The K-S2 camera body is not only designed to be compact and portable, but also dustproof and weather-resistant. One hundred seals have been applied to crucial parts of the body to prevent the intrusion of rain and dust into the interior, making the K-S2 a perfect choice for a wide range of outdoor activities, including mountain climbing, camping and sports events.

Variable-angle LCD monitor for easy image viewing
The K-S2 comes equipped with an Air Gapless LCD monitor, which has a special resin layer applied between the protective panel and the LCD screen to effectively cut down the reflection and dispersion of light and assure excellent visibility. This monitor also features a variable-angle design for the first time in a PENTAX digital SLR camera, allowing the user to set the monitor to the desired viewing angle and simplify high- and low-angle shootings.

High-precision autofocus system with SAFOX X module
The K-S2 features the state-of-the-art SAFOX X AF sensor module, which assures responsive, high-precision autofocus operation. With its 11 sensors including nine cross-type sensors in the middle, this AF system assures pinpoint focus on a subject at a minimum brightness level of as low as –3 EV.

High-resolution images produced by a CMOS image sensor with approximately 20.12 effective megapixels and a super-high sensitivity of ISO51200.

In-body shake reduction (SR) mechanism, and anti-aliasing (AA) filter simulator for effective moiré reduction

1. In-body SR mechanism
The K-S2 features a PENTAX-developed SR (Shake Reduction) mechanism to effectively minimize camera shake and assure sharp, blur-free images, even in camera-shake-prone conditions such as when using a telephoto lens, shooting low-light scenes with incident light only, or photographing sunset scenes.

2. Innovative AA (anti-aliasing) filter simulator**
By applying microscopic vibrations to the image sensor unit at the sub-pixel level during image exposure, the K-S2’s AA filter simulator provides the same level of moiré-reduction effect as an optical AA filter. Unlike an optical AA filter, which always creates the identical result, this innovative simulator lets you not only switch the AA filter effect on and off, but also adjust the level of the effect, so the user can effortlessly apply the desired effect to a particular scene or subject.
(3)Supportive shooting functions
The K-S2’s SR unit has a flexible design that tilts the image sensor unit in all direction, by shifting it horizontally (left/right) and vertically (up/down), and even rotating it. Taking advantage of this flexibility, the K-S2 provides a host of handy shooting functions, including ASTRO TRACER, which simplifies advanced astronomical photography in combination with the optional O-GPS1 GPS Unit.

Optical viewfinder with nearly 100-percent field of view
Despite its compact body, the K-S2 is equipped with a glass prism finder featuring the same optics and coatings as those used in higher-level models. With a magnification of approximately 0.95 times, it provides a broad, bright image field for easy focusing and framing.

High-speed shutter to capture fast-moving subjects in crisp focus
The K-S2 provides a top shutter speed of 1/6000 second to assure sharply focused images, even with fast-moving subjects. Coupled with its high-speed continuous shooting function with a top speed of approximately 5.5 images per second, it lets the photographer freeze once-in-a-lifetime shutter opportunities in beautifully focused images.

Wireless LAN compatibility for easy access to smartphones, for the first time in the PENTAX K series.
The K-S2 features wireless LAN (Wi-Fi) functions to provide better access to smartphones and tablet computers. It also provides NFC (Near Field Communication) functions for easy pairing with NFC-compatible smartphones and other communications devices, simply by bringing the K-S2 into proximity with a target device. Also by installing the newly developed, exclusive Image Sync application on a communications device, the user can effortlessly control the K-S2’s aperture, shutter-speed and ISO-sensitivity settings, release its shutter, check the live-view image, and even browse and upload recorded images onto SNS sites such as Facebook remotely.

RICOH-original image-processing technologies
The K-S2 features a Clarity Enhancement — a RICOH-developed imaging technology designed to capture the subject’s texture and unevenness more truthfully and produce a more true-to-life depiction of the subject based on the human visual characteristics. Also provided on the mode dial is a new A-HDR (Advanced HDR) position, which combines the Clarity Enhancement with the conventional HDR mode that composites a single, extra-wide-gradation image from three images taken at differing exposures. Thanks to this new mode, the user can capture more dramatic, painting-like HDR images with great ease.

Dual electronic dials
The K-S2 provides a pair of electronic dials: one on top of the grip, and another on the back panel. In the P (Program) mode shooting, for instance, the user can control the aperture and shutter-speed settings independently using these dials, allowing more intuitive camera operation without the need to remove the eye from the viewfinder.

Full HD movie recording
Equipped with a built-in stereo microphone, the K-S2 captures beautiful Full HD movie clips (1920 x 1080 pixels; 30/25/24 frame rate) in the H.264 recording format, along with natural, lively stereo sound. It also assures flawless, high-quality movies even with fast-moving subjects. It even provides advanced movie functions, such as a 4K Interval Movie mode that connects still images recorded at a certain interval to create a single movie file, and a Star Stream mode to fade in and out the traces of stars to recorded movies.

Other features

• 77-segment, multi-pattern metering system for high-precision light measurement
• DR (Dust Removal) mechanism for effective elimination of dust on the CMOS image sensor using ultrasonic vibration
• Self-timer functions usable in continuous shooting mode
