Focus where you want when shooting Macro

Often when doing macro photography, the auto focus system does not always focus where you want the focus to be. We all know that in macro work, the Depth of Field (DoF) is a thin sliver and focus needs to be exact to achieve what we want.

Here's a hint that may save some frustration:
Let the AF choose a focus, then you lock the focus, or switch lens to manual focus. Now you can slowly move yourself and the camera closer to, or farther away from the subject and choose exactly the portion you want to have in focus. I will often leave the lens in manual focus, so I can get close to what I want by focusing the lens, then get the precise point by slight movements of my upper body.
