2.4The Canon PowerShot G9, part of Canon’s line of high-end compact digital cameras, was introduced a year after the G7 hit the market. The G9 boasts more resolution and added RAW shooting capability, as well as a new image processor, the Digic III, which improves on its face detection technology. The 12.1-megapixel Canon G9 has the same optically stabilized 6x zoom lens and manual functionality its predecessor had, but while the G7 started out at $599, the new G9 retails for $499.
