Like the GH3 before it, the GH4’s trump card is shooting video. Video capabilities offered by the camera include ultra-high-bitrate 4K (100 Mbps) and Full HD recording (200 Mbps); global frame rates, allowing professionals to shoot for overseas markets; and Variable Frame Rate for slow and fast motion shooting at up to 96 frames per second in Full HD. A new optional interface unit ensures high performance when connecting to external monitors and recorders.
Panasonic has developed the interface unit (AG-YAGHG) exclusively for professional workflow with the GH4, enabling more powerful video transmission. It complies with Full HD (4:2:2 / 10-bit) four parallel outputs and these can be used for 4K (4:2:2 / 10-bit) output – both with time code. The XLR input terminals (2ch) are also equipped to connect a line or condenser microphone. When connecting with a microphone, volume can be controlled for L and R separately, and can be monitored via the LED audio level display on
the back of the unit. The 12V DC IN is highly compliant with large-capacity professional batteries and continuously supplies the GH4 with power.
Shooting stiills, the 16-megapixel (Live MOS) GH4 delivers high-speed burst shooting at 12 frames per second at full resolution, supported by a 40-shot buffer for RAW images; Contrast AF performance is claimed to be .07 sec, with improved continuous focus. Maximum shutter speed is 1/8000 sec shutter speed. A 2.4-million-dot OLED viewfinder and a 1.04-million dot monitor offering higher resolution and greater precision; and the ability to process Raw photos in-camera.
Other features include focus peaking, low-light AF, and 49-area AF (increased from 23-area). The weather-sealed DMC-GH4 also has a shutter designed for a lifespan of up to 200,000 cycles, double that of most cameras in its class.
In addition, the camera’s Wi-Fi connectivity has been enhanced with NFC for simple pairing with a smartphone or tablet, with QR code scanning available for non-NFC devices. Optional accessories include a powerful GN58 hotshoe flash and a Stereo/Shotgun Microphone.
Panasonic now has 22 Lumix G digital interchangeable lenses in its range.
At the same time, Panasonic also announced the new Gold Series ‘SDUC’ cards, which are compatible with UHS Speed Class 3 for 4K video recording.
Neither worldwide nor local pricing and availability dates for the new Lumix GH4 camera and Gold Series SDUC cards have been provided in the Panasonic press materials.
