Compact Design. Bright Inspiration.

Experience photography in a new light with the PENTAX K-S1. Whether you’re new to photography or a skilled enthusiast, the K-S1 offers you the ability to take your imaging to the next level. The K-S1 incorporates new elements that optimize digital innovations, such as a compact, modern design and an inventive interface system. The addition of LED lights adds brilliance to its exterior, while enhancing functionality. The K-S1 also provides other outstanding features, rivaling those of high-end models, including: the PENTAX-developed anti-aliasing filter simulator (first incorporated on the PENTAX K-3), an optical viewfinder with a glass pentaprism to provide approximately 100% field of view, and an in-body shake reduction mechanism. If you’re looking to upgrade your mobile photography, the PENTAX K-S1 is sure to smooth the transition with compactness, style and outstanding performance.

 
  • High-speed shutter to capture fast-moving subjects in crisp focus

    The K-S1 provides a top shutter speed of 1/6000 second to capture the decisive moment. Coupled with its high-speed continuous shooting function (with a top speed of 5.4 images per second), it lets the photographer freeze once-in-a-lifetime shutter opportunities.

  • A selection of image-processing tools for creative, personalized expressions

    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.

  • Connected device functions**

    The optional FLUCARD FOR PENTAX 16GB memory card can release the K-S1’s shutter, provide a live-view image, and browse and download the images recorded on the card using a smartphone or other wireless and web browser enabled device. ** These functions support smartphones operating iOS6 or later and Android 4.2 or later.

  • Full HD movie recording with stereo audio

    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.

  • High-precision AF with SAFOX IXi+ AF sensor module

    The K-S1 features the SAFOX IXi+ AF sensor module, which assures responsive, high-precision autofocus operation with 11 sensors, including nine cross-type sensors. It also provides a spot beam to assist AF operation in poorly lit locations. Its select-area expansion function ensures that the sensor module keeps tracking a moving subject, even when the subject moves out of a pre-assigned auto-tracking area, by assessing the distance data collected by neighboring focus sensors. The AF hold function maintains the in-focus position, even when the AF system loses track of the subject after once capturing it in focus. These functions combine to improve the camera's accuracy in the detection of moving subjects when its focus mode is set to AUTO, and upgrade its auto-tracking performance of these subjects when using a telephoto lens.

  • Dependable lens aberration compensation system

    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.

  • 3.0-inch, high-resolution LCD monitor, and newly designed, easy-to-use interface

    The K-S1 features a high-resolution, wide-view LCD monitor with approximately 921,000 dots. It also provides a status screen employing the newly-designed GUI (Graphical User Interface), which allows the user to confirm functions and settings assigned to the four-way controller and the OK button at a glance. The RICOH RT font has been used for on-screen menus to improve readability.
