Reviews Word on the street for the Panasonic Lumix DMC-GH4

What People Are Saying Give it to me straight

Video

It's the first prosumer model to offer Cinema 4K (C4K, 4,096x2,160) in addition to Quad HD 4K (QHD, 3,840x2,160), and notably it supports potentially extra-high-quality HD, meaning 4:2:2 10-bit output with a 200Mbps bit rate at all the major frame rates.

In conjunction with the latest iteration of its Venus Engine image-processing chip, Panasonic claims a wider dyamic range and decreased rolling shutter.
by c|net (Feb, 2014)
Too fast, in fact, for video, where you don't want it to snap from one subject to another; you want it to glide gracefully between subjects.
by c|net (Feb, 2014)

Focus

While it uses the same metering system as earlier models like the GX7, the GH4 debuts a new autofocus system, a combination of traditional contrast AF and DFD, or Depth from Defocus.
by c|net (Feb, 2014)
In theory, when the camera knows the characteristics of the lens and the deviation-from-focus of two planes parallel to the focal plane, it can calculate the location of the in-focus area faster than it can iterate there using plain old contrast AF (the contrast AF system has been enhanced as well, though).
by c|net (Feb, 2014)
The GH3's successor, the Lumix DMC-GH4, packs a host of feature and technology enhancements in the old body that offers something for everyone: 4K video and a new autofocus system with improved continuous-shooting performance are just the highlights.

Lens

Speaking of accessories, Panasonic also announced a shotgun mic and support for some zoom mic features in the camera to go along with it.

The mode dial now locks; it has a larger, more comfortable eyecup on the viewfinder; and the EVF and LCD are higher-resolution, and Panasonic claims better color reproduction and less distortion for the EVF.

Controls

In-camera you can only record 4:2:0/8-bit video; to record 4:2:2/10-bit video you to need run it through the HDMI connector to an external recorder via the horribly named but practical Interface Unit (DMW-YAGH), a powered dock that addstwo XLR inputs with audio controls, SDI output, and various time-code options.
by c|net (Feb, 2014)
It remains to be seen if there are any controls over the focus speed for that.

Wifi

Lastly, the Wi-Fi connectivity now can use NFC and QR codes to more quickly pair devices.

In The News From around the web

There is no harsh highlight blown out in these images although the shadow is still a bit too dark, still not bad for m4/3..
I don't see anything at truly high ISO, which is really peculiar since there are always really high ISO shots to illustrate both sensor and jpeg engine performance.
