The 2X HR Tele-Converter is a front-mounting accessory that provides greater telephoto reach without light loss. Available in popular 37mm screw mount, the 2X HR Tele-Converter instantly shifts the focal length range in the telephoto direction. The Century 2X offers front threads for convenient attachment of 62mm filters.
Note: Vignetting will occur in wide angle ranges producing a porthole effect which is common with all tele-converters.
