No Klaus but ...
the Samyang has (as mentioned in the review) an untypical projection.
Therefore it covers APS-C albeit it has "only" 8mm focal length.
Would you "shave" the hood, the image circle would be too big to be
a circular fisheye on fullframe ... to be a diagonal fisheye on APS-C it needs
an image circle of at least 28-29mm ... to be a circular fisheye on fullframe
it needs an imagecircle of no more than 24mm ... obviously it cannot be
both at the same time.
So if the hoods are removed, the circle would still be cut on top and bottom
of the frame (when used on fullframe).

Thanks Rainer, Photinius...
Should have realized that since it covered the full APSC frame the circular image wouldn't fit on FF. But as P says, it could still make a good lens for VR photographs on full frame...
