User:Berghei/Panasonic Lumix DMC-GH2

The Panasonic Lumix DMC-GH2 was released in October 2010 as a successor to the Panasonic Lumix DMC-GH1. Still using the Micro Four Thirds System, the GH2 improves upon the video recording capabilities of its predecessor and incorporates many upgrades such as a higher resolution sensor and a faster contrast detect autofocus system, owing to the new sensor redeveloped by Panasonic and first implemented in this model. The GH2 also 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.

Features
With the GH2, Panasonic strengthen their position gained with the one year older GH1 model, which was the first consumer-priced interchangeable lens camera to offer autofocus capability while shooting HD video. 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. When taking still photos, the GH2's AF performance is comparable to the phase-detect systems in competing digital single-lens reflex cameras (DSLRs). 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 camera has a dedicated video button and a stereo microphone, features not present on competing video-capable DSLRs. The GH2's electronic viewfinder has been widened compared to the GH1's, increasing the number of dots to 1.53 million from GH1's 1.44 million. The wider screen better accommodates the GH2's over-size multi-aspect ratio. This ensures that the user can take pictures in 3:2, 4:3 and 16:9 without significant cropping.

Owing to the Micro Four Thirds format, the lenses and camera body are smaller than competing 35 mm format DSLRs. Available lenses include a 14–45 mm ƒ/3.5–5.6 lens (28–90 mm equivalent), a 45–200 mm ƒ/4–5.6 lens (90–400 mm equiv.), a 14–140 mm ƒ4.0–5.8 (28–280 mm equiv.) and an 8 mm ƒ/3.5 fisheye lens with a 180° field of view. Lenses support optical image stabilization. With the GH2, Panasonic also introduced a 3D lens (LUMIX G 12.5mm / F12 (H-FT012).) Four Thirds System lenses can be used with a Micro Four Thirds adapter.

The camera is available in two colors &mdash; black (suffix K) and gray (S).
