The Panasonic GH3 isn't official yet, but that hasn't stopped Panasonic either leaking on purpose, or teasing most of the details about the new camera, expected to launch at Photokina, the German camera trade show, next week.

The camera has appeared in a 3:45 minute video showing off the key features and stuff, sample stills and video.

The video spills the beans on some of the key specs of the new camera including that it will have a new version of Panny's Venus Engine processor, a splash-proof and dust-proof magnesium alloy build and high-definition filming at up to 72Mbps and 60p.

Other specs we've worked out from the vide include a a flip-out LCD screen, a bolt-on battery pack for when you need more shots, and the ability to take pictures wherever and whenever you need to.

Expect more details from the week commencing 17 September.
