Quote:That manager was a little stupid. Technically IBIS does introduce a little unevenness to vignetting but in practical terms that's irrelevant. ILIS does introduce resolution variations and, worse than that, inferior centering which nobody cared about either so far.
Re: ILIS:
All things being equal, it increases design complexity and cost. Due to additional technology (gyros, etc.) reliability is reduced and size/weight is increased.
IBIS makes much more sense except for long focals.
