The PowerShot G1 X Mark III is Canon's first compact camera that is equipped with a APS-C size CMOS sensor and high-performance and enhanced functions, such as high-speed and high-precision AF, a 3X optical lens, dust- and drip-proof capabilities, electronic viewfinder, and vari-angle monitor, all condensed within a single unit. The design allows for complete compactness/lightness, a comfortable grip and optimal operability, resulting in the ultimate all-in-one camera that users can carry around everywhere.
