When it was released in 2009, Panasonic billed the Lumix DMC-GF1 as 'the world's smallest and lightest digital interchangeable lens system camera with a built-in flash'. Sporting a new 'artistic flat' body design similar to that of the (then) recently released Olympus E-P1, the GF1 is 35% smaller than earlier G models like the G1 and GH1. Headline features include the same 12.1Mp sensor as the DMC-G1, 1280 x 720 HD recording in AVCHD Lite format, an optional hot-shoe mounted electronic viewfinder, and a 3 inch LCD with 460k dots.
