The EXILIM EX-Z850 Zoom offers 8.0 megapixels of resolution, a 3x optical zoom lens and a large 2.5-inch Super Bright LCD, all housed in a slim, durable, and pocket-sized package. The Z850's battery now has an even longer life, supporting an amazing 440 shots per charge. The camera also features Casio's Anti Shake DSP which, along with the Auto Macro and Quick Shutter functions, considerably reduces the incidence of blurred images due to moving subjects or shaking hands.

The large 2.5-inch Super Bright LCD is approximately three times brighter than the previous EX-Z500 model, producing an impressive luminance of 1200 candelas per square meter. This significant advancement makes the LCD easier to see, especially when viewed in the sunny outdoors. In auto mode, the LCD automatically adjusts to the brightness of the surrounding environment.

New and exclusive to the Casio EXILIM line of digital cameras in the U.S., is the eBay Best Shot mode. The eBay Best Shot takes photos at a size that is image optimized for display on eBay, allowing picture takers to more quickly and easily create photos for selling items on eBay. eBay Best Shot mode also includes Auto Macro, an ideal setting for capturing images of small items such as jewelry, tags, etc., thus automatically adjusting the focus from acquiring fine details in close up shots to capturing large items from a distance. eBay Best Shot mode allows users to capture optimized images at an ideal size for eBay.

Other EX-Z850 functions include "Old Photo" Best Shot Mode, which refreshes faded colors of old photos by bringing them back to life in digital format, automatically adjusts for obliquity even when photos are shot while still in the album. The Rapid Flash function enables three consecutive, high-speed flash photos in only one second, ensuring that no special moments are missed. Soft Flash, which prevents overexposure of subjects photographed up close and High Power Flash, which ensures that subjects are properly illuminated even when photographed as far away as approximately 39.7 feet. The Easy Mode setting provides a simplified, easy to understand, and convenient version of the settings menu and camera interface, designed especially for first time users but also helpful to those who prefer a basic camera settings interface as well. The BEST SHOT Button enables convenient, one-touch access to 33 scenes chosen from an image menu and providing the user with a wide range of camera settings for taking hassle-free photos every time.

The EX-Z850 has features like: "Auto Macro" mode which allows for automatic switching between macro and auto focus modes. "9-Point Multi AF" clearly indicates the areas of focus when photographing subjects with multiple focus points. The "Quick Shutter" function reduces mistakes by facilitating simple and easy high-speed focusing. "Flash Assist" mode compensates for poorly illuminated areas within the shot. "Exposure Warning" mode warns over or under exposure via an on-screen display. The "Icon Help" function provides icon guidance when adjusting camera settings. The "Direct On" button allows quick startup in both shooting and playback modes.

In addition to high-resolution still images the EX-Z850 also records movies with sound in VGA (640 x 480 pixels) size at 30 frames per second. When taking high quality long duration MPEG-4 movies, the EX-Z850 instantaneously reduces camera shake electronically. For movies taken in dimly lit environments, the "built-in" Illumination LED Light provides additional illumination of the subject. Using the "Motion Print" function, movies can be converted into a series of nine or just one snapshot for printing. Movies can be zoomed in during replay and the "Movie Editing" operation offers three ways (beginning, middle, end) to cut unwanted scenes from a movie.

Camera data is stored in its 8.3 megabytes of internal memory and on optional Secure Digital (SD) type cards. The camera is powered by a Li-ion battery that is good for up to 550 shots and is charged with the included docking cradle. Data is transferred to computer via USB and you can print directly to any PictBridge compatible printer. Still images are ExifPrint and PRINT Image Matching III compatible.
