Due to the much smaller minimum focus distance, I can take pictures like this. For this image, I wanted to make sure that the focus was perfect. To ensure that I switch from autofocus to manual focus. Most of the time I prefer autofocus because it allows me to take pictures quicker and is one less thing to focus on. But, during dark conditions (night time long-exposures) or when I am trying to focus on an object (such as this picture), I will switch to manual focus.
