Panasonic has posted the promised firmware updates for its movie-focused Lumix DMC-GH3 mirrorless camera, the 14-42mm and 45-175mm power zooms and the 45-150mm lens. The GH3 update adds the ability to shoot 1080p60 footage in MP4 format and lets users connect to a computer via Wi-Fi by entering the computer name (NetBIOS names for Mac). Meanwhile the lens updates promise improved autofocus performance in AF Continuous mode when mounted on the GH3.
