HOYA CORPORATION PENTAX Imaging Systems Division is pleased to announce the launch of the PENTAX K-5 lens-interchangeable digital SLR camera. Encased in a compact but solid, functional body, this new model comes equipped with a host of advanced photographic tools for the easy creation of diversified visual expressions, while demonstrating much higher standards of image quality, data processing speed and operability than previous models.
Developed using the highly acclaimed PENTAX K-7 (introduced to the market in June 2009) as its base, the K-5 inherits the exceptional reliability, user-friendly operation, array of advanced features and compact, lightweight body of its predecessor, yet it is more resourceful and flexible in photographic expression. Coupling a new high-speed, low-noise CMOS image sensor with the high-performance PRIME II imaging engine, it produces super-high-resolution, rich-gradation digital images with approximately 16.28 effective megapixels, even when shooting in the continuous shooting mode at a maximum speed of approximately seven images per second. It also offers an extra-wide sensitivity range between ISO 80 and ISO 51200 (when expanded via a custom function) and Full HD-proportion movie recording at 1920 x 1080 pixels to expand the boundaries of high-quality visual presentation. Adding other improvements and refinements — such as much-faster autofocusing speed, an upgraded HDR (High Dynamic Range) function now usable in handheld shooting, and better operability through an overall review of the design and shape of all components — 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 amateurs than previous models.
High-resolution, low-noise, true-to-life image reproductionThe K-5 incorporates a newly designed CMOS image sensor with a wide image-sensitive area measuring 23.7mm by 15.7mm. It assures high-speed image data readout much faster than that of previous sensors. By coupling this image sensor — equivalent in performance and data processing speed to the image sensor incorporated in the PENTAX 645D medium-format digital camera — with the reliable PRIME (PENTAX Real Image Engine) II imaging engine, the K-5 produces super-high-resolution, rich-gradation digital images with approximately 16.28 effective megapixels, while suppressing annoying digital noise to a minimum. The K-5 also offers a wide sensitivity range between ISO 100 and ISO 12800. This range can be expanded by the user from ISO 80 to ISO 51200 via a custom function to accommodate applications intended for more creative expressions, such as open-aperture shooting using a large-aperture lens, and indoor and nighttime shooting with incident light only.
High-speed continuous shooting at approximately seven images per secondThe K-5’s high-speed continuous shooting mode records as many as 30 images (in the JPEG recording format) in a single sequence at a maximum speed of approximately seven images per second, allowing the photographer to preserve sharp, crisp images of active, fast-moving subjects — such as sports players, stage performers and wildlife — with great ease.
Responsive, high-precision AF systemThe K-5 features a new-generation, wide-frame SAFOX IX+ autofocus system with 11 sensor points (with nine cross-type sensors positioned in the middle). This sophisticated AF system has completely redesigned optics, and factors the light source at the time of shooting into its calculations to improve the accuracy of autofocus operation. It also offers a choice of shutter-release options — between focus priority and release priority in the AF.S (single) advance mode, or between focus priority and speed priority in the AF.C (continuous) advance mode — to make the photographer better equipped for varying photographic requirements. The K-5 is also equipped with a spotbeam projector to assist the AF system in poorly lit locations.
Compact, solid, functional camera bodyDespite its compact dimensions, the K-5 is built to be exceptionally solid and durable, with a body of sturdy yet lightweight magnesium alloy, and a chassis of highly rigid 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 under harsh environment, and at temperatures as low as -10°C. It also features a reliable shutter unit that provides a top shutter speed of 1/8000 second and the outstanding durability to withstand as many as 100,000 shutter releases. Despite all these features, the K-5 still offers an extremely compact, functional body, because PENTAX has applied all its years of experience and expertise in camera downsizing that it accumulated since the earliest days of film-format SLR cameras.
Bright, clear optical viewfinder with 100% field of viewThe K-5 features a pentaprism finder with nearly 100% field of view and at approximately 0.92-times magnification (with a 50mm F1.4 lens at infinity) to provide a better view of the image field and improve the accuracy and speed of focusing and image composition. It also comes with the renowned Natural-Bright-Matte III focusing screen to assist the photographer with manual-focus operation. The K-5’s bright, clear viewfinder assures greater visibility in outdoor shooting — especially when using a telephoto lens — allowing the photographer to better concentrate on the subject and image composition.
Effortless Live View shootingThanks to a 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.
PENTAX-original SR mechanism with user-assisting optionsThe K-5 features the PENTAX-developed SR (Shake Reduction) mechanism, which effectively compensates the adverse effect of camera shake by approximately 2.5 to 4 shutter steps, to produce sharp, blur-free images. This innovative mechanism works with almost all PENTAX interchangeable lenses — even those designed for film-format cameras.* Thanks to the SR mechanism’s flexible design, which tilts the image sensor unit in all directions, the K-5 offers several useful features to assist the photographer during shooting. These include an auto level compensation function to assure high-precision framing and effortless adjustment of horizontal alignment, and an image-composition fine-adjustment function to automatically compensate for the camera’s inclination during handheld shooting — vertically, horizontally, and in the direction of rotation.
* Lenses compatible with this mechanism: PENTAX K-, KA-, KAF-, KAF2- and KAF3-mount lenses; screw-mounted lenses (with an adapter); and 645- and 67-system lenses (with an adapter). Some functions may not be available with certain lenses.
Recording of Full HD-proportion movies (1920 x 1080 pixels, 25 frames per second)The K-5 captures beautiful, true-to-life movie clips in 16:9 Full HD proportions (1920 x 1080 pixels) at a frame rate of 25 frames per second.** This extends many of the benefits of high-quality SLR photography to the world of movie shooting: For instance, users can reduce the depth of field to make a subject stand out, or use different interchangeable lenses to create distinctive visual effects. The K-5 also provides greater possibilities in visual presentation in movies***, especially through the application of custom images and digital filters.
** Movie recording may be terminated when a memory card with low transfer rate is used in the K-5.
*** The number of frames may vary when in certain image processing mode.
Innovative image-processing functions to produce distinctive photographic expressions
**** A film development technique that uses unconventional film development to create a distinctive finish with dramatic, stylized colors.
***** Under testing conditions prescribed by PENTAX, when using a rechargeable D-LI90 lithium-ion battery with no flash discharges.
