The Panasonic 0.75x Wide Angle Lens Conversion allows you to extend your shot framing by 0.75x. This means you can get more people in the frame without having to move farther back. This model fits on the V700 and X900 camcorders. The converter is a zoom through, which means that it will hold focus throughout the zoom range, it features a 46mm filter thread for mounting on your camera's lens and includes a 46 to 49mm step-up ring.
