11-point wide-frame AF to capture off-center subjects in crisp focus
The sophisticated K100D SAFOX VIII autofocus system features 11 sensor points (with nine cross-type sensors) to automatically focus on the subject with utmost precision, even when it is positioned off center. The in-focus sensor point is automatically superimposed in red in the viewfinder for at-a-glance confirmation. This high-precision AF system offers a choice of two AF modes: the conventional single AF, and the continuous AF, which maintains focus on the moving subject as long as the shutter release button is pressed halfway down. (The continuous AF mode is selectable by the user only when P, Tv, Av, M, or B is selected as a shooting mode on the mode dial. This mode is automatically activated by the camera when the Auto Picture Program, or one of the Picture or Scene modes, is selected.)

Auto sensitivity control up to ISO equivalent 3200
The K100D features an auto sensitivity control function, which automatically sets the optimum standard output sensitivity--up to equivalent ISO of 3200, which is the highest automatic setting in its class--based on such data as the subject's brightness level and the lens focal length. Since this function allows the use of higher shutter speeds in poor lighting situations (such as indoor sports events and night scenes), it helps Photographers reduce camera shake and prevent blurred images.

Auto Picture Mode for effortless point-and-shoot SLR Photography
The K100D offers the exclusive Pentax Auto Picture Mode, which automatically and instantly selects one of the four Picture modes--including Portrait, Landscape and Macro--by calculating various Photographic factors to assure optimum results. Since this advanced shooting mode takes away all the concerns about aperture, shutter-speed, white-balance, saturation, contrast and sharpness settings, the Photographer can concentrate on image composition and shutter opportunity.

Large LCD monitor to facilitate image viewing and menu setting
The K100D incorporates a large 2.5-inch color LCD monitor on its back panel that offers a wide-view design that allows views from over 140 degrees vertically and horizontally, ensuring effortless image viewing even from a diagonal position. With a total of approximately 210,000 pixels, the monitor offers digital zooming of playback images up to 12 times for easy confirmation of the image's focusing status and details. The large monitor size allows for large letters, digits, and icons on the menu screens to facilitate menu confirmation and camera operations. In addition, the color scheme between the menu listings and the background is optimized for each menu screen to assure at-a-glance confirmation, even under varying shooting conditions.

True-to-life, rich-gradation images assured by 6.1 effective megapixels
The K100D features a large, high-performance 23.5mm x 15.7mm CCD as its image sensor, assuring the faithful reproduction of the desired Photographic intention in the resulting images--from images with beautiful out-of-focus backgrounds to those with edge-to-edge sharpness. Combining 6.1 effective megapixels with a high-performance imaging engine and advanced image-processing technologies, the K100D is designed to produce beautiful, true-to-life images that are rich in gradation. What's more, it offers a choice of two finishing touches of "Natural" or "Bright" to create a distinctive atmosphere.

Super-compact, ultra-lightweight body, with outstanding rigidity
While the K100D is designed to be compact and lightweight to enhance operability and portability, it also incorporates a newly developed stainless-steel chassis and a fiber-reinforced engineering plastic housing to reinforce its overall rigidity and durability.

Bright, clear viewfinder
The K100D features a lightweight penta-mirror viewfinder, which combines Pentax finder optics and a Natural-Bright-Matte II focusing screen to deliver bright, clear subject image with a 0.85x magnification and a 96 percent field of view.

Top shutter speed of 1/4000 second
The K100D offers a top shutter speed of 1/4000 second to freeze fast-moving subjects and capture decisive moments and features a flash synchronization speed of 1/180 second and a bulb setting (B) for extended exposures.

Continuous shooting at approximately 2.8 images per second
To trace the movement of an active subject or capture a sequence of the subject's expressions, the K100D offers a continuous shooting mode that allows the Photographer to capture multiple images (up to five images at "Best" image quality in JPEG format) at a maximum speed of approximately 2.8 images per second.

Upgraded standard software package
The K100D's standard software package consists of the Pentax Photo Laboratory 3 that features the reliable Silkypix image-processing engine (developed by Ichikawa Soft Laboratory) for RAW data processing, and the Pentax Photo Browser 3, which offers faster data processing speed and better operability than the previous version and can convert RAW images to the DNG format. DNG is a public, archival format for digital camera raw data.

Save-by-day Storage Capability on an SD memory card
Images may be stored in a standard format where all files are located in one folder, or the images can be stored in folders for each day of shooting automatically on an SD memory card.

Additional camera body features:
　

• 19 custom functions to personalize camera operations
• SD memory card compatibility

• PictBridge compatibility

Versatile wide-angle perspective
Mounted on a Pentax digital SLR camera body--including the new K100D--this lens offers an angle of view equivalent to a 32mm lens in the 35mm format. This versatile angle of view produces natural images with a moderate perspective and an expanded depth of field (or a wide in-focus area), making it ideal for many different types of subjects and occasions, including snapshots, landscape, travel photos, and architecture.

High-performance optics
This lens incorporates a hybrid aspherical lens in its eighth optical element to effectively compensate for a variety of aberrations, which cause adverse effects on overall image quality. In order to assure high-quality image reproduction over the entire focusing range, it also features a floating mechanism, which is designed to adjust the degree of aberration compensation in relation to the focusing distance.

Limited Lens-series quality for distinctive visual description and a premium appearance
The Pentax Limited Lens series is designed for ultimate image reproduction by combining a series of mechanical and numerical evaluations with human assessment of test shot samples. True to this tradition, this new lens not only assures excellent image quality, but also produces sharp, clear images with outstanding contrast even at the maximum aperture, because its optical design has been optimized for digital photography. In addition, its lens barrel, hood, and cap are all made of a high-grade aluminum material, shaped for perfect proportions and striking beauty.

SP coating to protect the lens against water and grease
The Pentax-original Super Protective (SP) coating is applied to the front surface of the lens. Through a vapor deposition process, the lens surface is coated with a special fluorine compound to repel dust, water, and grease, making it easy to wipe off fingerprints and cosmetics.

Digital SLR-exclusive design
This lens is exclusively designed for use with the Pentax digital SLR cameras, with an image circle perfectly proportioned to the CCD size (23.5mm x 15.7mm), and optics optimized for digital imaging characteristics. Combining high-quality image reproduction with an ultra-thin, super-lightweight design, it is a perfect partner to Pentax digital SLR cameras.

Other features
　

• Pentax-developed Quick-Shift Focus System for instant switching to manual-focus operation after the subject is captured in focus by the AF system
• Minimum focusing distance of 20 centimeters for close-up photography
• Dual filter attachment design: 43mm filters on the hood and 49mm filters on the lens (without use of the hood)
