Manual focus. Autofocus cameras don't have the focusing aids you use to find in manual focus cameras, but it's not that hard. Unless you're dealing with movement, you should be able to focus quickly enough by hand and get good results.
You can also try an old wedding photographer's trick: prefocus and set up for a good exposure at a certain distance (e.g. 10 feet) and then physically move yourself forward or back until your subject is that distance (e.g. 10 feet). That way you don't have to refocus or redo your exposure settings.
