Not taking cues from a certain other manufacturer that unveiled well over a dozen models last week, Canon is adding just two cameras to its PowerShot ELPH family, in addition to the just-announced PowerShot G1 X. The 10.1 megapixel ELPH 520 HS and 16 megapixel ELPH 110 HS both include high-sensitivity CMOS sensors, sensitivity up to ISO 3200, 1080p video capture and 3-inch LCDs. The pricier 520 HS has a 12x wide-angle (28mm) optical zoom lens and can capture burst images at 6.8 frames-per-second, while the 110HS has a 5x optical zoom lens starting at 24mm
