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