The Pentax K-S1 combines DSLR ergonomics and image quality with an intuitive shooting experience. Packed with innovative features, it is capable of satisfying your creative requirements well into your photographic journey.
Razor sharp images and true-to-life colour reproduction are delivered via a 20 megapixel CMOS sensor. Its design eliminates the AA (anti-aliasing) filter to ensure maximum imaging power for stunning detail-rich results.
A high performance PRIME MII imaging engine complements the sensor specifications, offering a maximum ISO 51200 for superb shooting versatility and low-noise images, even when shooting in difficult lighting scenarios. Full High Definition video recording with stereo sound recording is also possible and supports a variety of frame rates to suit your requirements.
An aberration compensation system is also supported by the image processor. The system optimises image quality by automatically removing aberration and diffraction based on the characteristics of the lens attached to the camera, resulting in better contrast and picture detail across the entire frame.
Great for shooting fast moving action, the KS1 is equipped with a blistering 1/6000th shutter speed and 5.4fps continuous shooting to ensure you can freeze life’s most fleeting moments with confidence and ultra-sharp clarity.
In-camera shake reduction (SR) adds versatility to all shooting scenarios, effectively minimising blur and producing sharper images when shooting with long lenses and in low-light, slow shutter speed scenarios.
The proven SAFOX IXi+ autofocusing sensor delivers precise, intelligent auto focus performance. It consists of 9 cross-type sensors for consistently fast focusing and provides flexible framing and composition options. The incorporation of sophisticated tracking algorithms allows you to use the motion tracking function to maintain critical focus of moving subjects, especially useful when shooting with telephoto lenses.
When inspiration strikes, the Effect Mode allows you to choose one of 10 distinctive effects to give your photos a unique flair. The effects can be previewed in real-time, allowing you to see the end result before you actually press the shutter. Effects include ‘fresh’, fade colour and infrared. An additional 21 digital filters can be applied after the shot has been taken and includes the popular colour replacement filter.
The K-S1 features an intuitive LED illuminated interface for easy visual reference of your camera settings. For example, the design uses a green LED surrounding the power switch to indicate the camera is in photo mode, while a red light indicates the camera is set to video mode. LED lights embedded into the grip light up to indicate how many faces it has detected in face detection mode, and doubles as a countdown timer when shooting with the self-timer mode.
Composition is straightforward via the high-quality 100% field-of-view optical viewfinder or the large 3-inch 921k-dot wide-view LCD monitor, ensuring precise framing in a broad range of lighting conditions. A newly designed interface combined with a four-way controller ensures intuitive menu navigation efficient photo and video playback.
The Pentax K-S1 is compatible with Eye-Fi* and FLU*wireless SD cards to ensure you’re equipped to instantly share your high-quality images with your friends, family and favourite social networks.
