gH1

GH1 is the Panasonic Lumix DMC-GH1, a mirrorless interchangeable-lens camera released in 2009 as the first model in the Lumix GH line and the first Micro Four Thirds system camera from Panasonic, developed in collaboration with Olympus. It marked a shift toward hybrid cameras that could capture high-definition video alongside still photographs, using the Micro Four Thirds lens mount for compact interchangeable lenses.

The camera uses a 12.1-megapixel Live MOS sensor paired with the Venus Engine HD image processor. It records still images with typical sensitivity for its generation, and it provides features common to advanced prosumer cameras of the era, such as live-view shooting, interchangeable lenses, and manual exposure controls in both photo and video modes. Storage is via SD/SDHC cards. The GH1 includes a 3.0-inch LCD for composition and, in addition, supported an optional electronic viewfinder through an external accessory.

Video capabilities are a standout aspect: the GH1 records HD video using AVCHD Lite, enabling full high-definition capture in a compact body, a pioneering feature for a Micro Four Thirds camera at the time. The body also supports various video options and settings intended for film and documentary work, appealing to videographers as well as photographers.

Release and reception: The GH1 was generally well received for its hybrid design, image quality, and expanded video features, but it faced criticism for noise performance at higher ISO and for some early limitations in autofocus speed. It laid the groundwork for Panasonic’s subsequent GH models, including the GH2, and contributed to the growth of the Micro Four Thirds ecosystem.
