Kenko 1.4x Teleplus Pro 300 DGX for Nikon

KENKO Teleplus Pro 300 converters are made with precision quality multicoated optical glass supplied by Hoya Corporation the worlds largest manufacturer of optical glass. These glass elements are designed to match the optical quality of the prime and telephoto zoom lenses (even at the edges). The optical design of the elements and light path is wide enough not to cause vignetting. Kenko's Teleplus DGX teleconverters are available in Canon and Nikon fittings. When using a DGX converter with a digital SLR camera the converter automatically determines the resulting focal length and aperture of the combination and records this in the image file's EXIF data.
