The camera GH4 enables shooting at maximum ISO 25,600, boasts high speed burst shooting at 12 frames per second (AFS) up to approx.40 (including RAW) / approx.100 (excluding RAW) and 7.0 fps(AFC) to capture fast moving subjects.
The new GH4 has evolved into a professional video camera. One of the most prominent advances is unlimited 4K video recording (Cinema 4K: 4096x2160 / 24 fps and QFHD 4K: 3840x2160 / up to 30 fps) in MOV/MP4. The GH4 is also capable of recording Full-HD video with ultra high bit rate at 200 Mbps (ALL-Intra) or 100 Mbps (IPB) without recording time limit. Users can choose the format from MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates according to the usage. For professionals working globally, the system frequency can be selected between 59.94Hz (23.98Hz) / 50.00Hz / 24.00Hz. The GH4 is also capable of real-time image output (in 4:2:2 / 8-bit and 4:2:2 / 10-bit) to an external monitor via an optional micro HDMI cable simultaneously while recording video. For more unique video expression, VFR (Variable Frame Rate) enables recording video with slow/fast motion such as 96 fps, 4x, all in Full-HD. Time Lapse/Stop Motion Animation can be also produced with GH4 without postproduction processing.
The GH4 complies with UHS Speed Class 3 (U3) standard, which guarantees a constant minimum write speed of 30MB/s.
The Contrast AF system in the GH4 is further enhanced by Panasonic's integration of DFD (Depth from Defocus) technology which shortens the time to focus to achieve ultra high speed AF of approx.0.07 sec. Operability is enhanced thanks to the addition of Face / Eye Detection AF or 49-point AF with Custom Multi AF mode.
The GH4 boasts dual OLED (Organic Light-Emitting Diode) displays of 2,359K-dot LVF (Live View Finder) and 1,036K-dot rear monitor. Notably, the OLED for the LVF in GH4 boasts 10,000:1 high contrast.
To be tough enough to withstand heavy field use, the main structure of the GH4 is composed of a magnesium alloy full die cast front/rear frame. It also features splash / dustproof construction by sealing every joint, dial, and button. The shutter unit allows a max. 1/8000 shutter release and is also redesigned to be even more durable for approx. 200,000 actuations.
The GH4 integrates Wi-Fi connectivity (IEEE 802.11 b/g/n) with NFC (Near Field Communication) technology camera to offer image sharing with easy operation.
The new camera will be released globally this spring.
