It's amazing what a tripod, or a bean bag, or even brazing the lens
against a tree can do for sharpness.

it's even more amazing what optical stabilization can do, thereby
eliminating the need to carry a tripod or a bean bag, which may be
prohibited in many situations, such as museums, public streets and
parks, theaters and tsa checkpoints.

it's also amazing what a little (ok, a lot of) math can do after the
photo was taken, especially when a depth map was captured.
