Get professional h.264 video capture, dual memory card slots, extreme image capture, plus PENTAX weather sealing in a stunning magnesium alloy body. So you never have to stop shooting.

24 MP in an APS-C sized CMOS sensor

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 that features high-efficiency noise and image processing capacities, and an anti-aliasing filter-less design, the K-3 delivers high-resolution, fine-gradation images.

fastest continuous shooting at 8.3 fps

Perfect for extreme action capture and demanding high performance shooting. With a maximum 1/8000 second shutter speed, you can 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, thanks to 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:★★★

selectable anti-aliasing filter

The world’s first selectable anti-aliasing filter lets you easily toggle anti-aliasing functionality on or off, for supreme resolution and zero limitations. No need to commit to either supreme resolution or superior moiré control; both options are in this single camera body. 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.

professional h.264 video

Enhance your video recording experience with full HD movie capture in the h.264 format (60i/50i/30p/24p). Switch from still image to video recording with the flip of a dedicated switch. Equipped with a headphone terminal and stereo microphone terminal for external microphone connection. You can also adjust the audio recording level manually and monitor sound levels during recording.

SAFOX 11 autofocus module

The newly designed SAFOX 11 autofocus module maximizes 27 AF sensors and a vast light sensitivity range of –3EV to +18EV. The new focus module includes 25 cross sensors and three AF sensors dedicated to low-light focusing.

real time scene analysis with 86,000 pixel sensor

The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor and improved algorithms that further enhance accuracy of exposure, white balance and autofocusing.

dual SD card slots

Dual SD card slots allow for greater memory card flexibility, for separation of JPG and RAW files, and for use with new Flu-card technology.

With installation of the optional, dedicated 16 GB Flu-card, you can remotely change settings such as aperture, shutter speed and ISO, shift the AF focus point, release the camera shutter, check Liveview image, and browse and download images to mobile devices and PC. Eye-fi Wireless and standard SDX Memory cards also compatible.
