Canon has unveiled a new PowerShot compact camera with a large zoom and resolution. The PowerShot G3 X packs a one-inch, 20.2-megapixel CMOS sensor with a DIGIC 6 image processor into a dust and water-resistant case, while on the front is an f/2.8-5.6, 25x optical power zoom lens, the equivalent of 24-600mm lens, which also benefits from an improved five-axis Intelligent Image Stabilization system for clearer images.
