It is the successor to the Panasonic LUMIX DMC -GH2 and was presented on 17 September 2012 at the Photokina. The launch took place in late December, 2012. It is the first mirrorless system camera that can record movies at a data transfer rate of up to 72 megabits per second or 0.54 gigabytes per minute. This value significantly exceeds that started in July 2011 maximum specification of AVCHD 2.0 of up to 28 megabits per second, which is used for comparable cameras and camcorders.

Technical Features

The camera housing made ​​of magnesium alloy is equipped with a swiveling and foldable, touch-sensitive screen, an electronic viewfinder with dioptric adjustment, a built-in flash and a hot shoe. Contrary to the original intention of camera bodies and lenses in the Micro Four Thirds system make small, the GH3 is the largest and heaviest production model of this system, however, which offers benefits in handling.

In addition to the lenses with a Micro Four Thirds bayonet lock almost all lenses can be connected with a sufficiently large image circle because of the small flange focal length of 20 millimeters across the lens adapter. The normal focal length is about 25 millimeters.

The GH3 works for both still image as well as motion pictures exclusively in Live View mode with manual focusing with software magnifier with a versatile autofocus system with contrast measurement, that can also recognize faces and track designs. With the help of the electronic shutter and still images can be recorded virtually silent.

The camera body is supplied with a lithium -ion battery and can be extended with an additional battery grip that has a trigger for portrait shots.

For shooting the GH3 has next to the built-in stereo microphone also has a connector for external microphones.

About a Wi-Fi connection, the camera of smartphones, tablet PCs or mobile and stationary computers can be controlled and read out. In this case, these devices can also record the geographical coordinates of the location and add it to the metadata of the recordings.

The camera images can be transmitted directly to compatible monitors and televisions also also, though not during recording.

Use in film productions

The ability to films with very large data transfer rate in Full HD (1080 x 1920 pixels, 50 frames per second for the European version, 60 frames per second for the U.S. version ) using the H.264 standard (MOV (IPB ) to 50 megabits per second), in the AVCHD 2.0 standard ( up to 28 megabits per second ) or 25 frames per second in all- intra standard to (Recording with 72 megabits per second) and with powerful lenses, and the connection for external microphones make the GH3 interesting for high-quality film productions. The video recording can also be done in slow motion or time-lapse and be provided with a SMPTE timecode.
