I just went outside and tried this because I didn't think it made much sense. I was right. It didn't make much sense. The halo does get much bigger when you focus closer but it also expands when you focus further away. My new theory is that you should focus closer because it will go out of focus more quickly and more completely because the DOF narrows in that direction.
Maybe it's got something to do with rendering of the famous bokeh... Jostein
