HOYA CORPORATION PENTAX Products is pleased to announce the launch of the PENTAX K-x, a new lens-interchangeable digital SLR camera. This new model combines solid photographic performance with a wide array of advanced features, including Live View function and high-quality movie recording, extending high-quality digital SLR photography to all users. Its compact, lightweight body also enhances portability and maneuverability, making it ideal for many different photographic occasions.
The K-x design is based on the PENTAX K-m, an entry-class digital SLR camera launched in October 2008 that early on gained popularity for its compact, lightweight body and simple, user-friendly operations. With the addition of a newly designed CMOS image sensor and an upgraded high-performance imaging engine, the K-x offers outstanding photographic performance at nearly the same level as upper-class models. This includes high-resolution, fine-detailed images delivered by approximately 12.4 effective megapixels, super-high-sensitivity photography and high-speed continuous shooting. The K-x also features an array of advanced functions, including Live View shooting and movie recording. It also provides a pair of handy functions designed to produce highly personalized images with great ease: an upgraded digital filter function to accommodate more sophisticated image processing, and a new cross process mode to produce unexpected, eye-catching finishing touches with unique, intriguing colors. The K-x is not only the perfect camera for first-time digital SLR camera users, but also serves as the ideal backup camera for more experienced photographers.
Along with the K-x, PENTAX will also launch the smc PENTAX-DA L 55-300mmF4-5.8ED super-telephoto zoom lens as part of the K-x Twin Lens Kit package. This zoom lens was designed to be lightweight without compromising the exceptional optical performance common to all PENTAX lenses, making super-telephoto photography easier and smoother for K-x users.
High-quality image reproduction
Compact, lightweight body
Despite the incorporation of the large 23.6mm x 15.8mm image sensor, the K-x is one of the most compact, lightweight digital SLR camera in its class. This is due to the combination of a compact, lightweight stainless-steel chassis, a downsized in-body shake reduction mechanism, and state-of-the-art, highly-integrated packaging methodologies that assure the most space-efficient positioning and layout of various parts.Live View function, with Face detection of up to 16 faces
The K-x features the Live View function, which allows the user to view the image on its LCD monitor during shooting, just as for a digital compact camera. The K-x also offers a choice of three different focusing modes during Live View shooting: Contrast AF, which optimizes the focus based on the subject’s contrast; Face Detection AF, which automatically detects up to 16 faces, selects the main subject’s face from multiple faces, then captures it in sharp focus; and Phase Difference AF, which uses the AF sensor positioned in the camera body to optimize focus on the subject.High-quality recording at 1280 x 720 pixels, with HDTV-proportion movie recording at 24 frames per second
The K-x provides a movie recording function* which captures beautiful, true-to-life movie clips in 16:9 high-definition TV proportions (1280 x 720 pixels) at a frame rate of 24 frames per second. This extends the benefits of high-quality SLR photography to the world of movie shooting: For example, reduce the depth of field to make a subject stand out, or use different interchangeable lenses to create distinctive visual effects.* When the PENTAX K-x's AV output terminal is used, movie clips are output at normal resolution. The data must be transferred to a PC for the playback of movie clips at high-definition TV proportions (1280 x 720 pixels).
PENTAX-original SR mechanism for sharp, blur-free images
The K-x features the PENTAX-developed SR (Shake Reduction) mechanism, which effectively compensates the adverse effect of camera shake by as much as approximately four shutter steps. This innovative mechanism extends its benefits to almost all PENTAX interchangeable lenses — even those designed for film-format cameras.** Thanks to this mechanism, the K-x produces sharp, blur-free images even under demanding conditions prone to camera shake, such as when using a telephoto lens, shooting in the dark without a flash illumination, and taking pictures of sunset scenes.** 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.
High-speed continuous shooting at approximately 4.7 images per second
The K-x’s high-speed continuous shooting mode records as many as 17 images (in JPEG recording format) at a maximum speed of approximately 4.7 images per second — the fastest of all entry-class models. The K-x also features a new, reliable shutter unit, which proved its dependability and ruggedness through a demanding action test of more than 100,000 shutter releases. Its top shutter speed of 1/6000 second allows the photographer to preserve sharp, crisp images of fast-moving subjects.Innovative image processing functions to produce distinctive photographic expressions
*** A film development technique that takes advantage of unconventional film developers to create a distinctive finishing touch with intriguing colors.
High-precision 11-point AF sensor
The K-x’s high-precision, wide-frame SAFOX VIII autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) to automatically capture even off-centered subjects in sharp, crisp focus. The photographer can also select one of the sensors as a focusing point to accommodate specialized applications.Other features
