An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is displayed on a small screen (usually LCD or OLED) which the photographer can look through when composing their shot. [1] It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power.
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.
The display moves around two axes which are at a right angle to each other, so that the screen both tilts and swivels. This type is called swivel screen . Other names for this type are vari-angle screen , fully articulated screen , fully articulating screen , rotating screen , multi-angle screen , variable angle screen , flip-out-and-twist ...
Live preview on LCD. The concept for cameras with live preview largely derives from electronic TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.
There is a half mirror prism that reflect data from LCD to the optical viewfinder, so we can see both the shooting frame and the shooting data. A button can change the hybrid function to electronical viewfinder by blocking the image through the optical viewfinder with moving a half mirror prism to be a straight up mirror. [5]

Physically, the G3 approximates the size of the small Panasonic Lumix DMC-GF2, but includes an electronic viewfinder (EVF) and an articulated, touch control-enabled LCD panel. This made the G3, upon its introduction, the smallest available MFT camera with a built-in EVF, 25% smaller than the G2.
