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).

Yes, and that is the reason why the Peleng has black corners. It's a full frame circular fish-eye, so with it's 24mm
it does not cover the APS-C diagonal.
People do use the Samyang shaved for panoramas, see the links herein:
