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.

AA-filter simulator

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

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.

Accelerator unit

Effective shake reduction with all lenses, assuring improved compensation effects

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.

An array of compensation functions

Diffraction compensation

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

Diffraction blur minimized at closed-down apertures

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.

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.

Automatic detection of difficult lighting conditions

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.

Pixel Shift Resolution System

Normal shooting

Obtained color data

Obtained color data

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

Single-color data is obtained for each pixel.

• High-resolution, rich-gradation images are created from highly resolvable color and brightness data.
• No chromatic moiré (false color) is generated because no pixel interpolation takes place.

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 an interpolated pixel differs from the actual one, chromatic moiré (false color) is generated in that pixel.

Automatic tracking of celestial bodies without an equatorial device

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.
