“These two new cameras epitomize everything the A-Series stands for,” said Mogens Jensen, Head of Canon Consumer Imaging Europe. “Combining user-friendly design with advanced functionality, they will appeal equally to novice users and serious photo enthusiasts.”

Quality control

The 10.0 Megapixel (PowerShot A640) and 8.0 Megapixel (PowerShot A630) sensors allow for creative cropping while providing enough detail for large, high quality prints. A new Safety Zoom takes advantage of the cameras’ Megapixels to offer extra zoom magnification without affecting image quality – up to 16x zoom when shooting Small size images. Users can also activate the Digital Tele-Converter to add extra telephoto reach on all shots, similar to adding a tele-converter lens to the camera.

The 4x optical zoom lenses achieve a 35-140mm focal length (35mm equivalent) while allowing the cameras to maintain a compact size. The lens construction incorporates 8 elements in 7 groupings, including two aspherical elements to maximise sharpness across the whole image. With a maximum aperture range of f/2.8 (W) to f/4.1 (T), the lenses are remarkably bright at the telephoto end.

ISO 800 mode improves results when shooting in low light settings and enables flash-free photography indoors. The cameras’ High ISO Auto setting prioritises fast shutter speeds by automatically using the higher range of ISO sensitivities, reducing the risk of unwanted image blur.

Improved LCD and playback

A larger 2.5” vari-angle LCD screen enables accurate framing from unusual angles, such as those encountered when using the 1cm Macro mode. The enhanced user interface (UI) retains a selectable Grid Line display to assist with rule-of-thirds compositions, while users can also enable a new 3:2 ratio overlay during shooting to view the printable area for standard photo prints. Playback is enhanced with an overexposure warning feature, which indicates overexposed areas in captured images.

Flexible shooting

The PowerShot A640 and PowerShot A630 offer users a range of versatile features for creative photography. A choice of 21 shooting modes includes Program, Aperture priority, Shutter priority and full Manual modes for complete exposure control. A Second Curtain Sync function on both cameras allows for creative flash exposures, such as light trails. Artistic photo effects can be applied in-camera during and after shooting with My Colors. Filming is also possible at a high standard – VGA quality movies can be captured with sound at a smooth 30 fps. The AV Out connection and supplied cable allows for full screen playback on a TV.

Full range of accessories

A comprehensive range of optional lenses and accessories includes Wide (0.7x) and Tele (1.75x) converter lenses. The optional High Power Flash offers further flexibility for night time photography, while an optional waterproof case allows full control at depths of up to 40 metres.

Technologies Explained

DIGIC II

Canon’s purpose-built DIGIC II (DIGital Imaging Core) image processor links all primary camera functions for maximum efficiency. DIGIC II processes signals at high speeds, resulting in outstanding responsiveness, rapid auto focus and extended continuous shooting ability. Advanced image processing algorithms deliver superb image detail and colour reproduction with accurate white balance and minimal noise. DIGIC II operates efficiently to extend battery life, for longer shooting on a single charge.

iSAPS

iSAPS (Intelligent Scene Analysis based on Photographic Space) automatically optimises key camera settings before every shot. Each scene is analysed and cross-referenced against Photographic Space – a vast in-camera library of photographic data. This enables the camera to make optimal adjustments to auto exposure, auto focus and auto white balance before image capture occurs.

9-Point AiAF

Canon’s 9-point AiAF (Artificial Intelligence Auto Focus) automatically scans and selects subjects from a set of nine focusing areas across the scene. This ensures accurately focused images even when subjects are not in the centre of the frame.

FlexiZone AF/AE

FlexiZone AF/AE lets users manually select the focus point from almost any point in the frame by moving the auto focus window in the viewfinder. Exposure can be linked to the focus point to ensure that the chosen subject is accurately focused and the scene correctly exposed.

Digital Tele-Converter and Safety Zoom

Similar to placing an accessory lens on the front of the camera, Canon’s Digital Tele-Converter adds a constant digital zoom to every shot (PowerShot A640: 1.4x /2.3x, PowerShot A630: 1.6x /2.0x). While optical converter lenses cause a reduction in aperture and consequently require a slower shutter speed, the Digital Tele-Converter maintains aperture size, reducing the risk of image blur. Safety Zoom protects the image from interpolation at high levels of digital zoom, allowing users to extend zoom magnification without sacrificing image quality.
