24 effective mega-pixels in an APS-C sized CMOS sensor
Designed for the demanding photographer, the K-3 features 24 effective megapixels in an APS-C sized CMOS sensor for outstanding high resolution imagery. By coupling this sensor with a newly developed PRIME III imaging engine with high-efficiency noise and image processing capacities and an anti-aliasing filter-less design, the K-3 delivers high-resolution, fine-gradation images.

Selectable Anti-Aliasing Filter
Enjoy the world’s first selectable anti-aliasing filter, giving the user the ability to easily toggle anti-aliasing functionality on or off, for supreme resolution and zero limitations. This breakthrough technology eliminates the need to commit to either supreme resolution or superior moiré control, by providing both options in a single camera body. Newly developed for the K-3, the anti-aliasing simulator* applies microscopic vibrations to the image sensor unit at the subpixel level during image exposure, generating the same level of moiré-reduction effect as an optical anti-aliasing filter. * This function is most effective with a shutter speed of 1/1000 second or slower. This function is not available during HDR shooting.

-
Multi-pattern white balance
When shooting scenes that include multiple light sources, such as sunlight and shade or flash, light sources are recognized automatically and the image is separated into different areas. White balance is adjusted separately in each area according to the different light sources to achieve optimal color reproduction.
-
PENTAX PEF and Adobe DNG files
Native support for both PENTAX PEF and Adobe DNG 14 bit RAW files, including the ability to retrieve RAW data from JPG files if still present in buffer memory.
-

Fastest continuous shooting at 8.3FPS
Never miss a single moment with an incredibly fast frame rate of 8.3 FPS, for extreme action capture and demanding high performance shooting. With a maximum 1/8000 second shutter speed, freeze even the fastest action without subject movement blur--rated for 200,000 cycles. The K-3 continuously records as many as 22 images in the RAW format or 60 images in the JPEG format* in a single sequence. This is made possible through the use of several innovative technologies, including a high-speed, high-accuracy control mechanism that regulates the shutter, mirror and diaphragm independently; a damper mechanism that effectively minimizes mirror shock; and a high-speed data transmission system incorporated in the PRIME III imaging engine. * JPEG Recorded Pixels：L, JPEG Quality：★★★
