The Panasonic Lumix DMC-GH3 is a digital mirrorless interchangeable lens camera (MILC) manufactured by Panasonic. It is the successor to the Panasonic Lumix DMC-GH2 and was announced in September 2012 at photokina. It was available from November 2012.〔(Lumix GH3 – Neues DSLM Top-Modell mit professionellen Features ), Press release, Panasonic, 17 September 2012〕 It is the first MILC that can record videos with a bit rate of up to 72 megabits per second. That is significantly higher than the specification of AVCHD 2.0 of up to 28 megabits per second, which was released in July 2011 and is used for similar cameras and camcorders.〔(AVCHD Format Co-Promoters started licensing the AVCHD Format Version 2.0 ), AVCHD Information Website, online 17th September 2012〕 The successor of Panasonic GH3 is Panasonic GH4 with capability to take 4K video, with MSRP about $1,700, but the optional external video/audio unit cost $2,000.〔(【引用サイトリンク】title=Panasonic's 4K-ready Lumix GH4 priced at $1,700, ships in late April )〕 == Technical specification == The camera body is made of a magnesium alloy and has a swivelable touch screen, an electronic viewfinder with diopter correction, an internal flash light and a hot shoe. Due to the short flange focal distance of about 20 millimeters for the Micro Four Thirds system, almost all lenses with an appropriate image circle can be mounted to the body with a lens adapter.〔(Objektivadapter für Micro-Four-Thirds-Kameras – Zahllose Objektive können an die neuen Kameras angeschlossen werden ) ], golem.de 6 August 2009, online 17th September 2012〕〔(Adapter für Micro-Four-Thirds – Die Welt der Fremdobjektive ), Forum Four Thirds, online 17th September 2012〕 The normal focal length is at about 25 millimetres. In all still and movie modes as well as with the monitor or the electronic viewfinder, the GH3 works in live view mode. It can be operated in manual focus mode with software magnification or with a versatile contrast-detection auto focus system, including face detection and object tracking. This applies to steady shots as well as to movie takes. Due to the optional electronic shutter the camera can take images without any acoustic noise.〔(DMC-GH3 - Lumix G DSLM Wechselobjektiv-Kamera ), www.panasonic.de, overview, online 17th September 2012〕 The camera body has a lithium-ion battery, and an addition battery grip can be attached, which has a release button for portrait shooting, along with other control elements. The GH3 has an internal stereo microphone and a socket for external microphones. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Panasonic Lumix DMC-GH3」の詳細全文を読む スポンサード リンク
