Canon PowerShot G7

Canon have just announced the PowerShot G7. The latest in Canon's top-end "G" series of compact cameras, the G7 is smaller than its predecessors (it's about the size of an A-series camera), features 10 megapixels, gyroscopic image stabilisation, sensitivity up to ISO 1600, and a new DIGIC III image processor. Gone, however, are the fold-out LCD screen (which was convenient for shooting over crowds, for example), and the RAW mode (which, presumably, is for DSLRs only these days).

Given its small size, I have some doubts over the image quality, in particular the dynamic range. I have a PowerShot A620, and have found that, when shooting images with ranges of colour, often the image quality is flat and washed-out, in a way that it wasn't with my old PowerShot G2. If this is due to the physical constraints of the sensor size, then unless Canon have since had a breakthrough in sensor engineering, it is unlikely that the new top-of-the-range G series will deliver any better performance than a humble A. I'd have to see results before I'm convinced that the G7 is a worthy successor to earlier G cameras.

Having said that, it sounds like a very good camera for shooting at gigs and such, having both IS and ISO 1600 (and the whole thing costing less than half the price of a good IS zoom lens for a DSLR.
