Canon made headlines with the 5D Mk. II’s ability to shoot high definition video in 1080p. This was a major development as it allowed photographers the ability to get a big movie look to the videos shot. This was because it brought lenses, shutter and aperture settings and depth of field to video. And it looked like a million. Panasonic sees the handwriting on the wall that convergence is the watchword in photography. But they’ve upped the ante to the next level with the Lumix GH1, which can not only shoot 1080p video, but it also adds Dolby digital audio to the mix, meaning photographers have a serious movie studio in their camera.
