It's a very busy CP+ for Canon. The camera maker has a handful of new models for the show, including one of the waterproof variety. The PowerShot D30, which replaces 2012's D20, boosts the waterproof rating from 33 feet to 82 feet, making it a suitable choice for all but the deepest scuba dives. There's a 12.1-megapixel CMOS sensor, a DIGIC 5 processor and support for 1080/30p video. The 5x 28-140mm lens isn't as fast as we'd like for dim underwater shoots, with an f/3.9-4.8 maximum aperture, but with the ISO bumped up a bit, it should perform decently. You can frame shots on the 3-inch 461k-dot LCD, which sports a sunlight mode for use in brighter conditions. The camera is shockproof and cold-resistant as well, and while there's no WiFi on board, it does include GPS. The PowerShot D30 is expected in stores by mid-April with a $330 MSRP.
