Manufacturer OverviewCanon U.S.A. has long been a dominant player in the film and digital camera markets, well-known for their high-quality optics, technical innovations, and aggressive product development. Over the last few years, they've developed a powerful lineup of digital cameras, ranging from surprisingly feature-rich entry-level models, all the way to the extreme high end of professional digital SLRs. Last year, their PowerShot G2 prosumer model was one of the top two or three cameras on the entire Imaging Resource site, a fact I attribute to the superb job Canon did in designing and producing it. - The G2 was one of those rare cameras that really hit all the right notes with the "enthusiast" crowd, offering a rich feature set and excellent image quality.
Now, Canon has updated the G2, calling the result the PowerShot G3. To the surprise of many, they eschewed the five megapixel sensors employed by many of their competitors in high-end prosumer models, choosing instead to stay with the proven four megapixel chip first seen in the G2. (I'm told the reason for this is that Canon was unwilling to accept the image noise tradeoff that the current crop of 5 megapixel CCDs require.) While the sensor has remained the same, numerous feature and user interface enhancements (including a new 4x zoom lens with fast f/2.0 maximum aperture) combine to result in a noticeably different user experience. Read on below for the full story, but based on my early look at the new model, I'd say Canon has come up with a very worthy successor to the wildly popular G2.
