The Panasonic Lumix DMC-GH4 is a Micro Four Thirds System digital still and video camera originally released in May 2014. At the time of its release, the GH4 was notable for being the world's first Mirrorless interchangeable-lens camera with 4K Video recording capability.
The GH4 is largely physically similar to its predecessor, the Panasonic Lumix DMC-GH3, adding only a locking mode dial and more detailed rear LCD screen and Electronic Viewfinder.
The emphasis of the camera is the video with Venus Engine IX processor allow for 4K video and 12 fps continuous shooting. As a 4K video camera, it can be categorized as a pro-level video camera that can record in Cinema 4K mode (4096 x 2160) or standard 4K-UHD (3840 x 2160) using IPB compression in 100Mbit/s. In Full 1080p HD there are two options, 200Mbit/s in ALL-Intra compression, or 100Mbit/s with no recording time limit. The camera also provides .mov, mp4, AVCHD Progressive, and AVCHD video formats at a variety of frame rates according to the usage; and options for VFR (Variable Frame Rate) or Time Lapse/Stop Motion Animation without the need for post-production processing.
Autofocus needs only 0.07 seconds with the 'Depth from Defocus' autofocus system. The camera also has Wi-Fi with NFC, PC sync port, highlight and shadow control, and a 'silent mode' which uses the electronic shutter only. Video features added to the DMC-GH4 include Focus peaking, zebra overlay, luminance level adjustment, and cinema gamma presets.
