  1. Get a ruler and put it on the table.
  2. Choose a target line on the ruler to focus on.
  3. Set your camera on a tripod and point at the ruler at 45 degrees angle.
  4. The camera should be far enough from the ruler to be able to auto focus.
  5. Use the widest aperture (smallest F-number).
  6. There should be a good even light and proper exposure.
  7. Use S-AF/One Shot Single Point focusing mode.
  8. Make sure that your center focus point is set directly on the target line.
  9. Take a picture using auto focus. See if your target is in focus. Try a few time.
