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 popular Bayonet Mount that attaches with a twist to the front of the lens.
