A standard for a universal digital SLR system proposed by Olympus and Kodak in 2002. The Four Thirds system is based around the 4/3 CCD image sensor size, hence the unusual name. The idea behind it is to promote a line of interchangeable and compatible cameras and lenses from a variety of manufacturers. Thus far support for Four Thirds is rather limited. Olympus, Kodak, Fuji, Panasonic, Sanyo and Sigma have agreed to participate. Notably Canon, Konica Minolta, Nikon and Pentax have not.
cf. CCD, Kodak, Olympus.
