I dial in the autofocus on all my lenses. It's fairly simple and well worth the effort. You can find instructions and targets for doing it online.
With that 16-50/2.8 you should also check to make sure the focus field is flat. You can do that by shooting a brick wall off a tripod at f 2.8. with each side of the frame equidistant from the center of the lens. If one side of the frame is sharper than the other side, you have a lens with a manufacturing defect. Quite a few of those were produced and sold when the lens was first released. Later production is okay.
