The continuing popularity of its less-expensive but last-generation PowerShot S3 IS and its competitors around the $300 price mark such as the Panasonic Lumix DMC-FZ8 and Kodak EasyShare Z712 IS has likely driven Canon's decision to release a new megazoom option in that price class. The PowerShot SX100 IS, which Canon expects to ship in early October for $299, offers some attractions over the S3 IS, but makes some tradeoffs as well.

Given its specs, the SX100 has a confusing market fit. Its aforementioned competitors sport 12X zoom lenses but 7-megapixel sensors; however, you're generally better off with the longer lens and the smaller sensor. And I'm no big fan of electronic viewfinders (EVF), but I don't know that dropping it entirely is such a good idea. However, it will certainly be an interesting camera to look at when the time comes.
