Our sample film, recorded using the GH4, at Dungeness
The GH4 is based around a single Panasonic 16.05 MOS sensor, with a Beyer pattern filter. As a Micro Four Thirds camera, this sensor equates to a 1.33-inch chip, a 2x crop compared with a full-frame sensor.
Although it is a mirrorless system, the GH4 follows a conventional DSLR layout, with a hand grip to the front, control knobs on the top and a range of dedicated and assignable function buttons, an LCD screen on the rear, and a viewfinder – in this case an EVF.
The lens mount is Micro Four Thirds, a system developed jointly by Panasonic and Olympus, but which is also supported by a range of other manufacturers including Sigma and JVC.
In most respects, the GH4 follows the convention for stills-based cameras for inputs and outputs too, including 3.5mm jacks for audio in and out and HDMI for video out, rather than XLR or SDI connections – but the camera can be expanded with the YAGH adapter, of which more below.
