Casio updates the Exilim EX-Z3
(Wednesday, August 27, 2003 - 05:37 EDT)

9AM ET: Casio Computer Co. Ltd. and its US subsidiary Casio Inc. will today announce several new addition to their Exilim series of ultra-compact digital cameras in a "credit card" form factor (apparently European countries were given a different NDA time to the US).

One of the announcements, the EX-Z4U looks to be closely based on the existing EX-Z3 model, with the same Pentax 3x optical zoom lens, but a new 4.23 megapixel CCD image sensor. (The other announcements are covered in a separate news item). The EX-Z4U can now take exposures as long as 4 seconds and has a maximum ISO rating of 400 - the previous model was limited to just 1 second and ISO 200. The movie mode of the EX-Z3 seems to have been removed, and a new audio recording mode added in its place. The camera body seems to be almost identical to the EX-Z3, although we've yet to receive any pictures of it from Casio - the dimensions of the EX-Z4U are the same, and the weight is just a touch more.

The Casio Exilim EX-Z4U will ship in October at a price of $399.99. Specifications courtesy of Casio follow; we've yet to receive any pictures of the cameras from Casio, and will update this item once they are available:

Original Source Press Release:


The EX-Z4U is a stylish, thin, card-size digital camera with high-resolution 4 megapixel CCD and 3X seamless optical zoom that you can take anywhere!

DOVER, NJ, AUGUST 27, 2003 – Casio, Inc., in conjunction with its parent company, Casio Computer Co., Ltd. today announced the EXILIM ZOOM EX-Z4U, the latest addition to the EXILIM Series of card-size LCD digital cameras. The new EX-Z4U features a CCD with 4 million effective pixels plus a high-performance 3X zoom lens.

EXILIM is the digital camera that has totally revolutionized digital imaging, with a new design that makes it easy to enjoy the advantages of having your camera anywhere you go. Its combination of outstanding portability and high performance has made the slim, card-size optical zoom EXILIM ZOOM the pacesetter in the shift to compact and thin packages in today's digital camera market.

The new EX-Z4U packs the first high-resolution 4-megapixel CCD of the EXILIM lineup into a stylish and thin card-size body. The result is a powerful 3X optical zoom camera that can be taken just about anywhere.

The EX-Z4U will retail for $399.99 and will be available in October 2003.

“The EXILIM line of digital cameras has been one of Casio’s greatest innovations to date,” said John Clough, president of Casio, Inc. “They have truly captured the imagination of the American public and have become popular fashion accessories as well.” Clough said that the camera fits into pocket or purse and is extremely easy to use. “This latest 4 megapixel EXILIM provides spectacular image quality capable of capturing the finest detail. It’s truly one of our most spectacular product introductions to date,” Clough concluded.

  • 3X optical zoom lens in a thin, card-size configuration
    The new EX-Z4U packs a powerful 3X optical zoom lens into a stylishly thin card-size package that measures a mere 3.43” wide, 2.24” high, and .93” thick (.78” at its thinnest point).
  • High-resolution 4-megapixel imaging
    The 4-megapixel CCD of the EX-Z4U adds new dimensions to flesh tones and the fine detail of scenery shots for images of exquisite beauty and definition.
  • High-speed response
    With a start up time of approximately 1.6 seconds (with flash turned off) and a 0.01 second release time lag*, the EX-Z4U is faster than ever. A new Pan Focus mode eliminates the need for focusing, which provides even faster response. Multi-Auto Focus automatically selects one of seven different focus point positions to ensure that images are always focused correctly, regardless of how the subjects are arranged.
    * Time from when the shutter release button is fully depressed with the monitor screen and built-in flash turned off, and focus locked.
  • Built-in speaker for audio output
    New audio snapshot and voice recorder capabilities have been added, and a 2-inch monitor screen and built-in speaker lets you enjoy playback of both images and audio. Sounds can be specified for start up, shutter release and other functions.
  • Designed and engineered for ease of use
    A low-power design has extended battery life to allow approximately 540 snapshots to be taken (continuous recording). Other functions include high-speed playback capabilities that let you scroll images at about 0.1 second per image, and a Best Shot mode that uses preinstalled sample scenes to help set up the camera’s functions faster, and more.

  • 4-million effective pixel CCD for high-resolution images, with new noise reduction process for outstanding image quality, especially when shooting at night.
  • Built-in speaker for playback of voice recordings and audio snapshots
  • High speed startup has the camera ready to shoot about 1.6 seconds after power on (when built-in flash is turned off).
  • A release time lag of only 0.01 second (monitor screen and flash off) means that an image starts to be recorded virtually as soon as you press the shutter release button.
  • Pan Focus mode eliminates the need for focusing, for even faster response.
  • A seven point Multi-Auto Focus function automatically selects the optimum focus point.
  • High-speed playback scrolls at a speed of about 0.1 second per image, making image searches quicker and easier.
