The Century Optics .75x HD Wide Angle Converter is the right tool for shooting situations that require both a wider angle of view and full zoom capability. The converter increases the field of view by 25%. This professional add-on lens produces crisp, high resolution images with low distortion, and superior contrast edge-to-edge. Interfaces directly to the bayonet mount on the front of the lens for quick and easy mounting & removal. For greater protection, the face of the unit offers 102mm threads for direct attachment of 102mm Clear Filter or 102mm Linear True-Pol (both sold separately).
