Pentax's Optio S1 digital camera in black, chrome, and green finishes. Photo provided by Pentax Imaging Co. Pentax S1: Stylish Optio ultracompact announced
(Wednesday, March 2, 2011 - 17:00 EST)

Pentax Imaging Co. has today announced the Optio S1, its latest style-conscious ultracompact digital camera.

Available in three choices of body colors with laser-etched front panel marking -- chrome with black trim, black with red trim, or green with silver trim -- the aluminum-bodied Pentax S1 definitely aims to make a fashion statement, but that's not its only focus. The Pentax Optio S1 is also the company's first compact camera model to include an in-camera high dynamic range imaging function.

The 14 megapixel Pentax S1 also includes a 5x optical zoom lens, 720p high-def movie capture capability, sensor shift image stabilization, a 2.7-inch LCD display, and a five mode flash strobe. Power comes from a proprietary lithium ion battery pack that charges inside the S1's body, while images and movies are stored on Secure Digital cards, inclusive of the latest SDHC and SDXC types.

The Pentax Optio S1 digital camera ships later this month, with pricing set at around US$200. More details can be found in our Pentax S1 preview.

Three Stylish Colors
The PENTAX Optio S1 aluminum alloy housing is available in three high-quality finishes including a mirror-finish Chrome, or a high gloss Black or Green. Each model features a color coordinated lens barrel and translucent control buttons, as well as laser-engraved logos and feature descriptions on the front panel. The meticulous design detail of the Optio S1 makes it a digital camera that doubles as a fashion accessory.

Versatile 5X optical zoom lens with 28mm wide-angle coverage
The ultra-compact Optio S1 features an 5X optical zoom lens covering focal lengths from 5mm to 25mm (equivalent in the 35mm format to approximately 28mm wide angle to 140mm telephoto) that may be used for a wide variety of subjects and scenes including landscapes, architecture, group portraits in confined spaces, and tightly cropped snapshots taken from a distance. An Intelligent Zoom function allows even tighter zooming in on the subject, extending the digital zoom range up to 33.5X with no loss of image fidelity.

Exceptional image quality
With exceptional image resolution of 14 effective megapixels and an advanced imaging engine with a high-performance PENTAX zoom lens and a mechanical Shake Reduction (SR) system, the Optio S1 delivers brilliant, high-quality images with well-defined details even when enlarged to poster size.

Triple Shake Reduction (SR) image stabilization technology to prevent image blur
Sensor-shift SR
The Optio S1 offers and advanced sensor-shift SR mechanism for sharp, blur-free images even when shooting telephoto shots, sunsets or indoor scenes in incident light. The camera compensates for camera shake up to approximately three shutter steps.

High-Sensitivity Digital SR*
The Optio S1 automatically raises the sensitivity as high as ISO 6400 for higher shutter speeds to minimize the adverse effects of camera shake and subject movement when shooting still images in low-light conditions.
* When the High-Sensitivity anti-shake mode is selected, the recorded size is fixed to 5M (2592 x 1944 pixels).

Movie SR*
During movie recording, the Optio S1 can prevent blurry images and annoying camera shake by using Movie Shake Reduction.
* When the Movie SR mode is selected, the angle of view becomes narrower than normal shooting.

High-quality, widescreen HD movie recording with dedicated REC button
The Optio S1 captures detailed movie clips at 16:9 high-definition TV resolution (1280 x 720 pixels)* at a frame rate of approximately 30 frames per second. A new, dedicated Movie REC button positioned on the back panel initiates movie recording from any shooting mode without delay.
* When the Optio S1’s AV output terminal is used, movie clips are output at standard definition. If the user wishes to play back movie clips in high definition (1280 x 720 pixels), the data must be transferred to a personal computer for playback.

Advanced, user-friendly Auto Picture mode for hands-off selection of the best shooting mode
The Optio S1 features the PENTAX-original Auto Picture mode that automatically selects the most appropriate shooting mode for a given subject or scene by accurately and instantly accessing all photographic conditions affecting the subject or scene. This set-it-and-forget-it mode detects 14 different subjects and scene types including people, landscape, blue sky, sunset, and more. The mode instantly optimizes all camera settings such as sensitivity and shutter speed for the quality images for the type of subject and scene identified.

Upgraded face detection for greater convenience
A new-generation Face Detection AF & AE function instantly and accurately detects the subject’s face in the image field and a Natural Skin mode reproduces natural, healthy skin texture.

Creative digital filters and tools
The Optio S1 offers nine digital filters, including Toy Camera and Retro, to add various creative visual effects to recorded images without a computer. A new Miniature filter converts any scene into an image full of miniatures, and an HDR filter (first ever on a PENTAX compact) produces images with outstanding exposure detail in wide exposure situations.

Additional features

  • Wireless remote shooting using an optional PENTAX infrared remote control

  • Large 2.7-inch color LCD monitor with approximately 230,000 dots for easy viewing of images and menus

  • In body recharge system for simple and convenient, cellphone-like battery recharging
