So that the Community can help you better, please tell us the model name of your camera as it appears on the front and/or top of the unit. This will help the community to more readily identify which camera you're using and to help you accordingly. Any additional information you can provide about your focusing problem will also be helpful!
If this is a time-sensitive matter and you're in the United States, our US-based technical support team is standing by ready to help 24/7 via email at http://Canon.us/SupportCF or by phone at 1-800-OK-CANON (1-800-652-2666) weekdays between 8 AM and midnight ET (5 AM to 9 PM PT), and Saturdays from 10 AM to 8 PM ET (7 AM to 5 PM PT). We also encourage you to check out our Knowledge Base at that same link for answers to common questions.
If you're outside the US, please visit http://global.canon and choose your part of the world from the map to find the Canon group that serves you.
Thanks and have a great day!
