The Powershot G series has represented a fairly formidable presence at the top of the compact camera tree. From a keen photographer point-of-view, there's little on the market that can match its mixture of zoom range, lens flexibility, build quality and level of manual control. Somehow Ricoh's GX and Nikon's P series have never quite had the same impact but Panasonic's LX3 has been enough to tempt some potential customers away, with its bright lens and convincing (for a compact) low-light performance.

The G11 seems determined to wrestle back its position as undisputed champion of the market, though, incorporating what Canon describes as a 'high sensitivity' CCD. In what might be a first, the company has reduced the pixel count in comparison to the preceding model. In principle, there is no disadvantage to having more pixels when you consider the whole image (other than the larger file sizes that might slow down the camera and fill your memory card faster and the added complication of having to apply noise reduction before demosaicing, which is not something many people are willing or able to do). However, the often larger photosites of a less pixel-dense sensor will tend to receive more light, in the same exposure, making it easier to produce an image that looks cleaner at the pixel level. Almost as if Canon wants its flagship compact to be a handy all-rounder. Read rge excellent review here. You can buy the camera here.
