Colour Choices:

20-megapixel AA-Filterless CMOS sensor

A high performance 20 megapixel AA-Filterless APS-C CMOS image sensor strikes the perfect balance between resolution and image quality.

Prime MII Image Processing Engine

The PRIME MII image processing engine is optimized for HD video capture, smooth live view, low chromatic noise, and low energy consumption.


The SAFOX X AF module ensures fast and accurate autofocusing, even in challenging situations such as extremely low light environments. Equipped with 11 focusing points (9 cross-sensor points), the Center point also works with F2.8 luminance flux. Expanded area AF allows for accurate focusing, even on moving subjects.

Built-in WiFi

With the built-in WiFi and NFC module, users can wirelessly control camera operation, transfer images, and view images, making image transferring and sharing easy and seamless. A dedicated app (Image Sync) is available for Android and iOS devices. Image Sync app brings improved ease of use to wireless tethering.

Clarity Enhancement Feature and Advanced HDR Mode

Newly adopted clarity enhancement option adds more realistic texture impression to images by enhancing the spatial frequencies to match with human visual characteristics. Enjoy outstanding clarity even on screen-fit view on a variety of display monitors from a tablet PC to 4K high-resolution displays. Choose the Advanced HDR Mode (A-HDR) on the mode dial and “Clarity Enhancment” is automatically applied to images.

In-body Shake Reduction (SR)

The In-body shake reduction (SR) mechanism effectively compensates for camera shake regardless of the lens type mounted.

Smallest Weather-Resistant DSLR

The combination of K-S2’s world’s smallest weather resistant DSLR body and ultra thin zoom lens allows for compact size with exceptional DSLR power.

Fully Weather-sealed

With 100 weather seals throughout the entire body, your K-S2 ensures worry-free use in any weather condition or outdoor setting, be it rain or sand.

Retractable Standard Zoom Lens

Vari-angle LCD

The K-S2 is the first PENTAX DSLR with a Vari-angle LCD. It extends the freedom of shooting position from high angle to ground level view. The 3.0 inch, 921K dot Air Gapless LCD construction ensures good visibility of displayed image even outdoors. The electronic level indicator assists precise composition.

Pentaprism Viewfinder for 100% Field of View

Despite its compact size, the K-S2 features a glass prism finder with 100% field of view and approximately 0.95-times magnification (with a 50mm F1.4 lens at infinity) to cover the entire field of view for easy focusing and framing.

2 E-Dial Operations

2 Electronic dials enable simultaneous adjustment of aperture and shutter speed settings.

User Customization

Customization options to fit all users requirements. Various settings can be registered on User1, User2.

Self-Shot Assist

The K-S2’s vari-angle LCD monitor and 2nd shutter release button help you to capture your best ’selfie’ in just 3 steps.

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

The K-S2 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. Versatile drive settings include: Multi-exposure, Interval shooting and Interval composite.

High-sensitivity shooting at ISO 51200

High sensitivity shooting up to ISO 51200 improves noise performance throughout, even in low lighting.

Full HD movie recording with stereo audio

The K-S2 captures beautiful Full HD movie clips at 30fps, 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, as well as an external microphone connector. Capture time lapse movies in HD with the ‘Star Stream’ functionality, allowing you to record series of still images, such as stars, and save them as an AVI movie.
