smc FA 645 45-85mm f/4.5 Lens not autofocusing anymore


Yesterday I was out shooting and my FA 645 45-85mm f/4.5 lens stopped autofocusing for some reason. I didn't drop the lens or anything like that. I know the problem isn't with the camera itself, as my other lenses' auto focus system works just fine on the same body. I also checked if the ring was set to "A" and it was.

Does someone have any tips or suggestions about what I could do to solve this problem ... aside from sending it away to get repaired (it's no longer under warranty).

The focusing ring could accidentally have been pulled back to the manual focus position. It must be pushed forward so that the words Auto Focus show.

Thanks, Ole. Problem solved. I guess it shows I'm new to the Pentax system!
