Panasonic launches Lumix G X Vario PZ 14-42mm F3.5-5.6 OIS pancake: Digital Photography Review. Due to the development of Sony, I am tempted to sell my Panasonic device and focus entirely on the larger chip (and possibly add a NEX 7), but this pancake zoom from Panasonic is really appealing for a compact setup. Even on the GH1, it would then be an impressively compact but flexible package.
