Schneider's Century .75X HD Wide Angle Converter is a newly designed, lighter weight optical tool for shooting situations that require both a wider angle of view & full zooming capabilities. The .75X HD Wide Angle Converter attaches to the front of the lens via the lens bayonet mount for 25% more coverage when set to wide angle, telephoto or anywhere in between. This new professional add-on lens produces crisp, high resolution images with low distortion and superior contrast edge to edge.
