It's not really sharpness - you get weird artifacts since it's combining multiple (slightly different) captures to create one big one. Some other cameras reportedly have better merging algorithms that make them more capable of handling motion in the scene but I haven't tried those. It really is kind of a gimmick feature unless you have very specific locked down scenes, like a still life.
