Panasonic has announced a new interchangeable lens mirrorless camera called the DMC-GH4. The camera has a 16.05 megapixel Digital Live MOS sensor with a quad-core Venus Engine Image processor that can shoot at up to ISO 25,600 along with 12fps single auto-focus or 7fps continuous auto-focus burst mode. But none of those are its main feature.
The GF4 is the first camera in its class to support 4K video. It can record in the Cinema 4K resolution of 4096×2160 at 24fps or QFHD resolution of 3840×2160 at 30fps. The camera can also record 1080p video at up to 200Mbps bitrate at ALL-I or at 100Mbps IPB. The GF4 can do so without any time limits and in either MP4, MOV, ACHCD or AVCHD Progressive formats at 59.94Hz, 50Hz or 24Hz. You can also output 10-bit 4:2:2 raw footage through HDMI out to an external monitor or a recorder.
The GF4 has Zebra Pattern that will place black and white stripes on over exposed parts of the image to help correct exposure and focus peaking to help you manually focus. There is also a new 49-point Depth from Defocus auto-focus system that helps the camera focus in just 0.07 second. Other features include a 3.0-inch, 1036k dot OLED display and 2359k dot OLED electronic viewfinder, NFC and Wi-Fi.
The Panasonic DMC-GF4 is quite an impressive-sounding video camera hiding inside what looks like a traditional DSLR and comes with a ton of features that serious videographers will find useful. Unfortunately, no price and availability information has been announced so far.
