Add the 1.6X Tele-Converter to the front of your lens to shift its focal range in the telephoto direction. The perfect tool when it's inconvenient, dangerous, or even impossible to move as close to the subject as you'd like. The 1.6X Tele-Converter alters your zoom's focal length range from 4.5 - 54mm to 43 - 86.4mm - with no appreciable light loss. Note vignetting occurs when zoomed to the wider angles. The Tele-Converter is specially effective in "run-and-gun" shooting situations because it attaches quickly to the front of the existing lens with Century's popular bayonet mount. For greater protection, the face of the unit offers 102mm threads for an optional UV filter. For use with the Sony HVR-Z1U and HDR-FX1.
