cold locations, the PENTAX KF was subjected to stringent environmental tests in temperatures as low as -10°C. Its dependable cold-weather performance assures stable, responsive, high-precision operation of mechanisms and circuitry, while minimizing fluctuations in battery voltage, even in freezing locations.* Its dustproof, weather-resistant body works superbly and dependably, even in snowy locations.

* Battery performance may deteriorate as the temperature of the shooting location goes down. When using the PENTAX KF in low-temperature locations, we advise users to carry a spare battery and keep it warm by storing it in a pocket.

Outdoor-friendly LCD monitor with a red-lighted monitor display function

Easy adjustment of brightness to a desired level

The PENTAX KF features an outdoor-friendly LCD monitor whose brightness level can be instantly adjusted to the desired level: brighter during outdoor shooting in sunshine, or dimmer during nightscape photography. It also provides a red-lighted monitor display function, which prevents the pupils of the photographer’s eyes from closing down after they have become accustomed to a dark location during astronomical photography. This monitor is designed to assure optimum visibility in a wide range of photographic conditions and applications.

Auto Horizon Correction

A convenient tool for easy composition of well-balanced images

By making effective use of the SR mechanism and the digital level, the Auto Horizon function automatically rotates the image sensor to compensate for the camera’s horizontal tilt.* This is especially useful when photographing poorly illuminated subjects, or shooting in an unstable, off-balance position.

* Maximum compensation angle: approx. ±1.5°with SR mechanism turn off, or approx. ±1° with SR mechanism activated

DR (Dust Removal) mechanism   

Easy removal of dust particles from the image sensor

The PENTA KF’s image sensor is treated with PENTAX-original SP coating to prevent dust from clinging to the surface. If any dust remains on the surface, the PENTAX-original DR (Dust Removal) mechanism shakes it off using high-speed vibrations, and prevents dust spots from appearing on captured images.

In-body RAW data development

Application of the desired finishing touch without a computer

The PENTAX KF allows for in-body development of RAW-format files, with the developed files saved as separate JPEG files. You can adjust a wide range of parameters, and add the desired finishing touch to your image without needing a PC. You can even develop RAW-format files created by the Pixel Shift Resolution System or those recorded in the HDR mode.

Movie recording

Many creative ways to enjoy movie recording

By taking full advantages of lens interchangeability – one of an SLR camera’s greatest strengths – the PENTAX KF captures high-resolution Full HD movie clips. Because you can set the desired aperture, you can flexibly use creative shooting techniques, such as blurring the background with a shallow depth of field, or creating a work of art similar to a theatrical film by capturing a movie at a rate of 24 frames per second, the same frame rate as filming. During movie recording, you can use the Continuous AF (AF-C ) mode. It even provides a host of user-friendly tools, such as a digital SR (Shake Reduction) mechanism, digital filters and stereo sound recording using a built-in microphone.

The lens compatible with the AF-C mode are:

Digital Camera Utility 5

Standard software for high-quality finishes

Included as a standard accessory, Digital Camera Utility 5 software allows you to browse through captured images on a computer screen, and develop RAW-format files to save them as JPEG- or TIFF- format files. Because you can change colors and check photographic data on the computer screen, you can take your time in finishing the image exactly the way you want it.
