The Lumix GH3 was the third iteration of the video oriented GH-series camera from Panasonic. The GH3 offered quite a number of improvements over its predecessor, the DMC-GH2. The GH3 features higher video bit rates, a magnesium shell, an electronic shutter, integrated Wi-Fi, better ISO performance, higher image frame rate, manual zebra focus assist, and a greater detail viewfinder.
