Creating a fisheye effect with your lens, the Century Precision Optics 0HD-FESU-72 Extreme Fisheye HD is for lenses with a 72mm front filter thread. It creates a wide field of view with exaggerated barrel distortion without vignetting. The adapter does allow for partial zoom; however, to maximize the fisheye distortion it is recommended to keep your lens at its widest. The adapter allows you to zoom from wide to about mid-range with the camera in auto focus mode.
