It must not have been quite ready for this year's Photokina, which was when Panasonic introduced their SLR-like DMC-GH2, because today Panasonic unleashed the extremely compact Micro Four Thirds contender that is the DMC-GF2. According to the press material, the GF2 is 19% smaller and 7% lighter than its predecessor, the GF1. But, despite the shrunken body, it still manages to retain the built-in flash and compatibility with Panasonic's new 3D lenses.
