The Panasonic Lumix DMC-GH4: The Unofficial Quintessential Guide provides a wealth of information and professional insights for owners of this powerful HD camera. With its electronic viewfinder and interchangeable lenses, the GH4 is capable of not only recording professional-quality still images, but has the added ability to record HD video as well. The mirrorless design enhances the camera's versatility beyond that of most digital single lens reflex (DSLR) cameras. With the appropriate adapters, it can use virtually any manufacturer's manual focus, legacy lens. It is smaller than a typical DSLR in both size and weight, and retains automatic focusing while recording videos-a capability that is missing in many DSLR cameras. With the GH4, Panasonic has significantly expanded the video capabilities beyond those of previous models. Among the improvements is the camera's ability to record 4K video and save the movie to the internal memory card. Along with these powerful functions comes complexity, and that is where this essential guide comes in. Authors Brian Matsumoto and Carol Roullard explore and explain the features and capabilities of the GH4 in detail, as they cover everything from the basic features of the camera to numerous advanced photographic applications. The informative text is illustrated with example images throughout. von Matsumoto, Brian und Roullard, Carol F.
