Panasonic LUMIX GH3 makes premature appearance

Panasonic has stolen its own thunder with the LUMIX GH3 micro four thirds camera, pre-announce posting a video of the new model and spilling its 16-megapixel sensor and 72Mbps video recording. The GH3 inclues a new Venus image processing engine and is clad in a magnesium alloy casing that, Panasonic says, is dust- and splash-proof.
