The new GH3 can record 1080p video at up to 72Mbps using an ALL-I codec, as well as 50fps in AVCHD mode, at 28Mbps. The camera is based around a 16 megapixel Live MOS sensor, and can record in MP4, MOV (Quicktime) and AVCHD. The ISO range is 200 to 12,800. Full time AF in video mode – a popular feature on the GH2 – has been retained.
The camera keeps to the small and light format set by the GH2: at 550g it is lighter than both the Nikon D600 and the Canon 6D. But Panasonic has added a range of more professional features to the camera, including an optional battery grip, for extended shooting times, and a 3.5mm microphone jack in place of the GH2’s 2.5mm model. There is also a headphone socket, and a clean video output via HDMI.
The GH3 records files to a single SD card slot which supports up to UHS-I. Recording time is stated by Panasonic as up to 240 minutes in AVCHD. However, in the EU, this is restricted to 29 minutes and 59. The camera also supports timecode, with free run and record run options.
Panasonic is promoting the new camera with its f2.8 12-35mm zoom lens, which supports optical image stabilisation but not power zoom.
