Autofocus Tips
Checking Focus
Position a ruler at an angle so that one of the rules is at the same distance from the camera as a vertical surface such as the cover of a book stood upright. Using autofocus, focus on the vertical surface and then photograph the selected rule using focus lock.
The illustration below shows how to interpret the results.
