Pentax's K-r digital SLR. Photo provided by Pentax Imaging Co. Pentax K-r: twelve megapixel, 6 fps digital SLR
(Thursday, September 9, 2010 - 00:01 EDT)

Pentax Imaging Co. has today announced its latest digital SLR model, and a sibling for its existing entry-level K-x and flagship K-7 digital cameras -- the Pentax K-r.

The K-r includes a couple of firsts for Pentax's digital SLR lineup, as well as a number of important features that set it above the K-x, alongside which it will continue to be sold for the time being. Perhaps the most noteworthy upgrade in the Pentax K-r digital camera is its viewfinder focus point display, a feature whose conspicuous absence we questioned in our K-x review. The Pentax K-r also incorporates a larger, higher-resolution LCD display like that previously seen in the K-7.

Among the new features for the K-r, it sets a new high for burst shooting speed in a Pentax digital SLR, at six frames per second. (Burst depth is also greater than the K-x, although not as deep as for the K-7.) There's also IrSimple infrared connectivity, making its debut in a Pentax DSLR (and we think unique among any DSLR, unless something's slipped our mind.) Maximum expanded ISO sensitivity from a newly developed sensor is also increased to ISO 25,600 equivalent. The Pentax K-r digital camera also offers dual battery support in-body -- either a provided lithium ion rechargeable pack, or four AA cells with an adapter. There's also support for SDXC cards on the way, although this will arrive in a promised firmware update after commercial availability.

The Pentax K-r is also the company's first to offer microalignment for HDR images, a Bleach Bypass custom image mode, Sketch and Posterization filters, the ability to use filters during high-def movie recording.

Body-only pricing for the K-r is set at US$800, with availability from October 2010. In addition, three kit bundles will be available, including a either one or two DA-L lenses at a pricetag of $850 to $1,000, depending on the specific lens models. For more details, read our Pentax K-r preview.

Simultaneous with the Pentax K-r announcement, the company has also unveiled its new smc PENTAX DA35 mm F2.4 AL, also available from October, and affordably priced at US$219.95.

High-quality, true-to-life image reproduction
The K-r incorporates a new generation CMOS image sensor with 12 megapixels and the high-performance PRIME (PENTAX Real Image Engine) II imaging engine for accurate and high-speed data processing equal to that of upper-level PENTAX digital SLR models for high-quality images.

The camera also offers a wide sensitivity range between ISO 200 and ISO 12800 that may be expanded from ISO 100 to ISO 25600 via a custom function.

Compact, lightweight body
Even with the 23.6mm x 15.8mm image sensor, the K-r features a compact, lightweight, stainless-steel chassis with in-body Shake Reduction in a space-efficient design.

High-speed continuous shooting at approximately six images per second
The K-r's high-speed continuous shooting mode records as many as 25 images (in JPEG recording format) in a single sequence at a maximum speed of approximately six images per second (fastest of all entry-class models) for sharp, crisp images of fast-moving subjects.

High-precision AF system
The K-r's high-precision, wide-frame SAFOX IX autofocus system features 11 sensor points (with nine cross-type sensors positioned in the middle) for pinpoint focus on the subject. The K-r is also equipped with a spotbeam projector to assist the AF system in poorly lit locations. Accuracy and speed of contrast AF operation during Live View shooting is enhanced with a new-generation image sensor and drastic upgrading of AF algorithms.

Bright, clear optical viewfinder
The PENTAX-original finder optics and the renowned Natural-Bright-Matte focusing screen ensure the K-r's viewfinder offers a bright, clear subject image at 0.85X magnification and with a 96% field of view. The viewfinder offers excellent visibility even in bright outdoor locations and provides delay-free, real-time display of the subject's image. This is helpful when shutter release timing is critical such as in sports photography. The in-focus point is indicated as a red point in the viewfinder for at-a-glance confirmation.

Large, easy-to-view 3 inch LCD monitor with wide-view design and approximately 921,000 dots
The K-r features a large, high-resolution color LCD monitor with approximately 921,000 dots and its wide-view design assures a clear view of the monitor image from approximately 170 degrees horizontally and vertically, making it particularly useful in low- and high-angle applications during Live View shooting.

Versatile dual-power-source design
In addition to the rechargeable lithium-ion battery, which allows the photographer to capture approximately 560 images with a single recharge,* the K-r can also be powered by four AA-size batteries using optional AA Battery Holder D-BH109.
* Based on the PENTAX in-house testing conditions conforming to the CIPA standards, using a rechargeable D-LI109 Lithium-Ion Battery.

PENTAX-original Shake Reduction mechanism for sharp, blur-free images
The K-r features the PENTAX-developed SR (Shake Reduction) mechanism, which effectively compensates the adverse effect of camera shake by up to approximately four shutter steps. This innovative mechanism extends its benefits to almost all PENTAX interchangeable lenses — even those designed for film-format cameras.* The K-r 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 flash illumination, and shooting sunsets.
* 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.

Innovative image-processing functions to produce distinctive photographic expressions

  1. Custom Image function for distinctive finishing touches The K-r features the Custom Image function to allow users to select a desired finishing touch for a particular image with a choice of nine custom image modes including Bleach Bypass, which is designed to create a dramatic visual effect used in motion pictures.

  2. Versatile Digital Filter function The K-r's Digital Filter function allows users to process recorded images in a variety of creative ways and produce highly creative visual expressions — without a computer. Users may choose from 18 filters, including a new Starburst, Sketch and Posterization and may now apply filter upon filter, one after another, to an image for more creative results.

  3. Cross Process mode with three options The K-r features the unique Cross Process mode that automatically shifts photographic parameters for each exposure to create eye-catching images with dramatic colors (as with photographs treated with the cross process* in film photography). In addition to "Random", where the results are unpredictable until the image has been processed, users now have two new options: "Preset" with three different sets of preset parameters; and "Favorite" with user-input parameters. *A film development technique that uses unconventional film development to create a distinctive finish with dramatic, stylized colors.

  4. Improved High Dynamic Range function The K-r features the High Dynamic Range function to create one composite image with an extra-wide gradation range from three images with different exposures without a computer. Users may choose from Auto, Standard and Expanded (at three levels) modes to accommodate different creative intentions.
    An Auto Align function allows use even with handheld shooting.

High-speed infrared data transmission system
The K-r is the first PENTAX digital SLR camera equipped with the IrSimple™ high-speed infrared data transmission system, which allows users to transfer image data to IrSimple-compatible digital devices and post their K-r images on the web via a cellular phone. This also allows users to exchange image data between two K-r cameras and play a simple match game using image Exif data (such as aperture or shutter-speed values) to judge images and offer techniques and suggestions for better images.

High-quality, HDTV-proportion movie recording at 1280 x 720 pixels and at 25 frames per second
The K-r 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 25 frames per second. This extends many benefits of high-quality SLR photography to the world of movie shooting: For example, users may reduce the depth of field to make a subject stand out, or use different interchangeable lenses to create distinctive visual effects. The K-r also assures a greater possibility of visual presentation in movies — either through the application of digital filters, such as Toy Camera and Retro, to add specific visual effects during shooting, or through the use of various movie-editing functions after shooting.
*When the PENTAX K-r'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).

Additional Features:

  • User-friendly layout of essential control buttons and levers, all positioned on the camera's grip side for quick, effortless access by the photographer's right hand.

  • Auto Picture mode, for effortless, automatic selection of the most appropriate shooting mode, even during Live View shooting.

  • Versatile white balance control, featuring a new CTE mode designed to emphasize the dominant color components of the captured images which works best with scenes such as sunset.

  • Automatic compensation of distortion and lateral chromatic aberration (available only with DA-,DFA- and FA Limited-series lenses).

  • PENTAX Digital Camera Utility 4 software package, with RAW-data processing and browser applications.
