Default Sigma says in-lens stabilization compromises optical performance

And they'd be right. It has to. Shifting a lens or lens group
laterally obviously changes the correction of the system. One more
reason in-body is better.

Any IS will... IBIS alters the optical system in camera and there is a
lag between motion in lense and sensor. Just as there is a lag in ILIS
of the same kind. And both system compromises the optical path...
