Panasonic announce Mirrorless 4K GH4 Camera
Panasonic has announced a 4K mirrorless camera in the shape of the new Lumix GH4
The Panasonic LUMIX DMC-GH4 (full title) is the world’s first DSLM with 4K recording capability and features a newly developed 16.05-megapixel Digital Live MOS Sensor. The Venus Engine image processor has also been newly developed, with a claim of a dramatic boost in performance with its new quad-core CPU that allows for the high speed signal processing necessary for 4K video capture.
There are also some improved noise reduction systems, allowing the GH4 to shoot at maximum ISO 25,600. Sensitivity, gradation performance, resolution and colour reproduction are also said to be vastly improved.
The GH4 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.
World’s first DSLM with 4K recording capability
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. Formats supported include MOV, MP4, AVCHD Progressive and AVCHD at a variety of frame rates.
For professionals – or prosumers - 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 to an external monitor via an optional micro HDMI cable simultaneously while recording video.
For more unique video expression, VFR(Variable Frame Rate) or Time Lapse/Stop Motion Animation can be produced with GH4 without postproduction processing.
The high-precision Contrast AF system in the GH4 is 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.
The GH4 also boasts newly developed dual OLED 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.
Pricing and availability will be announced at a future date.
