Pentax's Optio S4 digital camera. Courtesy of Pentax, with modifications by Michael R. Tomkins. Pentax announces Optio S successor (UPDATED)
By
(Wednesday, September 3, 2003 - 11:00 EDT)

In the second of three announcements today from Pentax Corp., the company updates its Pentax Optio S - the model that first introduced an unusual lens whose internal elements actually "unstack" as the lens retracts, arranging themselves side by side within the camera body.

Announced in January, the Optio S was quickly followed by a similar model from partner company Casio - so when Casio overhauled their camera last week, we're sure astute readers immediately expected an announcement would be forthcoming from Pentax as well. The new Optio S4 digital camera retains the unusual lens design of the Optio S - which we were pleasantly surprised by when we reviewed that model earlier this year.As you'd expect, the compromise of the lens design does affect image quality a little - but nowhere near as much as we'd expected.

So - what's new in the Optio S4? Externally, the camera looks almost identical - size and weight are the same, and Pentax will still be able to impress at trade shows by fitting the camera inside an Altoids tin... Resolution has been increased from 3.2 to 4.0 megapixels (effective), for a maximum image size of 2304 x 1728 pixels. The digital zoom is now a 4x instead of 2x zoom, although this may be of little significance to users who understand that they can generally do as good or better a job interpolating images on their computer.

Longer exposures are no longer limited to 1 second - the Optio S4 offers shutter speeds from 1/2000 to 4 seconds. An extra digital filter simulating a soft-focus filter has been added. Movies can now be twice as long as the previous model, with a limit of 60 seconds per movie clip. The movies are also slightly faster, at 15fps vs. 12fps on the older camera.

The Pentax Optio S4 will ship in October, with pricing not yet announced. Specifications, product photos and the Pentax press release follow below:

Original Source Press Release:

NOT BIGGER, JUST BETTER: TINY, SECOND GENERATION PENTAX OPTIO OFFERS FOUR MEGAPIXELS

ENGLEWOOD, Colorado (September 3, 2003)…The innovative manufacturer that introduced a popular digital camera tucked inside a breath mint tin, has introduced a second generation. PENTAX U.S.A., Inc. announced the launch of the Optio S4. Sporting the tiny dimensions and light weight of its predecessor, the Optio S4 boasts a hefty 4.23 effective megapixels, a 3X zoom lens, and a variety of features including a large, easy-to-use manual control playback button.

PENTAX U.S.A., Inc. will preview the tiny but powerful digital camera at the Digital Focus media event on Monday, September 15 at the Metropolitan Pavilion in New York City during the PC EXPO trade show.

How does PENTAX continue to load so much into such a small space? The Optio S4 features an innovative Sliding Lens system that allows the camera’s powerful 3X zoom lens to move up and away so the retracted lens is completely flush with the camera body. This novel system protects the lens and helps reduce the size.

Despite the size, the Optio S4 boasts all the features found on other Optio digital cameras: a movie mode with sound playback, a voice recording memo for attaching 30 second memos to select images, a well-placed 1.6 monitor, and approximately 11MB of built-in memory. All these features and more are made even more accessible through a larger, well-placed manual control playback button on the Optio S4.

The Optio S4 includes an ACDSee™ software package designed exclusively for PENTAX Optio digital cameras that includes ACDSee™ 5.0. Valued at more than $150, ACDSee™ digital camera software makes it easy to retrieve, view, manage, print, enhance and share your digital photos. The Optio S4 will ship with the software in October in plenty of time for the Holiday 2003 buying season.

PENTAX U.S.A., Inc. is an innovative leader in the production of digital and film cameras, binoculars, lenses, mobile printers, scanners and internet cameras. For more than 80 years, PENTAX technology has developed durable, reliable products that meet the needs of consumers and businesses. PENTAX U.S.A., INC. is a wholly owned subsidiary of PENTAX CORPORATION.

World time function
The Optio S4 can display the time for 62 different cities around the world. It can also record the time and date for each shot taken, making the sorting of shots so much easier upon your return.

Alarm function
An alarm function makes the Optio S4 handier to have around. The camera may be set to display the image of your choice when the alarm sounds, showing something related to your schedule, for example, or simply displaying a friendly face.

DPOF compatibility
The user can claim a further degree of control over printouts thanks to DPOF compatibility, which lets you make use of the date function and decide the number of copies*.
* Some printers may not support the above function. Please consult the supplier of your printer for more information.

Exif Print and PRINT Image Matching compatibility
When used with Exif Print (Exif 2.2) and PRINT Image Matching-compatible printers, the Optio S4 can produce prints of an even higher quality.

A resize function allows the data size of recorded shots to be reduced. This frees up space to capture more shots without having to delete ones already taken, and resized data can be stored as new files or used to overwrite the previous images.

Trimming
The useful Trimming function allows images to be cropped and parts to be selected for storage on their own as individual files.

Voice memo function
Up to 30 seconds of sound can be attached to recorded images, allowing situations to be captured in a much more memorable manner.
