The sophisticated $600 Canon PowerShot G7 boasts a 10-megapixel sensor, face-detection autofocus, optical image stabilization, and a maximum light sensitivity of ISO 1600. In contrast, the PowerShot G6 had a 7.1-megapixel rating, lacked image stabilization, and reached ISO 400.
The compact G7's rugged, bricklike metal body feels as though it could weather a few knocks. Its black exterior gives the camera a serious look.
