Summary: The Panasonic GH4 performs exceptionally well as a flagship Micro Four Thirds camera. It brings 4K video to the masses, yet still offers the ability to extend the video recording capabilities for professional when combined with the DMW-YAGH interface unit. The GH4 has plenty to offer enthusiasts and pros who need a dual threat camera.
Excerpt: Panasonic takes their flagship GH camera to the next level with the new Panasonic GH4. As one might expect, given the sneak-peek of its prototype shown at CES this year , the "4" in the name will surely come to represent "4K." The Panasonic GH4 is the world's first mirrorless camera with 4K video recording capabilities.
Summary: Panasonic GH4 review: the GH4 offers some incredible features, like 4k video recording, focus peaking, a hi-res EVF and a vari-angle touchscreen. Find out how it performs in our review video. Panasonic has clearly invested a lot of time and effort in improving on the GH3 for the GH4, and the new range-topping camera has an extensive list of new or enhanced features.
Summary: Despite increased competition, the GH4 remains the most complete stills/video camera on the market. It's a competitive stills camera in its own right but the attention to detail when it comes to the provision of movie-shooting tools and capabilities makes it a stand-out camera.
Pros: Solid, comfortable-to-use camera body, Excellent still image quality, Industry-leading video capabilities, Highly detailed video capture, Extensive support tools - focus peaking, synchro scan, zebra..., 'DFD' system improves continuous focus ability, Good viewfinder and rear screen, Well thought-out touchscreen interface, Good battery life, In-camera Raw conversion and Wi-Fi, Optional accessory adds industry-standard connections
Cons: DFD system limited to Panasonic lenses, Focus tracking poor at subject identification, Focus peaking often too subtle to assess focus point, No Auto ISO in manual exposure video shooting mode, No option to cqpture 1080 video from 4K crop region to minimize aliasing, Wi-Fi can be awkward to set up
Summary: The Lumix GH4 probably could have turned up just with 4K video and still gotten people talking, so it's to Panasonic's credit that a clear and conscious effort has been made to create a camera with more to it than that.

Summary: The Lumix DMC-GH4 is a great overall unit that we enjoyed using, primarily because of its build quality and performance. It’s a top model to consider if you’re looking for a new high-end shooter with advanced hybrid (stills and video) abilities.
Pros: Great build quality and user comfort, High calibre stills and video capturing, Packed with features
Cons: Can take a while to get used to all its buttons and settings, but that's the case with all high-end cameras
Conclusion: Without its exceptional video functionality, this CSC would have received the same four-star rating as the GH3, because as fantastic as it is, it's fairly expensive. For a little more money you could buy a full-frame DSLR with a premium lens, which, according to DxO labs, will give you slightly better all-round image quality, and offer a shallower depth-of-field at like-for-like apertures.
Summary: Panasonic's Lumix creators are keen to appeal to professionals as well as enthusiast image-makers with this camera, so with those aims in mind they've developed a camera that really tries to do it all. The GH4 carries a host of pro-level video features and can capture stunning images with good detail and tone. The GH series has been a big hit with videographers especially, but now Panasonic has created a camera that photographers will be wise to pay attention to as well.
