Focus Manual focus: Turn the focus ring on the lens to adjust the focus. The camera offers several focus assistance functions to help you focus more accurately when using the manual focus.
Face Detection You can use face detection with one of the autofocus functions to let the camera focus on the main subject automatically (Face AF). You can also combine face detection with the focus guide to help you focus on the main subject manually.
Formatting a Memory Card If the same error message is displayed even when you have inserted a formatted memory card facing the correct way, contact a Canon Customer Support Help Desk.
