High-performance viewfinder

Optical viewfinder with approx. 100% field of view, and approx. 1.05X magnification

The PENTAX K-3 Mark III features a high-performance viewfinder with a high-refraction glass pentaprism to provide approximately 1.05-times magnification (with an FA 50mm F1.4 lens set at infinity). Despite the compact, lightweight APS-C-format SLR body, it delivers a truthful, wide-view image equal to that of a full-frame SLR, and helps you to become more fully immersed in the photo-shooting process. This viewfinder also provides an almost 10-percent increase in brightness, thanks to the improved reflectance of the pentaprism, while also assuring a nearly 100-percent field of view. By incorporating a distortion-compensating optical element and optimizing the lens coatings, it provides natural, true-to-life image rendition with high-magnification observations.

Optimizing the sense of immersion in the photo shooting process

Since the viewfinder eyepiece is designed to protrude from the LCD viewfinder display screen — to prevent your nose from contacting the camera body — you can look into the viewfinder more naturally and comfortably. The eyepiece also features an eye sensor, which turns the monitor off the moment you bring your eye up to the eyepiece ring. This prevents the status screen’s illumination from affecting visibility during shooting, while allowing you to capture images more comfortably.


Optimizing the ease of operation

The PENTAX K-3 Mark III features a transparent LCD viewfinder display that provides a broader range of data in the viewfinder window. Because you can adjust the camera’s settings without taking your eye away from the viewfinder, you can concentrate more fully on the subject. The camera also allows you to program the desired combination of display data, such as grid pattern and AF focus point, making it easier to swiftly change settings for a specific scene or subject.

Operability that affects sensibility

Pleasant shutter action

The PENTAX K-3 Mark III features a leaf switch, a mechanism previously used in the PENTAX 645Z and PENTAX K-1. Compared to the tactile switch more commonly used in compact SLR cameras, the leaf switch provides a lighter, smoother shutter action and minimizes the camera shake caused by the shutter-release action. It also helps you by providing effortless hold-down of the shutter-release button during continuous shooting. The time lag between the shutter release and an image capture has also been reduced, compared to the PENTAX K-3 II, while the camera’s mirror- and shutter-driving mechanisms have also been upgraded. By reducing unwanted mechanical actions such as mirror bounce, it provides crisp, pleasant shutter-release action. You can feel the smooth action and speedy response every time you press the shutter-release button.

Ergonomic design for responsive camera operation

For comfortable shooting and easy carrying, the PENTAX K-3 Mark III’s grip and control-button layout have been optimized to accommodate different hand sizes and finger lengths. Perfected after producing a series of mock-ups and conducting repeated verifications, they let you to concentrate completely on your photo shooting.

New-generation Hyper Operation system

The conventional Hyper Operation system allows you to instantly shift the AE mode to Tv (Shutter-priority) or Av (Aperture-priority) when the camera’s exposure mode is set to P (Program). The PENTAX K-3 Mark III's new-generation Hyper Operation system provides more flexible exposure-mode control, by adding a new Advanced mode* to the conventional Standard mode.

*The Standard mode is set as default. The Advanced mode is a customizable option.


By turning the front/rear electronic dial, you can instantly switch the AE mode from P to Tv or Av. Also, by providing single-action switching between Tv and Av, this mode assures intuitive operation in capturing an image, by emphasizing the subject’s motion, or the depth of field of the scene.


This new mode not only provides speedy switching between Tv and Av, but also features instant shift to the TAv (Shutter/Aperture-priority) mode simply by changing the shutter-speed and aperture settings. Also, by changing the ISO sensitivity setting, you can flawlessly shift to the M (Manual) mode, harmonizing the easy photo-shooting of Programmed AE operation with the flexible exposure control of manual operation.

More versatile Smart Function

The PENTAX-original Smart Function provides easy, single-action selection of menu items and functions. Featuring a new Smart Function button, the PENTAX K-3 Mark III now lets you preprogram a maximum of five functions from 22 options, and displays a list of the selected functions in the viewfinder window, so you can select the desired function without removing your eye from the viewfinder. It even lets you select and program the desired values for each function, allowing you to more precisely customize this function to meet your preferences.

Treasure your lenses as a valuable asset

Compatibility with classic lenses

You must be aware that each of your classic and cherished lenses creates its own distinctive ambience in captured images. That’s why the PENTAX K-3 Mark III has been designed to accommodate classic lenses. The camera not only saves the aperture value as Exif data when you set a desired aperture using the electronic dial, but also lets you measure the light and capture images at closed-down aperture. It even accommodates the TAv mode.* It also provides more segmented setting of the lens’s focal length in SR (Shake Reduction) shooting.

*The PENTAX K-3 Mark III allows AE photography at the closed-down aperture for M-series lenses and lenses that previously could be used only in open-aperture shooting.

Manual input of lens focal length

When required to manually input the focal length of a lens for SR operation, the PENTAX K-3 Mark III allows you to select a desired length from the history log, in addition to the preprogrammed ones, to minimize the time and trouble required for manual setting.

The imaging power to capture images delicately, boldly or dramatically

Complete renewal of key devices

New back-illuminated CMOS imaging sensor with approximately 25.7 megapixels

To further improve image quality, the PENTAX K-3 Mark III incorporates a newly adopted, back-illuminated imaging sensor with approximately 25.7 effective megapixels. It also features an AA (anti-aliasing)-filter-free design to faithfully reproduce the delicacy of light, or the fine outlines of a subject.

CMOS Image sensor

PRIME V imaging engine and second-generation accelerator unit

For the PENTAX K-3 Mark III, PENTAX developed the PRIME V imaging engine and the second-generation accelerator unit. This combination provides a harmony of flawless, high-speed operations and super-high-sensitivity, high-quality imaging, all at a level of performance higher than ever before. The overall performance of the PENTAX Real-time Scene Analysis System and the autofocus system has also been much improved to ensure: flawless, high-speed operation; super-high-sensitivity, high-resolution imaging; better autofocus performance; and a broader range of shooting functions.

Accelerator unit

Superb imaging power over the entire sensitivity range

Thanks to its multi-dimensional image space filtering process, the PENTAX K-3 Mark III greatly reduces noise, while still retaining the subtle outlines of a subject. This advanced technology optimizes the camera’s resolving power, and faithfully reproduces the subject's texture and detail. It also improves image description in the lower sensitivity range, while minimizing unfaithful reproduction of blacks in the higher sensitivity range where color reproduction becomes more difficult. Even at the top sensitivity of ISO 1,600,000, it delivers a natural, well-defined image with a sharp subject outline and vivid colors.

New-generation Fine Sharpness function

Thanks to the incorporation of the new PRIME V imaging engine, the PENTAX K-3 Mark III features the much-improved Fine Sharpness function to more faithfully and finely reproduce the subject's outline and detail. Preset as a default setting, this function reproduces the subject's details more naturally and sharply, while reducing the adverse effect of noise to a minimum.

The never-ending pursuit of high-quality imaging

With the renewal of the image sensor, imaging engine and accelerator, PENTAX has further enhanced the PENTAK K-3 Mark III’s image quality. This was based on PENTAX's image design concept emphasizing the faithful reproduction of detail and texture. Through repeated sensibility evaluations, PENTAX made great improvement in overall image quality, by efficiently controlling the camera’s noise-reduction process while paying the utmost attention to the total balance of captured images, with an emphasis on factors such as the natural reproduction of gradation and color.

PENTAX Real-time Scene Analysis System

This PENTAX-original system, which performs an in-depth analysis of each individual scene by assessing such factors as the brightness distribution over the image field and the subject’s shape, color and motion, has been greatly upgraded, thanks to the incorporation of a new RGBIr AE sensor with approximately 307,000 pixels, which detects the subject in greater detail than before. Coupled with the state-of-the-art imaging engine, it performs accurate detection of the subject's face and eyes in viewfinder shooting, along with high-precision tracking of moving subjects. Combined with an image recognition system adopting Deep Learning technology, it provides highly dependable exposure control and automatic selection of the optimal focus point.

RGBIr AE sensor

For faithful reproduction of impression colors engraved in your memory

Custom Image

To apply the finishing touch that recreates the impression or emotion you felt during shooting, the PENTAX K-3 Mark III's Custom Image function features 13 distinctive modes to add a variety of visual expressions.* Each mode offers effortless adjustment of parameters such as saturation, tone, key, contrast and sharpness.**

* When the mode dial is set to AUTO, this function is locked to the Auto Select mode.

**Selectable parameters vary depending on a selected Custom Image mode.

Custom Image parameter setting menu

(Color Temperature Enhancement)

This unique white balance mode allows you to emphasize an impression color and dramatize your personal impressions for such scenes as dramatic sunrises and sunsets, fresh green leaves in spring, or clear, blue skies in summer. In contrast to the standard Auto White Balance mode, it adjusts the white balance setting to emphasize the image's dominant color to create a distinctive visual effect.

SR (Shake Reduction) mechanism

SRII for five-axis, 5.5-shutter-step camera shake compensation

The PENTAX K-3 Mark III's SR II mechanism compensates for camera shake caused by horizontal and vertical shift, roll, pitch and yaw, with a wide compensation range up to approximately 5.5 shutter steps.* In addition to the all-purpose Auto mode, this mechanism also provides a Panning mode to capture slow-moving subjects. You can choose the mode that provides the ideal compensation effect for your subject.

*In terms of the shutter speed used for still images: measured in conformity to CIPA standards, using an HD PENTAX-DA 16-85mmF3.5-5.6ED DC WR lens set at a focal length of 85mm.

Pixel Shift Resolution System

By taking advantage of the SR II mechanism, this innovative system* captures four images of the same scene by slightly shifting the image sensor for each image to obtain all RGB color data for each pixel, then synthesizes them into a single, super-high-resolution composite image. This assists the camera in producing super-high-resolution images with true-to-life colors free of false color or noises — something conventional cameras fail to deliver.

*When using this system, the user is advised to stabilize the camera firmly on a tripod during shooting.

5) Each pixel obtains color and brightness information of every RGB

AA (anti-aliasing) filter simulator

This PENTAX-original simulator* effectively minimizes moiré and false color by activating the SR II mechanism to apply microscopic vibrations to the image sensor during exposure. For ordinary shooting, you can turn this off to maximize the camera's resolving power as delivered by its AA-filter-free design. Then you can activate it for certain scenes or subjects which require a filtering effect.

*This function works most effectively with a shutter speed of 1/1000 second or slower.
*This function cannot be used in some shooting modes, or when combined with certain functions.

Capture a split second of light

High-speed drive system

High-speed drive, with a maximum speed of approximately 12 images per second

Thanks to the combination of a newly developed mirror and shutter driving unit and the high-speed, high-performance PRIME V imaging engine, the PENTAX K-3 Mark III provides a high-speed drive system with a maximum speed of approximately 12 images per second in the AF.S mode, or approximately 11 images per second in the AF.C mode. This system lets you capture a momentary expression of the subject, which couldn’t otherwise have been captured by previous models.


*The continuous shooting speed may decrease depending on the type of lens used and/or the aperture, shutter speed and sensitivity selected by the user.

*A certain amount of time is required for the playback of images captured in the continuous shooting mode. The time required may vary depending on the number of captured images and/or the recording format.

High-speed, high-precision mirror and shutter driving unit

To improve driving speed during continuous shooting and upgrade the performance of AF and AE systems, the PENTAX K-3 Mark III features a new mirror and shutter driving unit to greatly reduce the time needed to drive the mirror and shutter mechanisms. By minimizing the effect of mirror bounce, it also helps increase the camera’s driving speed, while securing sufficient time for distance and light measurements. As the result, the operation time required to capture a single image has been reduced to about two-thirds of the PENTAX K-3 II.

Approach 1:

Highly dependable, responsive coreless motors are installed to drive the mirror and shutter mechanisms. Light sensors monitor the position of the cam gears driven by these motors with great precision, assuring more accurate control of the drive and stop points of these mechanisms during high-speed continuous shooting.

Approach 2:

The weight of the entire main mirror unit has been reduced to minimize collision energy, while a new damper mechanism instantly stops the mirror action to reduce mirror bounce. The sub-mirror’s drive and stop mechanism also features a new design to optimize mirror action and reduce mirror bounce.

SAFOX 13 AF system with 101 focus points

The number of focus points in the PENTAX K-3 Mark III have been increased to 101, from 27 in the PENTAX K-3 II. The AF area also has been greatly expanded. Of 41 user-selectable points,* 25 are cross-type sensors. This high-density AF system enhances the flexibility of image composition, while optimizing focusing accuracy on the subject. Since its middle focus point is designed to detect an F2.8 luminance flux, the camera assures super-high-precision focusing when using a bright lens with an open aperture of F2.8 or larger. *The number of selectable points may vary depending on the mounted lens.

AF area selection

The PENTAX K-3 Mark III provides a choice of the AF area from Auto Area, Zone Select, Select, Expanded Select Area (S, M or L), Select (S) and Spot. A newly installed AF point selector lever makes it easier to intuitively select the optimum focus point. Since the camera displays the selected AF coverage area and the selected AF focus point in the viewfinder window, you can adjust the image composition and select the focus point simultaneously.

High-precision AF operation at -4EV illumination

Since the camera’s F2.8-sensitive light sensor operates even at -4EV illumination, it assures remarkable imaging power for dimly lit subjects when using a lens with an F2.8 luminance flux.

Outstanding image tracking performance

The camera features a new, high-capacity RGBIr image sensor with approximately 307,000 pixels, to provide more accurate tracking of subjects in motion or slight movement than previous models. It assures outstanding image tracking performance by correlating and assessing the data delivered by the tightly positioned AF focus points.

High-precision continuous shooting in AF.C mode

The camera’s continuous autofocus (AF.C) mode allows you to maintain sharp focus on a subject, regardless of direction of motion. An improved motion prediction algorism accurately detects the subject’s complex movement, which was rather difficult to predict with previous models. It also reduces the effect of the unstable motion speed and irregular stops and restarts, as well as the effect of obstacles.

SR II’s Panning mode

The camera’s in-body SR II mechanism provides an independent Panning mode. Thanks to the SR II's improved operation, you can move the camera in a slow panning motion to capture distant, slow-moving subjects, whose motion was difficult to detect with conventional cameras. Since the camera allows you to switch the SR II’s mode between OFF and AUTO with a single push of the SR button, you can react quickly and effortlessly to a change of scene or subject.

Always keep the PENTAX K-3 Mark III handy, whenever you want to capture an image

Compact body

In developing the PENTAX K-3 Mark III, PENTAX focused especially on superb handling and easy carrying — the most prominent features associated with APS-C-format SLR cameras. While making many functional improvements over the PENTAX K-3 II, PENTAX kept the width and height at the same dimensions as the PENTAX K-3 II, while reducing the depth (the space between the lens mount and the LCD monitor surface) by approximately 2.5mm. This slim design allows for a greater protrusion of the viewfinder eyepiece to make image-viewing easier, while realizing PENTAX’s design concept of a compact body size and easy viewfinder photography.

Dustproof, weather-resistant construction

Both the camera body and the optional D-BG8 Battery Grip are designed to be dustproof and weather-resistant to prevent the intrusion of dust and water. When an AW- or WR-series lens is mounted,* they form a highly airtight imaging system that assures dependable performance even in adverse weather conditions.

*AW stands for All Weather; WR stands for Weather Resistant.

Excellent cold-resistant performance down to -10°C

Anticipating use in low-temperature locations, PENTAX has subjected the camera to exacting environmental tests at temperatures as low as -10°C*, while assessing the performance of its mechanisms and electronical circuits and measuring the precision of optical components.

*Battery performance declines as the temperature goes down. When shooting in low-temperature environments, the user is advised to carry spare batteries and keep them warm by storing them in an inside pocket.

All-surface magnesium-alloy body

The PENTAX K-3 Mark III’s top, bottom, front and rear panels are all made of magnesium alloy. This lightweight, high-rigidity material not only protects the camera’s internal mechanisms from shock and vibration, but also creates the look of a solid, high-grade camera body.

Highly durable shutter unit

Installed in the camera body, the extra-durable shutter unit withstands a total of 300,000 shutter release actions at a speed of 12 images per second,* contributing to an improvement in continuous shooting speed and an increase in the number of recordable images.

*Measured under RICOH in-house testing standards.

Dual SD-card slot

The PENTAX K-3 Mark III provides a pair of SD card slots. One of the slot conform to the UHS-II standard for high-speed data writing operation. You can save data files on two separate memory cards, with a choice of recording modes: Sequential, Duplicate and RAW/JPEG Separation. You can also copy images for transfer between the two cards.

DR II (Dust Removal II) mechanism

By applying ultrasonic vibrations generated by a piezoelectric element to the optical glass plate in front of the image sensor, this mechanism effectively removes dust particles from the image sensor surface, and prevents annoying dust spots from appearing on captured images.

Outdoor-friendly monitor with the Night Vision Display function

The camera features an outdoor-friendly LCD monitor whose brightness level can be easily adjusted to the desired level: make it brighter during outdoor shooting in sunshine, or dimmer during nighttime photography. This monitor also provides a Night Vision Display function, which minimizes eye strain or fatigue after the photographer’s eyes have become accustomed to a dark location during nighttime shooting, such as astronomical photography.
