The lens is particularly designed for exclusive use with SONY HDR-FX1 High Vision Camera. It opens up the field of view ultra wide angle like 180 degrees (diagonal) and 138 degrees (horizontal), upon mounting the lens on the camera's lens. Further, the lens has an amazing resolution power of 625 lines/mm at center (MTF 30%) to suit the high vision image quality of the camera.
Note: The lens is designed to perform an optimum capacity when used at the zoom range from the widest angle point to 3.3X ratio. Beyond the 3.3X toward telephoto, it starts losing the image quality at corners.
