AW: All Weather (dustproof and weather-resistant); WR: Weather Resistant
• To eliminate the potential causes of breakdown or malfunction, we advise you to wipe rain or water off the PENTAX K-70 completely and as soon as possible to keep it dry.
Anticipating many users’ needs for photo shooting in extremely cold locations, the PENTAX K-70 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.
• Battery performance may deteriorate as the temperature of the shooting location goes down. When using the PENTAX K-70 in low-temperature locations, we advise users to carry a spare battery and keep it warm by storing it in a pocket.
The PENTAX K-70 comes equipped with a dependable, high-sensitivity AF sensor module with nine cross-type sensors in the middle. It captures the subject with great accuracy, even in poorly illuminated locations — as low as -3EV — where even the human eye has difficulty in detecting the subject.
The PENTAX K-70’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 can shake it off using high-speed vibrations, preventing any dust spots from appearing on captured images.
Four buttons of the four-way controller are contoured for easy access and unfailing fingertip operation, even with a gloved hand. The mode dial’s height has been optimized for ease of rotation. The PENTAX K-70 has been designed with meticulous attention to every detail to provide optimum comfort and utmost operability.
The PENTAX K-70’s vari-angle LCD monitor allows you to position it at any desired angle, making image composition easier in a variety of Live View outdoor shooting applications, such as high-angle shooting using stretched arms or low-angle shots taken from ground level.
The PENTAX K-70 features a new accelerator unit, which has been designed to optimize the newly developed, high-performance noise-processing technology. In combination with the PRIME MII imaging engine, this unit effectively reduces noise to a 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.
High-performance image sensor unit for fine-detailed images
The PENTAX K-70’s AA-filter-free design eliminates the AA (anti-aliasing) filter, which has an adverse effect on the camera’s resolving power. This 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.
The PENTAX K-70 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 visual effect based on your creative intentions —between the filtering effect of the AA simulator and the higher resolving power of an AA-filter-free design.
* This simulator cannot be used in some shooting modes, and doesn’t work with some functions.
* This simulator works most effectively with a shutter speed of 1/1000 second or slower.
Thanks to the combination of the PRIME MII imaging engine and a newly developed accelerator unit that effectively suppresses noise, the PENTAX K-70 assures true-to-life rendition of gradation and texture at all sensitivity levels.
The PENTAX K-70 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 ultra-wide-angle to super-telephoto models — and minimizes 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. Just 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 18-135mm F3.5-5.6ED AL[IF] DC WR lens, at a focal length of 135mm)
A sharpness-enhancing process using thick outlines often spoils the image’s resolution. That’s why the PENTAX K-70 provides a pair of more advanced sharpness-enhancing functions (Fine Sharpness and Extra Sharpness), which are similar to those offered by upper-class models. 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.
High-quality images assured, even at the edges of the image field
The PENTAX K-70 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 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.
• This function is usable with D FA-, DA- and DA L-series lenses. FA-series lenses are also usable, except for some models.

With an approximately 100% field of view and nearly 0.95-times magnification, the PENTAX K-70’s viewfinder provides a large, sharp view of the subject, allowing you to capture it exactly the way you want. With very little aberration even at the corners of the image field, it assures excellent ease of viewing in many different photographic situations. It also facilitates manual-focus operation, because it makes it easy to locate the in-focus point in the image field.
The PENTAX K-70 features PENTAX’s first Hybrid AF system during Live View autofocus operation. By coupling a contrast-detection AF sensor with superior focusing accuracy with a phase-matching AF sensor positioned on the image sensor’s surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint autofocusing on the subject.
The PENTAX K-70 features the high-precision SAFOX X AF sensor module for viewfinder shooting. Thanks to an AF sensor highly sensitive to low-illumination scenes and a diffractive lens incorporated in its optics, this module assures responsive, dependable autofocus operation with outstanding AF tracking performance in all directions, while minimizing chromatic aberration. By fine-tuning the timing of the AF sensor’s start-up action, the speed of autofocus response has been improved, especially at low illumination levels. Also, by improving the algorithm for moving objects, the focusing accuracy in the Continuous AF (AF-C) mode has been enhanced.
With a top speed of 1/6000 second, the PENTAX K-70’s high-speed shutter unit captures an active subject in a sharply focused image.
The PENTAX K-70’s 11-point AF system has nine cross-type sensors in the middle to allow for flexible image composition. The middle AF sensor accommodates an F2.8 light flux to assure pinpoint focus on the subject, even when using a large-aperture lens with a shallow depth of field. The Select-area Expansion function automatically refocuses on a moving subject after it moves away from the initial point, with the help of the neighboring points.
In addition to the conventional Program (P), Shutter-priority (Tv) and Aperture-priority (Av) modes, the PENTAX K-70 provides the PENTAX-original Sensitivity-priority (Sv) and Shutter-speed/Aperture-priority (TAv) modes. This multi-mode AE system means more creative and flexible expression of the subject’s motion and depth of field. It also provides a wide exposure compensation range of ±5EV (in still-image shooting) with a choice of 1/2EV or 1/3EV steps for more flexible exposure control.
The PENTAX K-70’s metering system divides the image field into 77 segments for high-accuracy light measurement. Thanks to an improved light-metering algorithm, it assures more precise, sensitive exposure control even for high-contrast scenes.
* The PENTAX K-70 also provides a choice of Center-weighted or Spot metering modes.
The PENTAX K-70 provides high-speed 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. Thanks to its large buffer memory capacity, it captures up to 40 JPEG-format images in a single sequence, allowing you to select the best shot later.
* The number of images that can be recorded at ISO 100.
* In the AF Single (AF-S) mode, the AF sensor is fixed at an in-focus point of the first image.

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 color data in each pixel to deliver super-high-resolution images with far more truthful colors and much finer details than those captured by normal shooting processes. The difference in image resolution is evident, even without enlarging the image on the monitor or making a large-size print. When a 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 either 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 the movement is properly corrected with all subjects. The user may turn the Auto Tracking function off in order to optimize the system’s performance.
By mounting the optional O-GPS1 GPS Unit, the PENTAX K-70 provides an automatic tracking function in astronomical photography. The camera calculates the movement of celestial bodies based on GPS data obtained by the unit, then shifts its image sensor in synchronization with their movement. As the result, celestial bodies are captured as beautiful point images without any streaking effects, even with extended exposures.
• In order to properly use the ASTROTRACER function, a number of settings must be input in advance. Refer to the O-GPS1’s operation manual for details.
(F8.0/ 1200 sec./ ISO100)
The bulb timer function comes in handy when photographing celestial bodies or fireworks. The PENTAX K-70 allows you to set an exposure time of 10 seconds to five minutes in 10-second steps, or five to 20 minutes with one-minute steps.
The PENTAX K-70 features a pair of e-dials, which can be used to control the PENTAX-original Hyper operating system. With a turn of either dial, you can instantly shift the aperture or shutter-speed setting without taking your eye from the viewfinder.
In contrast to the auto white-balance control 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.
The PENTAX K-70 provides a selection of 13 Custom Image modes,* so you can apply the preferred finishing touch to your images based on your subject or creative intentions. 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.

You can customize the PENTAX K-70’s operation by assigning the desired functions to the set of buttons, including the Fx1 and Fx2 buttons, and the three USER Mode positions of the Mode dial. It also provides a choice of menu items and the order of their listing displayed on the control panel.
You can assign your favorite camera settings to three User Mode positions of mode dial, then instantly recall the desired settings based on your subject or creative intenstions. The following camera settings, which ae recommended for best results, are initially assigned to the USER Modes as default:
Designed to produce a high-contrast, high-saturation image, this mode emphasizes the clarity and freshness of subjects such as a snowfield in the sun or a crystal-clear lake.
Using the clarity-enhanced Advanced HDR (A-HDR) mode and through adjustment of the Custom Image function, this mode is useful for dramatizing scenic images.
This mode lets you capture beautiful colors of celestial bodies with great ease, while minimizing the fading of black color in the background of astronomical photography. It is also compatible with the ASTROTRACER functions.
The HDR (High Dynamic Range) mode* synthesizes a single, rich-gradation image from three separate images taken at different exposure levels. It delivers an image similar to the one seen by the naked eye, by minimizing whitewashed highlights and pitch-black shadows even in extreme high-contrast scenes. It also lets you set a range of exposure shifts or use the Automatic Position Adjustment function.** You can also choose the Advanced HDR (A-HDR) mode, which creates a dramatic photographic expression by adopting the technologies used in the Clarity control function.
* The HDR mode cannot be used in some shooting modes, and is not compatible with some functions.
** The Automatic Position Adjustment function is fixed at the OFF mode when the Interval or Interval Movie shooting mode is selected. It may not be possible to use this function in all cases, depending on the subject’s status and pattern, and/or the angle of view and focal length of the lens used.
For creating a personalized image with multiple application of special effects
The PENTAX K-70 offers a choice of nine digital filters during shooting, and 21 digital filters during playback. You can apply as many as 20 filters to a single image to create a distinctive, personalized work of photographic art.

Three ways to synthesize creative visual expressions
The PENTAX K-70’s multi-exposure function provides average, additive and comparative brightness settings.
The PENTAX K-70 lets you synthesize a single composite image from two to 2,000 images, while providing three synthesis modes: average, additive and comparative brightness. During Live View shooting, it displays a translucent image of the already captured images on its LCD monitor, allowing you to make precise alignment of the images.
The PENTAX K-70 lets you synthesize a single composite image from images automatically captured at a fixed interval by the Interval Shooting function. Like the multiple exposure function, it provides a choice of three synthesis modes (average, additive and comparative brightness). It even allows you to save already captured images as a separate file midway through a shooting session.
Comparative brightness setting
The PENTAX K-70 has a built-in digital level that detects the horizontal and vertical tilt of the camera with great accuracy, and indicates the obtained information on the LCD monitor. This is a very useful tool in landscape and nightscape photography. It also displays the camera’s horizontal tilt on an exposure bar scale in the viewfinder.
By making effective use of the SR mechanism and digital level, the Auto Horizon Correction 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 turned off, or approx. ±1° with SR mechanism activated
Simply by setting the mode dial to AUTO and pressing the shutter release button, the PENTAX K-70 automatically selects the best shooting mode for a given scene or subject from such options as Portrait, Landscape and Moving Object. This simplifies complicated mode setting operations for first-time SLR users.
The PENTAX K-70 provides 19 distinctive Scene Modes. As soon as you choose one of them, the camera automatically optimizes settings for you.
The multi-pattern auto white-balance control mode sets the proper balance for a given light source. It helps you reproduce colors similar to those seen by the naked eye under confusing lighting conditions, such as when sunny and shady spots coexist in an image field, or when there is a mixing of the camera’s flash illumination and fluorescent lighting in a single scene.
By taking full advantage of lens interchangeability — one of an SLR camera’s greatest strengths — the PENTAX K-70 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 also use the Continuous AF (AF-C) mode* to keep accurate focus on a moving subject, or take advantage of a new aperture control function** to automatically assure the proper exposure level even when faced with fluctuating lighting conditions. 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.

This mode lets you record traces of the stars or illuminations on a 4K-resolution movie file. Using the fade-in and fade-out functions, you can create a fantastic movie.
The PENTAX K-70’s Interval Movie mode allows you to record still images of a slowly changing subject at a fixed interval, link them into a single 4K-resolution (3840 x 2160 pixels) movie file, and play it back,* as if fast-forwarding the time on the screen.
* When playing back the movie file on a device other than the PENTAX K-70, the user is advised to use a PC operating environment supporting 4K-resolution movie playback.
The PENTAX K-70 provides a set of wireless LAN (Wi-Fi) functions* to support operations using mobile devices such as smartphones and tablet computers. Since you can transfer captured images instantly to the mobile device, you can enjoy them away from the camera.
* The dedicated Image Sync application is required to remotely release the camera’s shutter and browse captured images using a mobile device.
By installing the dedicated Image Sync application* in your mobile device, such as a smartphone or tablet computer, you can remotely control camera operations from a distance. For instance, you can adjust camera settings including aperture, shutter speed and ISO sensitivity to the desired level, then release the shutter from your mobile device. You can even download captured images onto the mobile device, then upload your favorite images to social networking service websites.
*Image Sync can be downloaded free of charge from the App Store (for iOS models) or Google Play™ (for Android™ models).
The PENTAX K-70 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.
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.
