Some random thoughts:

Did you try this in Auto mode and see if the lens can focus?

Are you sure the lens is locked into place?

Dirty contacts?

Did you try taking the lens into a store that has a t4i(650) on display and swap the lens?

It's of course possible the autofocus mechanism is broken or maybe the mf/af switch.

Did you try to move the mf/af switch a few times to make sure it was locked into the correct position?

Yes i've also used in auto mode,and tried to switch many times.Also tried to reinstall lens.Nothing helped.For the moment AF is working,but problem will repeating.That why i want to know the base of problem.If it is not working is it hardware problem or i just need to change firmware version?

First you have to determine if it's a lens or camera issue. That is why it is important that you first try another lens on the camera. If another lens works correctly, then the original lens is defective.
