The K-S1 features a PENTAX-original SR (Shake Reduction) mechanism that can be used with any compatible PENTAX interchangeable lens. The SR stabilization system is built right into the body, and is compatible with any of the 27 million PENTAX lenses ever produced. Thanks to the addition of an SR-dedicated servo controller and an increase in the magnetic force driving the SR unit, this mechanism assures more stable, effective camera-shake compensation than ever before.
Enjoy the world’s first selectable anti-aliasing filter applies microscopic vibrations to the image sensor unit at the subpixel level during image exposure, generating the same level of moiré-reduction effect as an optical anti-aliasing filter. Unlike an optical anti-aliasing filter that always creates the identical result, this innovative simulator allows the user not only to switch the anti-aliasing filter effect on and off, but also to adjust the level of the effect. This allows the user to set the ideal effect for a particular scene or subject.
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-S1’s AA filter simulator provides the same level of moiré-reduction effect as an optical AA filter.
Pentax K-S1 supports Pentax O-GPS1 GPS Module for GPS and Astrotracing capability. It will add latitude, longitude, altitude, UTC capture time and direction as image metadata. This data can be used to place images in mapping software such as Google Earth or as a means of file organization and retrieval. It also makes astronomical photography much simpler, as it requires only a tripod and eliminates the need for an additional accessory such as an equatorial telescope.
By setting the Mode dial to the EFFECT position, the user can apply the desired visual effect to an image while previewing the outcome on the LCD monitor. It provides a choice of 10 distinctive effects, including three new options: “Fresh” with a crystal-clean finishing touch; “Fade Color” for an elegant finish with subdued colors; and “Infrared” for a black-and-white finish like that of an infrared photo. The K-S1 also provides 21 digital filters (nine of them applicable during shooting), including a new “Color Replacement” filter.
In addition to the effective compensation for distortion, chromatic aberration and peripheral brightness, the K-S1 also provides compensation function for diffraction, which deteriorates image resolution when a small aperture is used.
The K-S1 captures beautiful Full HD movie clips (1920 x 1080 pixels; 30/25/24 frame rate) in the H.264 recording format, which assures flawless, high-quality movies even with fast-moving subjects. It is also equipped with a built-in stereo microphone for recording natural sound during Full HD movie recording.
Pentax K-S1 comes with built-in Live View capability which allows user to perform composition directly through the LCD Screen. It also feature Focus Peaking capability in Live View Mode. This feature allows user to perform Manual Focusing at ease. The camera will highlight on the LCD screen the area or subject in focus making composition an enjoyment.
Compatible with Eye-Fi wireless LAN memory cards for easy file transfer between images, highly accurate 77 segment metering system for perfectly exposed images even in difficult lighting. and DR (Dust Removal) mechanism for effective elimination of dust on the image sensor using ultrasonic vibration.
Pentax K-S1 is designed to be fully compatible to all Pentax Legacy lenses. You can now enjoy Pentax lenses without having to be concern of its compatibility issue.
Pentax K-S1 supports Pentax O-FC1 FLUCARD Pro allowing user to wirelessly control the camera from Smartphone, tablet or laptop. With installation of the optional, dedicated 16 GB FLU CARD for PENTAX in the K-3, the photographer can remotely change settings such as aperture, shutter speed and ISO, shift the AF focus point, release the camera shutter, check Liveview image, and browse and nd download the images recorded on the card using a smartphone and PC.
