Casio Exilim EX-Z55

DOVER, NJ, August 25, 2004 – Casio, Inc., in conjunction with its parent company, Casio Computer Co., Ltd., Tokyo, Japan, announces the release of the 5-megapixel EX-Z55 and EX-Z50, two new models in the EXILIM ZOOM range of digital cameras with long battery operation and large LCD viewing screens.

Earlier this year, CASIO introduced the 4-megapixel EXILIM ZOOM EX-Z40, a thin-body digital camera with a large 2.0-inch TFT LCD screen. This model offered high picture quality, high-speed response and energy saving circuitry in a compact unit. Thanks to the incorporation of CASIO’s proprietary compact image processing module, the EXILIM Engine, the model also offered superior portability and exceptional performance, providing 2.5 times longer battery life (comparison between EX-Z4U and EX-Z40), and representing a significant improvement over what remains a common drawback with conventional digital cameras. This attention to the needs of consumers in terms of features and usability ensured the EX-Z40’s extraordinary popularity.

"Our new EXILIM ZOOM models, the EX-Z50 and the EX-Z55, both incorporate Casio’s heralded EXILIM Engine, the compact image processing module with a 3 layer stack LSI that enables high picture quality and speedy response using a 1.8V low-power system," said John Clough, President of Casio, Inc. "They now feature circuitry enabling even lower power consumption providing users with a much longer battery life, allowing them to take up to 400 pictures on a single charge. This means that these cameras are perfect for work or travel applications where it may not be possible to regularly charge the battery." In addition, continued Clough, "both the EX-Z50 and the EX-Z55 introduce the ‘Business Shot’ function. This enables users to take a trapezoidal distorted picture of a projector, white board, document or business card from a side angle and correct it to a rectangle automatically. This empowers the professional consumer with enormous convenience and flexibility."

Casio Exilim EX-Z55

The EX-Z55 is equipped with a high resolution 5-megapixel CCD, a 3X optical zoom lens and a larger 2.5-inch LCD screen incorporating an optical viewfinder. With its compact and stylish design, the EX-Z55 can take approximately 400 pictures (based on CIPA* standards) on a single charge. The EX-Z50 has a 2 inch LCD screen and can take approximately 390 pictures. Both models offer extended battery life, making them ideal for use during long vacations and business travel, in fact any occasion requiring the amazing stamina that these cameras now offer.

Like all models in the EXILIM series, they offer superior portability and excellent picture quality, along with extremely high-speed operation for quick response in a variety of shooting situations. One example is the Best Shot function that allows the user to select settings automatically by choosing from sample scenes. In addition, several new functions have been incorporated to assure a higher level of performance, such as the "Auto Macro" function which automatically switches between macro mode and AF mode; "Flash Assist" which operates during flash photography to compensate for brightness levels in darker areas not reached by the flash; "Icon Help" which uses an on-screen display to guide the user during the switching of settings; and the "Business Shot" function which provides automatic correction for photos taken at an angle.
