As expected, Panasonic today launched the Lumix GF1, its own take on the idea of a rangefinder-like Micro Four Thirds camera. In addition to being slightly smaller than the Olympus E-P1 it shares its system with, the GF1 has a surprise fix for the absence of built-in flash on its competitor: the corner opposite the grip has a hidden pop-up flash that properly distances the illumination from the lens. No viewfinder is built-in, but an optional electronic viewfinder provides 100 percent coverage regardless of lens.
