Panasonic has announced its latest flagship Micro Four Thirds camera, the Lumix DMC-GH4. And the confirmed video specs are game changing…
Its revised 16MP Live MOS sensor and Venus Engine IX processor allow for 4K video and 1080p shooting at bitrates as high as 200Mbps, with support for the IPB and ALL-Intra codecs. Features include focus peaking, zebra pattern, luminance level adjustment, and cinema gamma presets. An optional ‘interface unit’ adds five SDI and two XLR terminals, and permits 10-bit 4:2:2 output with time code.
The GH4 uses a new ‘Depth from Defocus’ autofocus system which offers focus times as quick as 0.07 sec and less hunting, according to the company. Stills photographers also get an amazing 12 FPS burst rate. You can compose photos and videos on either a 3″ 1.04M dot fully articulating OLED display or an OLED EVF with over 2 million dots. Other highlights include Wi-Fi with NFC, as PC sync port, highlight and shadow control, and a ‘silent mode’ which uses the electronic shutter only.
The price is yet to be confirmed but the GH4K is likely to come in at under $2000. With these specs at that price Canon, Nikon and Blackmagic all have their work cut out.
