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.
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.
