Be sure that you're using a battery that can still accept a full charge. A lens's autofocus motor draws its power from the camera's battery; so if the latter is weak, it could cause a problem.

Does it focus in Live View mode?

Hey, 

I have the same problem as the guy who asked the question in this thread, my autofocus is not working. The autofocus motor just keeps spinning but without result. Although i noticed that in live view mode the autofocus works much better as you asked in this reply. Do you know how I can fix it? 

Thanks, 

Frank

I am sure you tried but do these steps anyway.  T3i in Auto mode, the green square.  Auto ISO.  Fully charged battery from a know good battery charger.  Set the lens switch AF/MF to AF.  Bright day shoot at something with vertical lines like a tree or fence post.

 

 Does it work now?  Smiley Happy

Hello Amastro, 

There are a few troubleshooting steps I'd like to help resolve this issue. We'll reset the camera, which should restore it to a default state. These steps should clear out the memory and thereby any errors which may be present.

- Anything attached or installed in the camera — memory cards, the lens, the battery, battery grips should all be removed.

- Once the lens is off let's check it using the steps below.

a) Clean the lens contacts* to restore connection with the body.

*Warning - Do not clean lens contacts on either a Canon lens or the camera body with an eraser! It's easy to rub off the gold plating on these contacts and end up with data communication problems! Our strong recommendation is to use a soft, clean, micro fiber cloth. Please do not use anything abrasive.

b) Try using a different Canon EF series lens. It doesn't have to be the same focal length as the one you were using.

c) If you are using a third party lens, we recommend discontinuing its use. There can sometimes be communication error related issues with third-party lenses. Ensuring that you're using a Canon lens eliminates that as a potential factor in the error.

If the issues seem to persist the next step would be to send the equipment to Canon for service.
