Features of the GH4 include a newly developed 16.05-Megapixel Digital Live MOS Sensor and Venus Engine for high speed, high sensitivity image recording. The camera was also designed with high speed response required for professionals and practical auto focus options. Wireless connectivity is possible via Wi-Fi or NFC with smartphones. In-camera imaging options of the GH4 include Luminance Level Adjustment, Focus Peaking, Silent Mode, Highlight/Shadow Control and RAW data development.
Features of the 4k Video Adapter include XLR monaural 2ch terminals (Line Mic/Condenser Mic. Input), Audio level display monitor, and 3G-SDI video output terminal plus time code. The adapter will add another 24.46 oz (750 g) to the overall weight of this combo.
The camera system will be available starting in May at shop.panasonic.com and other retailers that sell photographic equipment.
Panasonic says the current GH3 model will continue to be available after the introduction of the GH4.
