Thank you for contacting JustAnswer.

Please inform:

I have tried with two lenses.

 

The problem is with the EF 28-90mm lens and not with the EF 75-300mm

 

Thanks

Thank you for your quick answer.

The problem is not with the camera.
I assume you have the 28-90 Canon EF. There is a MF/AF switch. It should be in the AF position. If that's where it is, the problem is with the lens. Try to wiggle the switch back and forth a few times and try to auto-focus again. If still does not the work, I am afraid the lens may need servicing or replacing if it still under warranty.

Hi,

 

Before you send the lens away for repair, try cleaning the contacts on the lens and camera body with an eraser. Just a little dust or residue can hamper the connection between the camera and the lens.

I agree with Russel. Just follow the advise in case there is "a little dust or residue" between the contacts of the lens and the camera.
