(From company literature) Placed between the camera body and lens, a teleconverter contains a set of optics that will effectively increase the focal length of any lens with which it is used. The KENKO TelePlus MC4 AF 2.0X DGX converter has the effect of multiplying the focal length of your lens by 2.0x, turning a 300mm lens into an equivalent 600mm lens.

The MC4 AF 2.0X DGX converter has genuine Gate Array IC (Integrated Circuitry). It means the converters unique circuitry maintains signal integrity between the camera body and lens. The 4-element design is made with high quality multi-coated optical glass supplied by Hoya Corporation, the worlds largest manufacturer of optical glass.

MC4 AF 2.0X DGX are available for Canon EOS (EF, not EF-S) and Nikon AF.
