Canon G15 review What does this upgrade of the popular G12 offer?
A lot has changed since the Canon G12 was first debuted, and it's a shame that more excitement couldn't have been allocated to the Canon G15. For instance, a touchscreen, GPS and Wi-Fi would have been a welcome addition. Instead, it feels a little as if the G series has stagnated a little.

Canon PowerShot G15 review
The G15 is an evolutionary update from the G12, and on the whole the changes Canon has made look sensible and well-considered. The camera is clearly a well-refined product and a joy to use. It is very quick and responsive in operation, built like a tank and offers the most external controls in its class.
