Super-high-resolution images captured with 24.24 effective megapixels and a top sensitivity of ISO 102400
The K-70 features a state-of-the-art 24.24 effective megapixel AA Filter-less APS-C sized CMOS sensor for outstanding image quality. By coupling a newly developed accelerator unit with the high-speed PRIME MII imaging engine, the K-70 effectively minimizes noise at all sensitivity levels, and captures richly gradated, finely detailed images even in super-high-sensitivity shooting at a top sensitivity of ISO 102400.
Hybrid AF system for high-speed AF operation during Live View shooting
The K-70 employs PENTAX’s first Hybrid AF system during Live View autofocus operation. By positioning a contrast-detection AF sensor with superior focusing accuracy and a phase-matching AF sensor on the image sensor’s surface, this innovative hybrid system optimizes the benefits of both AF systems to assure high-speed, pinpoint AF focusing on the subject.
Dustproof, weather-resistant body perfect for outdoor photography
The K-70 boasts a fully weather and cold proof design to resist water, fog, snow, sand and dust, for top performance in extreme field conditions. It has been designed for active outdoor shooting through a complete design review of the mode dial and control buttons as well as new grip design that provides a firm hold of the camera body even with a gloved hand. The outdoor-friendly LCD monitor features a brightness level that can be instantly adjusted to the lighting level of any shooting location, as well as a red-lighted monitor display function, which is easier on the photographer’s eye when shooting in dark locations such as during astronomical photography.
High-precision autofocus system with the SAFOX X module
The high-precision SAFOX X AF sensor module assures responsive, dependable autofocus operation. With its 11 sensors including nine cross-type sensors in the middle, this AF module assures pinpoint focus on the subject at a minimum brightness level as low as -3 EV. The speed of autofocus response has been improved, especially at low-illumination levels. By improving the algorithm for moving objects, the focusing accuracy in the AF-C mode has been enhanced. The K-70 assures outstanding AF tracking performance with subjects on the move, thanks to such advanced features as the Select-area Expansion function, which automatically refocuses on a moving subject after it moves away from the initial point, with the help of the neighboring points, and an AF Hold function that maintains the initial in-focus point even when the module loses sight of the subject.
PENTAX-original shake-reduction system featuring the Pixel Shift Resolution System
In-body SR mechanism
The K-70’s in-body shake reduction (SR) mechanism effectively compensates for camera shake up to 4.5EV steps. The K-70’s SR unit has a flexible design that shifts the image sensor unit in all directions, providing a host of handy shooting functions, including ASTRO TRACER, which simplifies advanced astronomical photography when used in combination with the optional O-GPS1 Unit.
Pixel Shift Resolution System with motion correction function
The Pixel Shift Resolution System captures 4 images of the same scene by shifting the image sensor by a single pixel for each image, and then synthesizes them into a single composite image. The result is exceptional detail and true-to-life colour accurate images. This system also has a motion correction function which automatically detects a moving object during the synthesizing process to accommodate a wider range of scenes and subjects.
Innovative AA filter simulator to minimize moiré
By applying microscopic vibrations to the image sensor unit at the sub-pixel level during image exposure, the K-70's AA (anti-aliasing) filter simulator provides the same level of moiré reduction as an optical AA filter. This innovative simulator lets the user switch the AA filter effect on and off, and adjust the level of the effect.
Optical viewfinder with nearly 100-percent field of view
The K-70 incorporates a glass prism finder featuring the same optics and coatings as those used in higher-level models. With a nearly 100-percent field of view and a magnification of approximately 0.95 times, it provides a wide, bright image field for easy focusing and framing.
High-speed shutter to capture fast-moving subjects in crisp focus
With a top shutter speed of 1/6000 second, the K-70 captures sharply focused images, even with fast-moving subjects. Coupled with its high-speed continuous shooting function with a top speed of approximately six images per second, making it ideal for capturing fast moving subjects at sporting events or wildlife photography.
Upgraded Full HD movie recording
The K-70 captures high-resolution, Full HD movie clips (1920 x 1080 pixels; 60i/30p frame rate) in the H.264 recording format. In combination with compatible lenses, it allows the user to 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 a proper exposure level even in fluctuating lighting conditions during movie recording. It also provides a host of distinctive visual effects for movie production, including the 4K Interval Movie mode that connects a series of 4K-resolution still images at a fixed interval to create a single movie file, and a Star Stream mode to fade in and out the traces of stars to recorded movies.
* During movie recording, the Continuous AF (AF-C) mode can be used in combination with the HD PENTAX-DA 55-300mm F4.5-6.3ED PLM WR RE or smc PENTAX-DA 18-135mm F3.5-5.6ED AL[IF] DC WR lens.
** During movie recording, the aperture control function is available only in combination with the HD PENTAX-DA 55-300mm F4.5-6.3ED PLM WR RE lens.
Vari-angle LCD monitor for easy image viewing from all angles
The vari-angle LCD monitor extends the freedom of shooting position from high angle to ground level view. The 3.0 inch, 921K dot Air Gapless LCD construction ensures good visibility of displayed images, even outdoors.
Wireless LAN connection to support smartphone operation
The PENTAX K-70 provides a host of wireless LAN (Wi-Fi) functions to support operations using smartphones and tablet computers. By installing the dedicated Image Sync application in a mobile device, the user can remotely check the Live View image, capture still images, and adjust such camera settings as aperture, shutter speed and ISO sensitivity to the desired level through the mobile device. It is even possible to download captured images onto the mobile device, then upload them on social networking service websites.
