Rokinon 8mm Fisheye

Rent this super16 zoom lens for any PL mount camera with a Super16 sensor (or smaller!)  The Canon 7-63mm is one of the widest zoom lenses ever made in a PL mount for Super16 cameras.  With it, you should be able to skip renting a wide angle prime as you would with a standard 10-120mm ranged lens.  Not to mention Canon cine lenses are excellent across the board.
