PowerShot G3 -Winning technology for even better performance than before

Amstelveen, 16 September 2002 – Canon introduces the PowerShot G3 – the third generation model in the “G” series line-up of digital cameras. Aimed at the advanced amateur and semi-professional users, this new model boasts a 4x zoom lens with fast f2.0 – 3.0 aperture, a new DIGIC processor and 4 Megapixel CCD sensor.

The PowerShot G3 improves further on the EISA award winning PowerShot G2, which was voted European Digital Camera of the Year Award 2002. The PowerShot G3 features a newly designed, high quality, 35-140mm (35mm film equivalent) zoom lens with f2.0 – 3.0 aperture the first 4x zoom lens on a PowerShot digital camera. The fast f2.0 – 3.0 aperture ensures superb picture quality even in low light situations and the 4x zoom gives wider range of viewpoints for every scene.

The PowerShot G3 sees the introduction of the new ultra-fast DIGIC (DIGital Imaging Core) processor. ” DIGIC is not just a cosmetic change”, says Mr. Komatsuzaki, executive Vice President, Canon Consumer Imaging. “This development will advance image quality and camera performance even more than what has already been voted European Digital Camera of the Year.”

Quality and Technology

The new PowerShot G3 offers photographers the best ever image quality. Delivering high definition and fast processing with a new imaging processor ‘DIGIC’ for enhanced picture quality, improved AF accuracy as well as speed of operation.

The 4Megapixel CCD sensor ensures the best image quality at the highest resolution and the DIGIC processor gives improved shadow and highlight details for even better quality images. Now the highest quality RAW mode is accessible even when shooting in JPEG. Immediately after taking a shot the image is displayed on the LCD, simply press the camera’s function button and you can change to store the file as RAW, offering more options for highest quality processing on the computer.

Canon has designed the DIGIC processor specifically for great image processing. Combining the 6 key elements of CCD Control, AE/AF/AWB, signal processing, JPEG compression, memory card control and LCD monitor display, the PowerShot G3 delivers better quality images than it’s predecessor, and with the speed advantage of DIGIC, battery life is improved too. The DIGIC processor is a major component essential to ensure the image quality that is a Canon camera hallmark.

Intelligent Scene Analysis based on Photographic Space (iSAPS) is another technology that allows the PowerShot G3 to deliver superb images. With the new iSAPS technology Canon utilises 60 years of camera experience even before a picture is taken. The scene focussed on and shooting information are analysed and cross-referenced against Photographic Space data.

Photographic Space data is a vast library of statistical information built into every new Canon digital camera. By taking advantage of Photographic Space the camera’s performance parameters are optimised to better to render the scene as the photographer intended.

Flexibility and Creativity

Designed for true creativity and flexibility the PowerShot G3 combines a host of advanced Canon technologies to deliver outstanding image quality and flexibility in every shooting situation.

With 12 shooting modes including full two custom modes, manual control, selectable focusing points and metering modes the PowerShot G3 ensures that technology need not hamper creativity. The PowerShot G3 also features FlexiZone AF/AE which means there’s complete control of the position of the focus and exposure point in the viewfinder frame, ideal for off-centre and even on-the-edge compositions.

The PowerShot G3 has the most comprehensive auxiliary flash system of any digital compact camera in the world, offering the advanced amateur and semi- pro more creativity. This camera is compatible with the complete range of Speedlite EX flashes including the Macro-Ring Lite MR-14EX and the Macro Twin Lite MT-24EX. The PowerShot G3 provides many add-ons for maximum flexibility. With both a 0.7x wide converter, and 1.75 x tele-converter the zoom can be extended to cover from 24mm to over 240mm (35mm-film equivalent) – 10x zoom.

Directly connectable to all Canons’ Direct Printers, The PowerShot G3 delivers superb quality photo images totally bypassing the PC. Simply connect the camera to a Canon direct printer; select the desired shot and a full colour 10x15cm or A4 size photo is easily printed in minutes.

Design and Ergonomics

A new Main dial has been added to the handgrip of the PowerShot G3 for ease of movement. This main dial is similar to that on the EOS system cameras and has the effect of increasing/decreasing the value of selected features. By pressing the dial a different feature and or option will be selected and can thus be easily adjusted.

A vari-angled 1.8-inch LCD monitor, similar to that used in the popular PowerShot G2, gives the photographer 100% coverage. The LCD monitor can be independently positioned to view the scene regardless of the position of the camera; great for macro photography close to the ground.. When the LCD monitor is rotated towards the front for self-portraits, a mirror image is displayed for correct viewing.

More information has been added to the top LCD of the PowerShot G3 to increase usability of the camera, especially when the main colour LCD screen is turned off.
