Panasonic Lumix DMC-GH4 sensor review: Heavyweight contenderBy Kevin Carter - Thursday April 10 2014 Sensor Review
Panasonic GH series of micro four-thirds cameras are some of the best all-round video and stills hybrid solutions currently available. Read on to find out how the new 4K capable Four Thirds sensor in GH4 performs.
As the successor to the popular and capable video-oriented Lumix DMC GH3 the new revamped model the GH4 adopts a similar 16-Mpix Live MOS sensor and familiar outer water-and-dust resistant magnesium alloy shell but it has several significant enhancements.
Both the EVF and rear swivel touchscreen LCD have been upgraded in resolution - the viewfinder, for example, up 614K dots from 1.7M to 2.36M, while a new more powerful quad-core Venus image processor has been employed to facilitate a new maximum 25,600 ISO setting and continuous shooting in Raw mode up to 12 fps (AF-S), 7 fps (AF-C), or up to 40 fps (without AF).
Like its predecessors, the GH4 also has expanded video-capture capabilities over other models in the range. The most significant and tempting features being in-camera 4K and Full HD capture with a range of resolutions, frame rates and high bit-rates. The 200 Mbps (All-I) high-bit rates refer to Full HD however, with 100 Mbps (IPB) being limited to 4K capture in a ‘cinematic’ 24p option at 4096 x 2160 or 3840 x 2160 at 30/24p. Curiously, both 4K modes have an option to record an 8.8-Mpix still during capture.
The GH4 can also be paired with an optional interface unit – a large battery grip like accessory that adds a raft of industry-standard ports that are simply too large to build into the relatively compact body of the camera. The Panasonic Lumix DMC-GH4 measures 5.2 x 3.7 x 3.3" / 132.9 x 93.4 x 83.9 mm and weighs 19.75 oz / 560 g. It is available for pre-order at $1,699 body only.
