Canon PowerShot G1 X offers advanced technologies that make this camera behave like it's much larger than it really is. The compact G1 X is armed with a new 1.5-inch High Sensitivity CMOS sensor, which is larger than a 4/3" sensor and nearly as big as the APS-C-sized sensors found in professional DSLRs. This gives you a light-sensitive area which is nearly 6.3 times larger than the last generation of G-Series digital cameras and delivers a quality level that's unheard of in a compact, pocket-friendly camera.
