The K-5 inherits the exceptional reliability, user-friendly operation, array of advanced features and compact, lightweight body of its predecessor, the highly acclaimed K-7, yet is more resourceful and flexible in photographic expression. The K-5 features a new 16.28 megapixel sensor, and has a wide sensitivity range from ISO 80 to 51200 (when expanded via a custom function). With a much faster autofocusing speed, an upgraded HDR (High Dynamic Range) function that is now usable in handheld shooting and full HD-proportion movie recording at 1920 x 1080 pixels, the K-5 is designed to be more functional and maneuverable in every detail, and more capable of responding to the discriminating demands of advanced photographers.

K-5 Features

The K-5 incorporates a newly designed 16.28 megapixel CMOS sensor which assures high-speed image data readout. Combined with the reliable PRIME II Imaging Engine, the K-5 produces high-resolution, rich-gradation digital images while suppressing digital noise to a minimum. It offers a wide sensitivity range, from ISO 100 to 12800, which can be expanded to ISO 80 to 51200 via a custom function.
The sophisticated new-generation, wide-frame SAFOX IX+ autofocus system with 11 sensor points (with nine cross-type sensors positioned in the middle) has completely redesigned optics and uses the light source in its calculations to improve the accuracy of autofocus operation. It offers a choice of 3 shutter-release options allowing the photographer to choose the best option for their subject. Thanks to the new image sensor and a more sophisticated algorithm, the K-5’s Contrast AF mode assures better performance and greater focusing speed than before during Live View shooting. With the addition of a Golden Section display, the K-5 offers a choice of three different grid patterns to facilitate image composition.
The K-5’s high-speed continuous shooting mode records as many as 30 images (in JPEG format) in a single sequence at a maximum speed of approximately seven images per second, allowing the photographer to shoot sharp, crisp images of active, fast-moving subjects with great ease.
Despite its compact dimensions, the K-5 is exceptionally solid and durable, with a body made of sturdy, yet lightweight magnesium alloy, and a chassis of highly rigid cold rolled stainless steel. Thanks to the inclusion of 77 special seals in the body, it also boasts a dustproof, weather-resistant and cold-resistant construction, assuring reliable operation, even in harsh environments and at temperatures as low as -10°C.
The K-5 pentaprism finder with nearly 100% field of view and approximately 0.92-times magnification (with a 50mm F1.4 lens at infinity), provides a better view of the image field and improves the accuracy and speed of focusing and image composition. The renowned Natural-Bright-Matte focusing screen assists with manual-focus operation.
The PENTAX-developed SR (Shake Reduction) mechanism effectively compensates the adverse effect of camera shake by as much as four shutter steps, assuring sharp, blur-free images even under demanding shooting conditions. This innovative mechanism is compatible with almost all existing PENTAX interchangeable SLR lenses – both old and new. The K-5 also features an auto level compensation function to assure effortless adjustment of horizontal alignment, and a composition adjustment function to automatically compensate for the camera’s inclination during handheld shooting – vertically, horizontally, and in the direction of rotation.
The K-5 captures beautiful, true-to-life movie clips in 16:9 Full HD proportions at a frame rate of 25 frames per second. This extends many the benefits of high-quality SLR photography to the world of movie shooting. For instance, reduce the depth of field to make a subject stand out, or use different interchangeable lenses to create distinctive visual effects.
Innovative image-processing functions to produce distinctive photographic expressions
1. Custom image function
  The K-5 offers a choice of nine custom image modes, which allows you to easily select a desired finishing touch for a particular image.
2. Versatile digital filter function
  The digital filter function allows you to process recorded images in a variety of creative ways to produce highly creative visual expressions without the need of a computer. You not only have a choice of 18 different filters, but can also apply different filters one after another to a single image to create more visual effects.
3. Cross process modes
  The unique cross process mode, in which the camera automatically shifts photographic parameters for each exposure, creates eye-catching images with unique, dramatic colours - just like pictures treated with the cross process in film photography.
4. Upgraded HDR (High Dynamic Range) function
  The HDR (high dynamic range) function creates one composite image with an extra- wide gradation range from three images with different exposures, without the need of a computer application. It offers a choice of auto, standard and expanded (at three levels) modes to accommodate different creative effects. Thanks to the introduction of Auto Align function, you can now take advantage of this creative tool even with handheld shooting.
5. In Camera RAW processing to JPEG or TIFF format images
  The K-5 features in-camera RAW processing to JPEG or TIFF-format images with full adjustment of image parameters such as custom picture style, white balance, sensitivity, high ISO noise reduction, lens distortion and colour space.
