The Century Optics 1.6x HD Telephoto Conversion Lens can be added front of your lens to shift its focal range in the telephoto direction. The 1.6x Tele-Converter alters your zoom's focal length range with no appreciable light loss. Note that the Tele-Converter offers partial zooming, vignetting will occur at just past mid-range through full wide angle. At full wide angle you will have a port hole effect.
The Tele-Converter attaches quickly to the front of the existing camera lens with the popular built in bayonet mount lock ring. For greater protection, the face of the unit offers 102mm threads for direct attachment of Schneider 102mm clear UV (68-120021) and polarizing (68-013002) filters.
