The DMC-GH2 boasts its high performance to make the photographic experience even more comfortable and fun. It features the world's fastest level light speed AF which is achieved by reducing the detection time for focusing by doubling the drive speed from 60 frames per second to 120 frames per second. Not only the accuracy but also the speed excels by far than the high-end DSLRs with phase difference AF with the advanced contrast AF system in the DMC-GH2. Combined with the touch AF control, setting and focusing at the subject is incredibly easy and quick, never missing the spur-of-the-moment.Panasonic also refined its comprehensive digital imaging technologies for every camera of Lumix G micro system to raise the level of image quality that rivals or even surpasses D-SLR cameras. The developed 16.05-megapixel multi-aspect live MOS sensor adopts the high speed digital ?Maicovicon. In addition to the high speed, which is an advantage of the CMOS sensor, Panasonic adds its original pixel mix technology. A dedicated process exclusively for ?Maicovicon of the DMC-GH2 is developed by applying the top-class high performance transistor and its interconnection process needed for the high speed operation of digital circuit to make low-noise photodiode and transistor with reduced wiring to achieve both high resolution and high aperture-ratio as the DMC-GH1.
