FS 700 Metabones adapter Rokinon 8mm Compatibility

[Girlspitswater]

I would like to know of if you think the combination of the Sony FS700 camera, Metabones EF to NEX adapter, and the Rokinon 8mm Cina Lens would create vignetting artifact on the lens. Have you heard of anyone using this lens/camera combo with your product without getting a vignette artifact around the perimeter of the image?

I've seen this test online of a Canon 8mm fisheye giving a vignette artifact, curious if it would do that same with the Rokinon 8mm cina lens:

Thanks, much appreciated.

With the "normal" Metabones EF > E-mount adapter and the Rokinon 8mm fisheye, there's no vignetting (with or without the petal hood attached).

With the Speedbooster EF > E the lens produces a circular image enclosed within the frame (with the hood removed...it's shaped more oddly with the hood attached).
