The problem is that the autofocus can not adjust correctly. There can be more than one solution.
-
1. Try forcing the lens to rotate a fraction of a inch. This will sometimes help the problem. Or simply move the switch from M to A on the lens.
-
2. Try to switching to a single of the 11 auto focus points. Then try if there are specific points that are the problem.
-
This is done by selecting in the menu of your camera to the points. Then focusing on a single object with a background far away. Try focusing on the object then on the background. If this is possible the autofocus point is fine.
-
3. If all auto focus points are fine, try updating the firmware or cleaning the sensors inside the camera behind the mirror. If a one or more points are out of order, also try cleaning the sensors behind the mirror.
-
4. Detatch the lens from the camera, by applying pressure on the release button and twisting the lens so it can be released. See picture
-
5. Set the camera selection wheel to manual (M), see picture
-
6. Turn the camera on, and start the liveView format. This will flip op the mirror inside the camera.

-
Take a dry can blower. Or if in lack, use an empty plastic bottle, without moisture inside, and use it to blow on the autofocus sensors.
-
They are located at the bottom under the mirror. NOTE Do not blow with your mouth, small amount of moisture will hit the CCD also located here.
-
Turn the camera off
-
Reattach the lens. Push the lens, white point to white point and turn the lens in place.

This worked for me, hope it also helped you ;)

Yes!! Thank you so much. The center point of our autofocus wasn't working, and I was worried that the camera would need expensive repair. This did the trick instantly. You just made my day!
