A minimum-sized, lens-interchangeable digital camera providing fashionable design and exceptional operability

RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of the PENTAX Q-S1 lens-interchangeable digital camera. In addition to its outstanding portability assured by the super-compact body, this new model offers solid basic specifications and a classic design with fine details. The combination of a well-conceived design and great operability makes the PENTAX Q-S1 an ideal everyday camera for photographers of all levels.

The PENTAX Q-S1 is the latest addition to the popular PENTAX Q series of compact-sized, lens-interchangeable digital cameras, which are developed to be more fashionable and user-friendly than digital SLRs. It comes equipped with a wide range of shooting features to make photography more enjoyable, including a 1/1.7-inch, back-illuminated CMOS image sensor to deliver high-quality images, high-sensitivity shooting to a top sensitivity of ISO 12800, and a reliable shake-reduction system using a state-of-the-art gyro sensor. It also provides a variety of creative tools, such as Bokeh Control to produce SLR-like bokeh effects with ease, and Smart Effect to add the desired filter effects with just a turn of a dial. Altogether, the PENTAX Q-S1 assists the photographer in creating more personalized, creative images more easily and efficiently.

Major Features

1. 1/1.7-inch image sensor to deliver high-quality images

Thanks to its 1/1.7-inch, back-illuminated CMOS image sensor, the Q-S1 delivers high-quality and high-resolution images. Coupled with the state-of-the-art high-speed engine name "Q ENGINE", it also minimizes annoying noises effectively at all ISO sensitivity levels to deliver rich-gradation, fine-texture images, even in high-sensitivity shooting using a top sensitivity of ISO 12800. It also offers outstanding autofocus accuracy during low-illumination shooting, since it assures pinpoint focus on the subject even at the faintest light level of EV 0.

2. Classic, high-grade design

The Q-S1 sports a classic design, with meticulous attention paid even to the texture of the finest details, making it a perfect everyday camera to carry around under all kinds of situations. Its Quick Dial and grip are made of high-grade aluminum for an exclusive look, and are symmetrically positioned for holding comfort and visual attractiveness. For the first time in the Q series, synthetic leather has been used for the front panel, to improve the texture and appearance.

3. Outstanding operability

Thanks to the incorporation of the Q ENGINE with an optimized algorithm, the Q-S1 assures quick, flawless response at all phases of shooting operation, including a short start-up time of approximately one second. The Quick Dial also lets the user assign as many as four favorite functions, including Smart Effect, aspect ratio, AF/MF switching, focus assist ON/OFF and ND filter ON/OFF, for instant mode switching during shooting.

4. Dependable SR mechanism

The Q-S1's advanced SR (Shake Reduction) mechanism features a state-of-the-art gyro sensor to effectively compensate for annoying camera shake. It produces sharp, blur-free images even under shooting conditions prone to camera shake, such as when using a telephoto lens, shooting in the dark without flash illumination, or capturing landscapes in the twilight.

5. Full HD movie recording, even during high-sensitivity shooting

The Q-S1 captures beautiful Full HD movie clips (1920 x 1080 pixels, at 30 frames per second, in the H.264 recording format) with minimal noise. It also provides an interval HD movie recording function to add more creativity to visual expression. The user can also take advantage of advanced image-processing tools like the Smart Effect modes* and an array of in-body movie editing tools. The Continuous AF (AF-C) mode** has been newly added to these creative options, allowing the user to capture a moving subject in sharp focus during movie recording.

* The frame rate may vary when a selected Smart Effect mode requires nonstandard image processing.
** This mode is not compatible with the UNIQUE LENS-series lenses and the 06 TELEPHOTO ZOOM lens.

6. Large, high-resolution 3.0-inch LCD monitor

The Q-S1 features a high-resolution 3.0-inch 3:2-proportion LCD monitor with approximately 460,000 dots. This monitor is treated with AR (Anti-Reflection) coating to produce sharp, bright images even under bright sunshine by effectively minimizing glare and reflection on the screen. Since its wide-view design makes it possible to view the image from 170 degrees horizontally and vertically, the user has a clear view of the on-screen image even when facing the monitor from an angle.

7. An array of image-processing tools to create personalized images

(1) Custom Image function to add distinctive finishing touches
The Custom Image function adds a distinctive finishing touch to an image, faithfully expressing the photographer's creative intention or reproducing the ambience of a specific scene. The user has a choice of 11 Custom Image modes, including Bleach Bypass, which produces a dramatic, movie-like finish.

(2) Digital filter function to apply artistic visual effects
The digital filter function lets the photographer apply a variety of visual effects without requiring a computer. Of 17 total options, 11 filters including Toy Camera, Invert Color and Posterization can be applied even during the shooting of still images and movie clips, while the remaining six can be applied only during image editing. The user can even apply multiple filters to a single image to produce more inventive visual effects.

(3) Smart Effect function for simple dial control of finishing touches
Using the Quick Dial positioned on the camera's front panel, the user can quickly and effortlessly add a desired finishing touch to an image, while previewing the applied effect on the LCD monitor. From nine Smart Effect modes -- including Antique for an nostalgic atmosphere and Fade Color for a chic, faded-color finish -- the user can assign four favorite modes to the dial in advance.

8. Effortless Bokeh Control

The Q-S1's unique Bokeh Control function allows the user to make the subject stand out by automatically assessing the relative distance between the in-focus subject and obtrusive objects in the field of view. Since this function simplifies the advanced, SLR-caliber technique of intentional defocusing, even a first-time digital camera user can effortlessly capture high-quality images with beautifully defocused foregrounds and backgrounds.

9. Simple, user-friendly Auto Picture and Scene modes

The Q-S1 features the PENTAX-original Auto Picture mode, which automatically selects the most appropriate shooting mode from an range of options including Portrait, Landscape and Macro for a given scene or subject. Since the camera optimizes all affecting parameters, such as shutter speed, aperture, white balance, saturation, contrast and sharpness, the user can concentrate on the image composition and shutter opportunity. The Q-S1 also provides 21 Scene modes including Night Scene Portrait, Pet and Backlight Silhouette, allowing even an entry-level digital photographer to choose the best exposure settings for a complicated scene or subject with the simple choice of an icon on the LCD monitor.

10. Digital SLR-caliber exposure system

The Q-S1's comprehensive exposure system assures all the advantages and flexibility of a lens-interchangeable digital camera system. In addition to the all-purpose Programmed AE (P) mode, which automatically selects an optimum combination of aperture and shutter speed, it also provides the Aperture-Priority AE (Av) and Shutter-Priority AE (Tv) modes for manual setting of a desired aperture or shutter speed, as well as Metered Manual (M) mode for complete user control over exposure settings.

11. DRII mechanism for effective dust removal

The Q-S1's DRII (Dust Removal II) mechanism effectively prevents annoying dust spots from spoiling captured images, even after the user changes lenses out in the open. Like the PENTAX K-3 and 645Z digital SLR cameras, it employs a highly efficient supersonic vibration mechanism, which vibrates the image sensor at high speed to shake dust off its surface.

12. Other features

  • ・Compatibility with Eye-Fi wireless LAN SD memory cards
  • ・High-speed continuous shooting of up to five images per second
  • ・HDR mode to composite three images of varying exposures into one photo with extra-wide dynamic range
  • ・CTE white-balance control mode to emphasize the predominant color of a particular scene, such as the sunset
