Panasonic followed up on its self-leak today by officially rolling out two new Micro Four Thirds cameras. Of the pair, the Lumix G2 is the first swappable-lens camera to use a swiveling touchscreen; photographers can now not only preview shots off-angle with the 3-inch LCD but control the camera at the same time, including tap-to-focus AF. It simultaneously represents the first in-between video-capable Lumix G as it can record at 720p30 in H.264, which trails the GH1's 1080p24 but saves space.
