The essence of high-quality digital photography

(focal length 3.8mm, equivalent in 35mm format: 17mm).Shutter speed: 1/30 sec., F3.7, 0.0EV, ISO100,WB: Tungsten

Exceptional image quality with true-to-life description

The key components needed for superior image quality are the image sensor, imaging engine and lens. By optimizing these three components, the PENTAX Q-S1 assures the beautiful image rendition demanded from lens-interchangeable digital cameras.


Featuring the exclusive Q ENGINE as its imaging engine, the PENTAX Q-S1 not only assures extra-fine image description and efficient noise processing, but also provides a host of shooting and image-editing functions. This imaging engine is also the key to responsive, high-speed camera operation.

【1/1.7-inch back-illuminated CMOS image sensor】

The PENTAX Q-1 features a 1/1.7-inch back-illuminated CMOS image sensor with a wide dynamic range at high-sensitivity settings. With approximately 12.4 effective megapixels, it produces beautiful, high-resolution images with rich gradation and minimal noise.

【Q-mount lenses】

The PENTAX-original Q-mount lens system optimizes optical performance while minimizing the camera’s bulk. With a variety of interchangeable lenses to choose from, you can react swiftly and flexibly to all types of subjects to faithfully express your creative intentions.

For effective reduction of camera shake with all lenses
In-body SR (Shake Reduction)

The PENTAX Q-S1 features a sensor-shift-type SR system, which effectively suppresses blurring even when shooting low-light scenes or distant subjects using a telephoto lens.* This system even works with lenses other than Q-mount lenses, simply by inputting the focal length.

* The degree of compensation may vary depending on the lens used and/or shooting conditions.

To prevent blurred images in low-light shooting
Top sensitivity of ISO 12800

The PENTAX Q-S1 boasts a maximum sensitivity of ISO 12800. It assures true-to-life images with minimal noise, even during high-sensitivity shooting. In low-light shooting, it minimizes blurring caused by camera shake and subject movement, without the need to reduce the shutter speed. You can handhold the camera in a wider range of situations than ever before.

To keep the image sensor spotless and free of dust
DR II (Dust Removal II)

The DR II mechanism efficiently removes dust adhering to the CMOS image sensor using ultrasonic vibration. You can activate it manually whenever you feel the need, or select automatic operations every time the camera’s power is switched on or off.
