Hmmm. Put optical image stabilization in a lens to reduce shutter speed by
two EV. But put in twice as many optical elements, thereby boosting the
lens's weight by how much? And that extra weight requires boosting the
shutter speed back up by how much?
What's wrong with this picture?
More weight means more inertia. More inertia means a slower possible shutter
speed, not a faster required one.
