Not at all.
CoC is noramally defined as the acceptable "unsharpness", still

the image was made. However, this acceptable level of unsharpness
is often
defined differently for different formats.
But this was not the subject.
The subject was which lenses (focal lengths) will record which images.
Bringing CoC in to the discussion is not helping anybody to
undserstand the
basic fact, that the same lens produces basically the same images,
regardless of the camera or sensor used. How you an I may assess
the final
results is not relevant to the subject. CoC is a relativ term
designed to
establish a commonly accepted measure for acceptable unsharpness.
It's an
agreement in the photographic industry. Not a scientific property
of optics.
Correct, Jens.
