The Pentax K-3 features a host of advanced functions and user-friendly features to optimize image quality, operability and maneuverability under demanding shooting conditions.
High-resolution images with the 24 megapixel brand-new sensor
The Pentax K-3 is equipped with a new APS-C-size CMOS image sensor (23.5mm×15.6mm) with approximately 24 effective megapixels. 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-free design, the K-3 delivers high-resolution, fine-gradation images.
It also offers a top sensitivity of ISO 51200, for the photography of detailed images even under extremely poor lighting conditions, and to simplify handheld shooting of nightscapes.
Compact, solid body with dustproof, weather-resistant construction
The K-3’s exterior casing is made of sturdy yet lightweight magnesium alloy. Thanks to the inclusion of 92 special sealing parts in the body, it boasts a dustproof, weather-resistant and cold-resistant construction, assuring solid operation at temperatures as low as -10°C.
Large, easy-to-view 3.2-inch LCD monitor
On its back panel, the K-3 features a newly designed 3.2-inch high-resolution LCD monitor with approximately 1,037,000 dots (in a 3:2 aspect ratio). In addition to its wide-view design, this monitor also features a protective tempered-glass front panel for added durability, and a unique air-gapless construction in which the air space between LCD layers is eliminated, effectively reducing the reflection and dispersion of the light to improve visibility during outdoor shooting. During playback, the K-3 even allows the user to check recorded images at life-size magnification.
Optical viewfinder for a nearly 100% field of view
The K-3’s glass prism has been treated with a new coating that was designed to improve reflectance, resulting in a much brighter viewfinder image. The eyepiece optics have been completely redesigned to assure an approximately 0.95-times viewfinder magnification to provide a broader image field, making it easier for the photographer to confirm the subject’s focusing status and compose the image.
Full HD movie recording with creative tools
The K-3 captures beautiful Full HD movie clips (1920 × 1080 pixels; 60i/30P frame rate) in the H.264 recording format, which assures flawless, high-quality movies even with fast moving subjects. It also comes equipped with a stereo mic terminal for external microphone connection and a headphone terminal. The user can even adjust the audio recording level manually and monitor sound levels during microphone recording. In addition to a variety of creative special-effect modes,* the K-3 also provides an upgraded interval movie mode, which captures a series of 4K-resolution movie clips (3840 × 2160 pixels) at a fixed interval.
High-speed continuous shooting
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, at a maximum speed of approximately 8.3 images per second. This has been 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.
Smartphone support functions
By installing the optional FLU CARD FOR PENTAX 16GB memory card in the K-3, the user can release the K-3’s shutter, check the live-view image, and browse and download the images recorded on the card using a smartphone. (This software supports smartphones operating on iOS6 or later and Android 4.2 or later).
