Kenko Converter HD DGX MC 1.4X Nikon AF

The Kenko Converter HD DGX MC 1.4x Nikon AF contains a set of optics that multiplies the focal length of your prime lens by 1.4x and converts a 300 mm lens into an equivalent of 420 mm. HD DGX Converters Use unique circuits that maintain signal integrity between camera casing and lens. It also enables accurate recording of digital EXIF data. Multi-coated optical glass is used in optics, which is provided by Hoya Corporation, the world's largest manufacturer of optical glass. Full AF control with the HD DGX 1.4 x is possible using a camera lens with an open aperture of F4 or brighter. Keep in mind that the AF only works well if there is sufficient light and contrast on the subject to correctly activate the camera's AF sensors, otherwise manual focus may be necessary.
