The Panasonic DMC-GH1 Digital Camera merges the very best of digital SLR technologies with advanced, next-generation HD video recording. Utilizing the Micro Four Thirds system, the camera design offers a 50% shorter flange spacing (mount-to-sensor distance), and a 6mm reduction in the size of the outer lens mount. This innovative, mirror-less design dramatically reduces the size and weight of the camera body and allows for the development of more compact optics.
