Abakus B4 to JVC adapter
This high quality optics allows B4 mount lenses to be used on the JVC GY-HD series or similar cameras with 1/3", 3-chip detectors. The adapter does not change the focal length of the lens, but compensates for the different glass blocks in the 1/3" camera compared to the 2/3" cameras. This is essential to achieve high definition quality.
