High-performance AF system to capture sharp, crisp images in a wide range of photographic scenes
smc PENTAX-DA★ 60-250ｍmF4ED[IF] SDM Aperture:F4.0 ; Shutter speed: 1/250 sec. ; Exposure compensation: 0.0EV ; ISO sensitivity:400 ; White balance: Multi-pattern auto white-balance ; Custom image: Bright
Optical viewfinder with 100% field of view and 0.95-times magnification
For optimum ease of viewing and focusing
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.
High-speed AF operation during Live View shooting
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 an image-plane 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.
Vari-angle LCD monitor
For flexible outdoor shooting
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.
High-speed, high-precision AF module highly responsive to low-illumination scenes and moving objects
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.
1/6000-second high-speed shutter
To capture the decisive moment with an active subject
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.
11-point multi-pattern AF system
Delay-free detection of the subject
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 Expanded Area Select function automatically refocuses on a moving subject after it moves away from the initial point, with the help of the neighboring points.

- Linear sensor
- F2.8 luminance flux linear sensor
Multi-mode AE system
A diverse choice of AE modes
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.
Advanced 77-segment multi-pattern metering
Automatic detection of difficult lighting conditions
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.
High-speed, continuous drive mode with a top speed of six images per second
Flawless continuous shooting of up to 40 images at approximately six images per second
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.
