When you're shooting for a truly exaggerated point of view, twist on the Pro DV Series .3X Ultra Fisheye Adapter. The Fisheye gets you the widest view possible, with extreme barrel distortion. This non-zoom-thru add-on provides approximately 1.3mm focal length, 130° horizontal angle of view. Please note that vignetting will occur at the extreme wide angle. The fisheye exaggerates depth, pulling nearby objects closer, and causing distant objects to recede into the background. A fixed adapter, the Fisheye doesn't allow for zooming - but you'll want to stay at the wide end of the range anyway, for the most pronounced effect. Uses Century's popular Bayonet Mount that attaches with a twist to the front of the lens. For use with the Sony HVR-Z1U and HDR-FX1.
