The Panasonic Lumix DMC-GH2 is a digital camera with HD video recording capability that is part of the Micro Four Thirds System. Though commonly referred to as a DSLR (digital single-lens reflex) camera, it has no mirror or optical viewfinder, but has instead both a fold-out LCD screen and a (somewhat higher resolution) electronic viewfinder. Recording is to a SDHC or SDXC flash memory card in AVCHD or M-JPEG format, giving up to high quality HD 1080P video at 24fps with up to 2 hours per take on the USA or Canadian versions (for the European version it's 30 minutes per take maximum due to a European tax on video cameras). The GH2 is also notable for offering 1080/50i and 60i (interlaced) recording modes (compatible with broadcasting) as well as 24p, though 25p and 30p are not supported. The Micro Four Thirds System (crop factor 2 when compared to 35 mm still) does not offer the extreme shallow-focus effects possible with full-frame cameras. Optical image stabilisation is available on Panasonic MFT zoom lenses, and power zoom and power focus is available on some Panasonic X series lenses.
The GH2 was released in October 2010 as a successor to the Panasonic Lumix DMC-GH1. The GH2 comes with a touch-screen display, a feature that was not present in the GH1. Micro Four Thirds has the same sensor size as the Four Thirds System but replaces the complex optical path needed for the optical viewfinder with an electronic viewfinder displaying a live view; this allows for smaller and lighter lenses and bodies. Like the GH1, the electronic viewfinder (EVF) in the GH2 uses a sophisticated projection system to achieve a clearer, smoother display than that of compact camera EVFs. As with the GH1, it lacks a separate autofocus (AF) sensor; the GH2 uses contrast-detect autofocus using the readout from the main sensor. HD video mode also uses this purpose-designed contrast-detect AF system. Just like the GH1, the GH2 supports continuous autofocusing while shooting video.
The Micro Four Thirds sensor has about a quarter the area of a 35 mm stills frame, giving a crop factor of about two, so that a "standard lens" may be regarded as around 25 mm focal length. While the sensor is the same size as the Four Thirds system, the flange to sensor distance is much shorter, which as well as allowing small camera size, means that a great variety of camera lenses can be used with an appropriate adapter. In practice, the electronic focus, aperture control, and image stabilising may not work on an adapted lens, so use of an adapted lens is best considered on a case by case basis.
