The LUMIX GH1 also records video in high-quality stereo sound via Dolby Digital Stereo Creator, the global standard of audio recording.
Like the LUMIX G1, the LUMIX GH1 features the Live View Finder system which enables something that simply is not possible with conventional DSLR cameras ? the ability to preview the effects of camera settings (e.g., exposure, aperture, shutter speed) before taking the photo.
The 1,440,000-dot equivalent Live View Finder system can also display information settings that a user can see without removing their eyes from the subject. Furthermore, a built-in eye sensor automatically switches on the viewfinder when the user looks into it, then switches it off and turns on the 3.0-inch 460,000-dot high-resolution LCD when the user looks away from the viewfinder. The 60-frames-per-second Live View is made possible by the Live MOS sensor, which takes real-time signals directly from the image sensor and sends them continuously to the LCD. Both the Live View Finder and LCD provide a 100% field of view ? allowing the user to accurately frame and compose a shot from most any position.
At the core of the LUMIX GH1 lies a newly developed 12.1-megapixel high speed Live MOS sensor and Venus Engine HD, which features twin CPUs. The Live MOS sensor is capable of high-speed readout over four channels to be compatible with full-HD movie recording. This sensor is also advantageous for photo recording with a high signal-to-noise ratio thanks to the new circuit structure that is unaffected by the noise generated in each of the circuits. The multi-aspect type sensor allows users to take photos in 4:3, 3:2 or 16:9 aspect ratios with the same angle of view.
In addition to the digital camera?s HD video recording capability, the DMC-GH1 features the LUMIX Creative Movie mode which lets the user manually set the shutter speed and aperture, making their videos more creative and representative of their own personal video style preference.
The LUMIX GH1 is also incredibly easy-to-use, thanks to Panasonic?s iA (Intelligent Auto) mode ? a user-friendly setting made popular in the LUMIX line of digital point-and-shoot camera products. Panasonic?s iA mode is a suite of technologies which engage automatically (no settings needed). The latest addition to the iA suite of features is Face Recognition, a feature that directs the camera to prioritize focus and exposure on a specific face that that the user had previously registered in the camera.
Best of all, the benefits of Panasonic?s iA mode extend to motion image recording on the DMC-GH1. For example, the LUMIX GH1 motion iA includes O.I.S. and Face Detection, which automatically detects a face in the frame and adjusts focus, exposure, contrast, and skin complexion. Intelligent Exposure continually checks the ambient light level and adjusts the exposure setting as conditions change to prevent blown highlights and blocked shadows. Intelligent Scene Selector automatically switches between Normal, Portrait, Close-up, Scenery, and Low Light modes according to the environment. The Contrast AF system adopted by the LUMIX GH1 aloows users to choose from a wide range of AF modes, including multiple-area AF with up to 23 focus areas, 1-area AF with a selectable focus area, Face Detection, and AF Tracking. To help keep the images free of spots from dust and particles, the Supersonic Wave Filter dust reduction system helps prevent foreign contaminants from adhering to the image sensor.
