35mm full-frame CMOS image sensor

Exceptional imaging power assured by a large-format sensor

The Pentax K-1 incorporates a newly developed 35mm full-frame CMOS image sensor, one that assures the highest image quality to be found in the K-mount SLR series. Thanks to its large imaging area and wide pixel pitch, this high-pixel sensor delivers lively, true-to-life images with rich gradation and minimal noise. Its shallow depth of field allows you to control the sense of depth and bokeh (defocused) effect at will.

Approximately 36.4 effective megapixels

Exceptional resolving power supported by a high-resolution, AA-filter-free design

Thanks to its approximately 36.4 effective megapixels, the Pentax K-1 delivers breathtaking, true-to-life images—the kind that will seize the viewer’s imagination. Its exceptional resolving power captures each leaf of a distant tree or every drop of a spray in the finest detail. Since it provides image data large enough to produce a brilliant A2-size print (at 300dpi), the photographer is assured of great flexibility in image composition, either by cropping the image during shooting, or trimming the captured image during processing. By processing large volumes of data with its 14-bit image-processing system, the Pentax K-1 delivers beautiful, rich-gradation images.

AA-filter-free design, to optimize resolving power

An optical AA (anti-aliasing) filter will affect the camera’s image resolving power, even though it will help reduce moiré and false color. The Pentax K-1 incorporates an AA-filter-free design to optimize the image resolving power of its high-pixel image sensor.


A new imaging engine optimized for a 35mm full-frame image circle

The Pentax K-1 features a newly designed PRIME IV imaging engine. Compared with the previous PRIME III version, it is fine-tuned to process higher-resolution images, while boosting the operating frequency by nearly 50 percent. Its noise-processing algorithm has also been upgraded to capture beautiful, fine-gradation images at higher sensitivities. A combination of an advanced scene analysis system and new image-processing functions helps improve the accuracy and reliability of image reproduction.

ISO 204800

A combination of super-high sensitivity and exceptional image resolution

By taking full advantage of the image sensor excelled in noise-resistance performance and the PRIME IV imaging engine, the Pentax K-1 provides a top sensitivity of ISO 204800 (at standard output sensitivity). This not only delivers high-resolution images free of tone jumps and graininess at high-sensitivity settings, but also improves image quality in the low-sensitivity range. Since the Pentax K-1 allows you to raise the sensitivity level to capture images equal in image quality to those taken at lower sensitivities, it expands the boundaries of photographic expression.

Pixel Shift Resolution System

Reproduction of true-to-life, super-high-resolution images beyond actual pixels

Reinforced with the SR (Shake Reduction) mechanism, the Pentax K-1’s Pixel Shift Resolution System* captures four images of the same scene by shifting the image sensor by a single pixel for each image, then synthesizes them into a single, super-high-resolution composite image. Compared to the conventional Bayer system, this innovative system obtains all RGB color data in each pixel to deliver beautiful images with far more truthful colors and much finer details, without any hint of false color. This system also reduces high-sensitivity noise to a minimum. The difference in image quality is evident at a glance, even without magnifying the captured image on a computer screen or producing a large-size print. Images captured by the Pixel Shift Resolution System can be saved as RAW-format files. You can developed these files within the camera body while adjusting various parameters or turning the Pixel Shift Resolution effect on and off to create a new image.

When using this system, the user is advised to stabilize the camera firmly on a tripod during shooting by setting the drive mode to self-timer or remote control, or using the mirror lock-up function.

When the subject is on the move or camera shake occurs, the desired effect may not be obtained.

Motion Correction function

When shooting an image with the Pixel Shift Resolution System, the Pentax K-1 provides a new Motion Correction function. When this function is activated, the camera automatically detects the amount of subject motion during continuous shooting and minimizes negative effects during the synthesizing process.*

The movement may not be sufficiently corrected when the subject is moving in certain directions and/or patterns. This function does not guarantee that the movement will be properly corrected for all subjects.

AA filter simulator

State-of-the-art mechanism to optically minimize moiré and false color

By using the camera’s SR mechanism to apply microscopic vibrations to the image sensor, the PENTAX-original AA (anti-aliasing) filter simulator* effectively minimizes moiré and false color along the image’s edges, which are common problems when shooting subjects with minute patterns. The Pentax K-1 allows you to faithfully reproduce your creative intention on a captured image, either by simulating the AA-filter effect for well-balanced images or by opting for 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 combined with some shooting modes.

Lens Aberration Correction and Fringe Compensation

High-quality image reproduction a the image field, with effective compensation of aberrations

The Pentax K-1 effectively compensates for the distortion, vignetting and chromatic aberration caused by specific lens properties, and captures high-quality images with edge-to-edge sharpness. It even compensates for the fringe effect during RAW-data development.

Available in combination with D FA-, DA-, DA L- and FA-series lenses. However, some of these lenses may not be compatible with these functions.

Fine Sharpness and Extra Sharpnes

Sharpness-enhancing tools to greatly improve the image rendition of high-pixel photography

No matter how many pixels and how much resolving power an image sensor may provide, the captured image can appear as a low-resolution image if the subject is outlined with thick lines. The Pentax K-1’s 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. It allows you to create a fine piece of art, with a true-to-life description of the subject. The Pentax K-1 also provides an Extra Sharpness function, which emphasizes the subject’s outline more prominently with much finer lines, making it particularly useful for enhancing the outline of a low-contrast subject.

SR II in-body shake reduction mechanism

The world’s first 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.

For a 35mm full-frame digital SLR camera, as of February 2016 (based on RICOH IMAGING research).

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 Pentax K-1 captures beautiful, high-resolution images both in normal shooting and panning photography, without requiring any switching operation.

Operation Assist Light

Supporting camera operations in the dark

Four Operation Assist Lights are strategically positioned around the camera body: at the upper side of the lens mount, behind the LCD monitor, at the memory card slot, and at the cable switch terminal. With a push of the illumination button, you can turn them on* to facilitate lens and memory card changes, control button operations, and attachment and removal of a cable switch, for more efficient, comfortable shooting of nighttime outdoor scenes and poorly lit indoor subjects.

The LED lights can be switched on and off individually. They are all set to the off mode at default setting.

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 Pentax K-1 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 Pentax K-1 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.

Outdoor-oriented LCD monitor

Single-action setting of LCD monitor’s brightness

With a single push of a button, the Pentax K-1’s new Outdoor View Setting mode displays five brightness settings on its LCD monitor, allowing you to easily and quickly set the desired brightness level for a given location — brightening the monitor under dazzling sunshine or darkening it under starlit skies.

Dependable dustproof, weather-resistant construction

A completely environment-resistant imaging system, with a weather-resistant lens

A combination of the Pentax K-1’s 87 sealing parts and the optional D-BG6 Battery Grip’s watertight body prevents the intrusion of water and dust into their interior. When an AW- or WR-series lens is mounted,* the Pentax K-1 and its lens forms a remarkable digital imaging system totally resistant to demanding environmental factors.

AW stands for All Weather (dustproof and weather-resistant construction), while WR stands for Weather Resistant (simplified weather-resistant construction).

–10°C cold-resistant construction

Unmatched reliability proven under vigorous testing conditions

Anticipating use in cold locations, PENTAX has subjected the Pentax K-1 to exacting environmental tests at temperatures as low as –10°C, and gathered a vast array of data on operational precision, response and stability of mechanisms and circuits, as well as fluctuations in battery voltage.* As the result, the Pentax K-1 assures solid, trouble-free operation even at freezing temperatures.

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

DR II (Dust Removal II) mechanism

Effective removal of foreign particles from the image sensor

Using its piezoelectric element, this innovative mechanism applies ultrasonic vibrations to the optical glass panel placed in front of the image sensor. This effectively removes all dust particles clinging to the image sensor surface, and prevents annoying dust spots from appearing on a captured image.

High-rigidity, extra-durable body

A shell structure shielding a metallic chassis with a magnesium alloy casing

The Pentax K-1’s exterior casing is made of highly rigid, lightweight magnesium alloy, which provides excellent shock-resistance and electromagnetic shielding performance. By coupling it with a high-rigidity metallic chassis housing the core components, the Pentax K-1 forms a compound structure to assure outstanding durability and exceptional reliability.

Extra-durable shutter unit

Withstanding 300,000 shutter releases for professional use

After a series of exacting performance tests, the Pentax K-1’s shutter unit has proven its exceptional durability by withstanding a total of 300,000 shutter releases. It assures outstanding operational precision and exceptional durability required for exacting professional work.

Flexible Tilt-Type LCD monitor

Innovative mechanism to tilt the monitor to any desired angle along the optical axis

Aiming at aligning the photographer’s line of sight precisely with the camera’s optical axis while providing a flexible angle adjustment, PENTAX has designed an ideal LCD monitor for the Pentax K-1 by creating an innovative mechanism that supports the monitor with four stays. This monitor has reached two difficult goals that conventional monitors have failed to attain: no deviation from the optical axis; and unrestricted tilt in all directions, horizontally or vertically. You can even tilt it up to a nearly 90-degree angle for low-angle and waist-level photography.

・Vertical tilt: approx. 44°

・Horizontal tilt: approx. 35°

(Waist-level shooting: approx. 90°)

Air Gapless LCD monitor

Air Gapless LCD monitor The Pentax K-1’s Air Gapless LCD monitor uses a special resin layer applied between the protective panel and the LCD screen to effectively cut down internal reflections. Coupled with the Outdoor View Setting function, it assures excellent visibility even under bright sunshine.

Live View shooting

A choice of grid display from five patterns and two colors (white or black)

Zoom display with a maximum magnification of 16 times for easy confirmation of focus status

Auto Horizon Correction and Composition Adjustment

Convenient tools to compose well-balanced images

By taking advantage of its SR mechanism, the Pentax K-1 helps you compose well-balanced, flawless images. The Auto Horizon Correction function* rotates the image sensor to compensate for the camera’s horizontal tilt, making it useful in handheld shooting. The Composition Adjustment function** allows you to make minute adjustment of image composition with a shift of the image sensor. It comes in handy for Live View shooting using a tripod.

Maximum compensation angle: approx. ±2° (approx. ±1° with SR mechanism activated)

Maximum compensation range: ±1.5mm (±1mm along the axis of rotation) or ±1°

Digital level

Accurate detection of camera tilt without removing the eye from the subject

The Pentax K-1’s Digital Level displays bar scales at the right side and bottom of the viewfinder to indicate the horizontal and vertical tilt of the camera, allowing you to confirm the horizontal and vertical alignment of the subject without taking the eye off the subject. You can also display the Digital Level on the LCD monitor during viewfinder shooting, Live View shooting and movie recording

Smart Function

Single-action function control

The Pentax K-1’s Smart Function is a brand-new camera operation system harmonizing an array of features with ease of operation. This functional camera operation system lets you swiftly choose and set the desired function using just two dials positioned on the camera’s upper panel, without needing to refer to the menu screen on the LCD monitor.

Built-in GPS module and Electronic Compass

Automatic recording of shooting position data

The Pentax K-1 features a built-in GPS module and Electronic Compass, which together display the camera's direction on the LCD monitor. These features allow you to attach Exif data to recorded images, including the location, direction and time of shooting (using Universal Time Coordinated). This comes in particularly handy in situations where you must make meticulous preparations in advance for the direction of shooting, such as the shooting of sunrise scenes and celestial bodies.

GPS Log to track the photographer’s movement

The Pentax K-1’s GPS Log function automatically keeps track of the photographer's movement at fixed intervals. By loading a log file on your computer, you can trace the route you have traveled using a mapping application such as Google Earth™.


Effortless tracking and photographing of celestial bodies without an equatorial telescope

By making full use of its GPS module, Electronic Compass and SR mechanism, the Pentax K-1 simplifies the astronomical photography of celestial bodies, without the help for an equatorial telescope. Based on the latitude data obtained from GPS satellites and other affecting factors (the camera’s direction and horizontal/vertical tilt) obtained by its various sensors, the Pentax K-1 calculates the movement of celestial bodies, then synchronizes the movement of its image sensor with that of celestial bodies with great precision. Since it captures stars without a streaking effect even during extended exposures, you can record faint stars, which are difficult to detect with the naked eye, as point images.

The user is advised to use a tripod to stabilize the camera.

The user is advised to read the operating manual thoroughly before shooting.

ASTROTRACER cannot be used with some shooting modes, such as interval shooting and interval composite shooting.

Optical viewfinder with a nearly 100% field of view

Assuring a clear view of the field and ease of focus

The Pentax K-1’s optical viewfinder provides a nearly 100-percent field of view and a 0.7-times magnification to deliver a sharp, crisp view of the subject and a large, well-defined image field, both of which are the benefits of the 35mm full-frame SLR camera. This viewfinder also provides a clear view of the image field free of aberrations, even at the edges. Its Natural-Bright-Matte III focusing screen* makes it easy to identify the in-focus point, even during manual-focus operation

The focusing screen is fixed on the camera body, and is not interchangeable.

Transparent viewfinder display

At-a-glance confirmation of the camera’s operational status

The Pentax K-1’s transparent LCD viewfinder display allows you to select desired data, such as a grid display, and monitor it in the viewfinder. It comes in handy when correcting the camera’s tilt using the digital level or rearranging the image composition using a grid pattern, without taking the eye off the subject.

Digital Level

The Digital Level displays the Pentax K-1’s horizontal and vertical tilt with two bar scales. Compared with the conventional type that utilizes an exposure bar scale, it not only makes it easier to identify the camera’s tilt, but also allows you to check the tilt and exposure status simultaneously. As the result, it greatly improves the camera’s operability during viewfinder shooting

Selection of data on viewfinder display

Transparent data to be displayed in the viewfinder (grid pattern, Digital Level, AF frame and spot-metering frame) can be turned on and off independently to accommodate varying shooting conditions and preferred shooting styles.

All APS-C-format, K-mount interchangeable lenses are usable on the Pentax K-1

From ultra-wide angle to super telephoto, an entire selection of high-performance DA-series lenses can be used on the Pentax K-1 without any modification. They deliver exceptional image quality, despite their compact, lightweight design.

Crop mode

Automatic switching of an image area with attachment of a lens

When a DA★-, DA Limited- or DA-series lens is mounted on the Pentax K-1, its Crop mode automatically switches an image area to the APS-C size covering the middle section of the image field, while displaying the cropping frame in the viewfinder. It not only assures high-resolution images with approximately 15.36 effective megapixels, but also provides an efficient AF sensor coverage of the image area for more flexible image composition during autofocus operation. When you select the FF (Full Frame) setting of the Crop mode, you can even capture a 35mm full-frame image with a DA-series lens.*

With certain lenses and/or under certain photographic conditions, a captured image may suffer a drastic drop in brightness and/or resolution in the areas outside the APS-C image area. This setting does not provide compensation of various lens aberrations.

Compact, solid body

Remarkable maneuverability, despite the 35mm full-frame design

The Pentax K-1 inherits PENTAX’s development concept of a compact body and ease of handling in the field. PENTAX has completely restructured the mechanical unit containing the shutter charge and mirror driving mechanisms, while repositioning the finder unit to keep the camera’s height to a minimum. PENTAX’s advanced high-density packaging technology has succeeded in creating a compact, maneuverable body for the new Pentax K-1.

Floating Mirror Structure

In order to accommodate the 35mm full-frame image sensor and cover the light flux of the large viewfinder with a nearly 100-percent field of view, it was necessary to increase the size of the main mirror and mirror box. To minimize the size of the mirror box, PENTAX has developed a new mechanism that retracts the main mirror as it swings upwards.

PENTAX Real-time Scene Analysis System

Optimizing the performance of AE and AF systems and the ease of image composition

Supported by the approximately 86,000-pixel RGB light-metering sensor and the new PRIME IV imaging engine, the PENTAX Real-time Scene Analysis System analyzes such factors as brightness distribution in the image field, the subject’s primary color and its motion with great accuracy and efficiency. In addition, by adopting a breakthrough artificial intelligence technology called deep learning to its image detection algorithm*, this system assesses each individual scene more accurately, while optimizing the accuracy and performance of the light-metering, exposure-control and autofocus systems, and selecting the most appropriate finishing touch for a given scene or composition.

This RICOH-original technology is available during viewfinder shooting when the exposure mode is set to Scene Analyze Auto and the Custom Image mode is set to Auto Select.


Newly developed AF system, with an expanded AF detection area

The Pentax K-1’s AF frame has been widened to optimize the ease of image composition over a larger 35mm full-frame image field. Thanks to the development of a new SAFOX 12 AF sensor module, its autofocus area is approximately 40 percent wider than a conventional AF frame.* In order to contain a longer optical path required for the expanded AF area within a compact housing, the Pentax K-1 features an innovative, efficient optical design in which the incoming light is turned back within the AF module. Thanks to the optimization of the condenser lens, it also provides an increased number of AF sensor points (33 in total). This state-of-the-art AF module boosts both compact dimensions and exceptional image-forming performance.

SAFOX 12 AF module

This new AF sensor module features two reflex mirrors. By reflecting the incoming light flux twice on these mirrors, it provides a longer optical path, while its overall size has been kept nearly identical to that of SAFOX 11

86,000-pixel RGB light-metering sensor

High-precision scene analysis based on the subject’s color, shape and motion

The Pentax K-1’s approximately 86,000-pixel RGB light-metering sensor not only delivers outstanding resolving power, but also detects colors with great precision. After accurately measuring the subject’s shape, primary color and motion, it feeds the obtained data to the PENTAX Real-time Scene Analysis System for extra-accurate scene analysis.

33-point AF system with 25 cross-shaped sensors

Zone Select

This mode lets you select a set of nine points forming a square, which can be shifted as desired by moving the center point. It detects a subject placed within this square, optimizes the focus, and tracks its movement — all automatically.

Select-area expansion

This mode lets you select one of 33 AF points to focus on the subject, and makes the Pentax K-1 automatically track the subject and refocus on it with the help of the neighboring points, even when it moves away from the initial point. You can select the desired expansion area from nine, 25 or 33 points.*

The number of AF points may decrease if the selected expansion area includes an area or areas outside the AF frame.

Auto tracking with PENTAX Real-time Scene Analysis System

Supported by the PENTAX Real-time Scene Analysis System, the Pentax K-1’s Auto Tracking function accurately detects the subject’s motion based on various factors including color, then keeps pinpoint focus on the subject throughout the imaging process by automatically shifting the in-focus point.

Scene Analyze AUTO

Much-improved accuracy, through the adoption of artificial intelligence technology

Supported by the PENTAX Real-time Scene Analysis System, the Pentax K-1’s Scene Analyze AUTO mode automatically optimizes exposure settings, and selects the most appropriate finishing touch for your subject. When using the optical viewfinder, it is also assisted by an algorithm that adopts the deep learning artificial intelligence technology, and makes an extensive analysis of a given scene based on the enormous volume of data accumulated from previous scenes.

Multi-mode AE system

A choice of distinctive auto-exposure modes

In addition to the conventional Program (P), Aperture-Priority (A) and Shutter-Priority (Tv) modes, the Pentax K-1 also provides the PENTAX-original Sensitivity-Priority (Sv) and Shutter-speed/Aperture-Priority (TAv) modes, both of which assure proper exposure on the subject by factoring the ISO sensitivity more prominently into exposure-control operation. This multi-mode system assures more flexible control of exposure settings to express the subject’s motion or the depth of field. It also provides a wide exposure compensation range of ±5EV (in still-image shooting) to expand a range of exposure control.

1/8000-second high-speed shutter

Exceptional operational accuracy and remarkable durability

The Pentax K-1 features an electronically controlled, vertical-run shutter to optimize the performance of the 35mm full-frame image sensor. With a top speed of 1/8000 second, it allows you to open up the aperture, even in bright locations, and take full advantage of the bokeh (defocus) effect created by the large image sensor. It also provides a flash synchronization speed of 1/200 second. Symbolizing the Pentax K-1’s field camera concept, this unit is designed to be compact and lightweight, with a well-balanced combination of high-precision operation and outstanding durability.

High-speed drive mode

Flawless continuous shooting at approximately 4.4 images per second
