The 2X Tele-Converter is a front-mounting accessory that provides greater telephoto reach. It instantly shifts the focal length range in the telephoto direction Available in popular bayonet and 58mm screw mount, the 2X Tele-Converter instantly shifts the focal length range in the telephoto direction.
Unlike typical rear-mounted telephoto extenders, the Century Tele Converter provides doubling of the indicated focal length (through the higher end of the zoom range) without light loss, along with front-mounting convenience.
