I love my Canon G7. It can accidently take a great photo - in the right hands it's very powerful

“The PowerShot G7 brings a new level of performance and usability to the G series,” said Mogens Jensen, Head of Canon Consumer Imaging Europe. “By introducing our DIGIC III image processor and new technologies such as Face Detection AF/AE, Canon continues to raise the benchmark for digital compact cameras."
Image Quality and Optics
The PowerShot G7 delivers the image quality and optical performance demanded by advanced photographers. A 10.0 Megapixel sensor captures enough fine detail to ensure large photo quality prints with added cropping flexibility. The fast f/2.8 (W) – f/4.8 (T) 6x optical zoom lens (35-210mm focal length, 35mm equivalent) incorporates optical Image Stabilizer technology to counteract the effects of camera shake, allowing the camera to be used at slower shutter speeds in low light conditions. The lens configuration consists of 9 elements in 7 groups and includes a double-sided aspherical lens element to counteract common lens distortions. The addition of Canon’s SR lens coating – a first for Canon's digital compact camera range – significantly reduces the problem of ghosting and virtually eliminates chromatic aberration.
DIGIC III
Canon’s new DIGIC III image processor drives improved responsiveness and colour rendering along with increased noise reduction, extending the camera's ISO range to ISO 1600. A dedicated ISO dial makes it simple to switch between settings. Complementing DIGIC III's performance, the camera features the same DDR-SDRAM used in professional EOS cameras – raising the data throughput rate substantially.
Face Detection AF/AE
For portrait and group shots, the PowerShot G7 is equipped with Face Detection AF/AE, a new Canon technology that automatically detects up to nine faces within a frame and sets the optimum focus and exposure accordingly. If there is more than one face in a frame Face Detection AF/AE is able to determine the face or faces intended to be the main focus. The system operates at the same speed as Canon’s established 9-point AiAF system, which it automatically reverts to if no face detection is required or intended.
Designed for photographers
Referencing classic rangefinder cameras, the ergonomic design features analogue inspired controls, a multi-control dial and a customisable shortcut button for faster access to camera settings. Usability is further enhanced with a high resolution (207,000 pixels) 2.5" LCD. The low-reflection screen coating aids visibility in sunny conditions while a wide viewing angle helps with group viewing or and aids more creative framing options.
A selection of 25 shooting modes includes full Manual and two custom settings, enabling users to tailor the camera to their specific preferences. Shooting modes are complemented by advanced settings such as AEB (auto exposure bracketing), focus bracketing, and an integrated neutral density (ND) filter with 3 stops adjustment. Photographers can also take advantage of second curtain flash synchronisation for creative flash exposures, while interval shooting (up to 100 shots in 1-60 minute increments) allows for extended time-lapse photography of up to four days.
Advanced movie functions include high resolution XGA (1024 x 768 pixels) video capture with sound at 15fps. Users can also record VGA and QVGA movies at a smooth 30fps.
A new Safety Zoom feature allows users to extend the camera's zoom range without interpolation affecting image quality. Images can be captured at up to 14x zoom with enough resolution for lab-quality postcard (10 x 15cm) prints. Photographers can also enable the Digital Tele-Converter3 feature for added telephoto reach on every shot, without the reduction in aperture typically caused by optical tele-converters.
Accessories
In addition to Canon Speedlite support, the PowerShot G7 is compatible with a range of optional lens accessories, including wide (0.75x) and tele (2.0x) converter lenses. A waterproof case allows for shooting at depths of up to 40 metres.
