(Wednesday, August 25, 2004 - 09:35 EDT)

Casio Japan and Casio USA have today simultaneously announced the first digital camera featuring a lens made from a transparent polycrystalline ceramic material.

Thanks to the use of Lumicera, a material developed by Murata Manufacturing Co. Ltd. that offers a higher refractive index and better strength than optical glass, Casio says it's EXILIM EX-S100 is the smallest digital camera with a 2.8x optical zoom. With dimensions of just 88 x 57 x 17 millimeters, the EX-S100 is certainly small - some 10mm shorter and 3mm smaller than Konica Minolta's DiMAGE Xg, and 15mm less wide than Sony's Cyber-shot DSC-T11. The S100 features a 1/3.2"-type 3.2 megapixel (effective) RGBG image sensor for a maximum image size of 2048 x 1536 pixels, along with a 2.0" LCD display, built-in four-mode flash, 9.3MB of built-in flash memory, SD / MMC card storage, and power from a proprietary Lithium Ion rechargeable battery. There are also some less common features for such a compact camera - an RGB histogram, movie mode with audio, voice recorder mode, and user-adjustable sharpness, saturation, contrast and flash strength. A particularly unusual feature is the new Business Shot mode, which is intended for capturing images of whiteboards and the like from an angle - the camera will automatically correct for trapezoidal distortion in the image, restoring the correct rectangular projection.

The Casio EXILIM EX-S100 digital camera will be available in October 2004 at a price of $399.99. Full specifications, product photos and the official press release follow below:

Original Source Press Release:


World's First Ceramic Lens Debuts In Stylish and Elegant “EXILIM CARD” EX-S100 Featuring 3.2 MP CCD and 2.8X Optical Zoom

DOVER, NJ, August 25, 2004 – Casio, Inc ., in conjunction with its parent company, Casio Computer Co., Ltd., Tokyo, Japan, announces the release of the world's smallest* digital camera with an optical zoom (2.8X) , the EXILIM CARD EX-S100 . The camera and its lens owe their exceptionally compact packaging to another world's first – the application of ceramic lens technology providing a great advance in optical quality with even greater strength than glass.

*As of August 25, 2004

“In 2002, Casio launched the first EXILIM digital camera, an ultra- thin business card-sized model with superior portability and highly responsive operation. Casio's highly-portable camera – which enabled photography for any occasion, anytime, anywhere – had a huge impact on the digital camera market overnight, helping the ultra-slim genre become a major segment of its own.” said John Clough, president of Casio, Inc. “ Since that first EXILIM, Casio has continued to create even thinner cameras with more rapid responsiveness and superior performance, creating an EXILIM lineup that has expanded to become a trend-setting force in the marketplace. The new EXILIM CARD EX-S100 is the latest breakthrough model in the line.”

The new EXILIM CARD EX-S100 was developed to be the flagship model of the series, and as such, embodies all the brand concepts. Key features of the EX-S100 include use of the world's first transparent ceramic lens in an ultra-slim 2.8X optical zoom lens unit, and Casio's proprietary EXILIM Engine, an ultra-compact image processing LSI module that enables the camera to achieve high-image quality, high-speed operation and low power consumption – all within an extremely slim and compact body package . As a result, the EX-S100 is the world's smallest optical zoom-equipped digital camera, with a volume of just 79 cc and very compact measurements of 3.46” x 2.24”. Moreover, it is only .66” thick, and just .56” at the thinnest point.

The EX-S100 features a stainless steel body, a hallmark of the EXILIM CARD series, which has been polished to a brilliant shine through a special process. It is created entirely of metal, right down to the screws, for a true feeling of high quality. The front of the camera features a stylish theme of circular patterns that highlight the shape of the lens, while the back of the unit features a more square look that matches the impressively large 2.0-inch LCD screen. In keeping with the distinctive form of the other models in the EXILIM CARD series , the lens area itself protrudes slightly from the body of the camera.

With a 3.2 Mega pixel CCD for superior high-resolution photo imaging, a unique quick-response design, and a Best Shot function that makes it easier to capture desired scenes , CASIO has again proven that it is the leader in ultra-compact camera s that offer astonishingly advanced performance.
