Press Release:


GOLDEN, CO (September 16, 2009) : PENTAX Imaging Company redefines the entry-level digital SLR category with the introduction of the K-x digital SLR.  This latest PENTAX camera offers high-end features including Live View and HD video.  And, since there’s no rule that SLR cameras must come in black only, the K-x will be available in a choice of white or black, as well as special, limited edition red and navy.

Priced at $649.95 USD (for body with DA L 18-55mm lens), the extremely compact and lightweight PENTAX K-x forges ahead on the trail initiated by the popular PENTAX K2000.   With a one-handed shooting design and simple, easy-to-use operation, the K-x is perfect for users stepping up from a point and shoot digital camera to their first digital SLR.

The PENTAX K-x offers photographic performance that challenges higher class DSLR models and offers several features that set this camera apart in the entry-level category:

All combined, the PENTAX K-x is the perfect camera for new digital SLR camera users as well as an ideal backup camera for more experienced photographers.

Along with the K-x, PENTAX announced the smc PENTAX DA L 55-300mm F4-5.8 ED super-telephoto zoom lens.  This lens will be exclusive to a K-x Twin Lens Kit package consisting of a K-x body, this new lens and the smc PENTAX DA L 18-55mm F3.5-5.6 lens.  The lightweight design of this zoom lens offers the exceptional optical performance found in all PENTAX lenses for super-telephoto photography with the K-x and other PENTAX digital SLR camera bodies.

The PENTAX K-x is now available for pre-order in black or white.  Limited edition colors of red and navy will become available at select locations to be announced. 

The PENTAX  K-x (in black and white) will ship in October 2009 in three configurations: options: 


12.4 effective megapixels
The K-x incorporates a newly developed CMOS image sensor to assure high-speed image data readout and more flexibility with varying ISO sensitivity levels. With approximately 12.4 effective megapixels, this image sensor accurately reproduces true-to-life images with fine detail and rich color depth. The
K-x offers a wide sensitivity range between ISO 200 and ISO 6400 and allows users to expand the sensitivity range between ISO 100 and ISO 12800 via a custom function to offer greater creative freedom to photographers.

Compact, lightweight body
The PENTAX K-x is one of the most compact, lightweight digital SLR cameras in its class. The   stainless-steel chassis and overall design offer a space-efficient layout.

Widescreen HD movie recording at 1280x720 pixels at a cinematic 24 frames per second (720p24)
The PENTAX K-x movie recording function*1 captures 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. Compatible with every PENTAX interchangeable lens ever made, the Video Capture mode opens a new world of creativity for PENTA K-x owners. 

PENTAX-original SR mechanism for sharp, blur-free images
The K-x features the PENTAX-developed Shake Reduction mechanism that effectively compensates for the adverse effects of camera shake by as much as four shutter steps. This innovative mechanism extends its benefits to all PENTAX interchangeable lenses — even those designed for film-format cameras.*2  With this SR mechanism, the K-x produces sharp, blur-free images even under demanding conditions such as telephoto lens photography, shooting in dark or low-light setting without a flash illumination, and sunset scenes.

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. This is the fastest of all entry-class models. The K-x also features a more reliable shutter unit, which passed a demanding action test of more than 100,000 shutter releases.   The top shutter speed of 1/6000 second allows the photographer to preserve sharp, crisp images of fast-moving subjects.

High-performance, high-speed PRIME II imaging engine
The K-x features the newly developed PRIME (PENTAX Real IMage Engine) II, that is an upgrade of the original PRIME imaging engine. This new imaging engine offers greater data processing speed and enhanced capability to produce higher-quality images with richer, more accurate color rendition, as well as faster transmission speed of movie data.

Live View function with Face detection of up to 16 faces
In addition to the camera’s viewfinder, the K-x features a Live View function that allows users to view subjects on the LCD monitor during shooting.   The K-x also offers a choice of three different focusing modes in Live View: 

Innovative Image Processing Functions

Digital Filter function
The K-x’s digital filter function allows users to process recorded images in a variety of creative ways within the camera and produce highly creative visual expressions. With a choice of 16 different filters including Color Extract, Retro, Soft, Starburst, Toy Camera, and more (including a custom filter for building multiple effects), photographers may apply multiple filters to a single image for customized effects.

Cross Process mode
The K-x features a new Cross Process mode that automatically and randomly adds finishing touches to  exposures to create eye-catching images with unique, intriguing colors (just like images treated with Cross Process*3 in film photography).  This mode adds a whimsical element  to digital photography since photographers don’t know the results until the captured image is actually displayed on the camera’s LCD monitor.

High-precision 11-point AF sensor
The high-precision, wide-frame SAFOX VIII autofocus system of the K-x features 11 sensor points (with nine cross-type sensors positioned in the middle) to automatically capture even off-centered subjects in sharp, crisp focus.   Photographers also may select one of the sensors as a focusing point to accommodate specialized applications.

Additional features

*1 When the PENTAX K-x’s AV output terminal is used, movie clips are viewed 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).
*2 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.
*3 A film development technique that takes advantage of unconventional film developers to create a distinctive finishing touch with intriguing colors.
