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 degree horizontal angle of view. Note 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.
Comes in our popular Bayonet Mount that attaches with a twist to the front of the lens.
