18-200 vr lens auto focus quit

Mon 04-Jun-07 02:33 AM
I love my Nikon D200 and my Nikon 18-200mm AF-S DX VR Zoom lens. I recently noticed that if I am pointing the lens towards the ground, the front flange of the lens slowly extends outward as though I am zooming (As long as I am not holding onto the zoom ring). I'm hoping that the zoom ring tension can be stiffened to prevent this from occurring.

My newest problem caused me to quote Scooby Doo by saying, "Rut Row". Two days ago, I was attempting to take a picture of a nearby object when the lens wouldn't lock-on. The lens would focus, then immediatley go back out of focus for no apparent reason. This happened over and over, so I switched to manual focus and took the shot. I did not have time to trouble shoot the problem any further at that time. Yesterday, I attempted to take a photograph with the same lens (VR on) when I heard a squealing noise coming from the lens as it was attempting to focus. The lens did not focus. I turned VR to off position, but still the lens would not focus. It just made a slight click when the shutter release was pressed. The lens does not even attempt to focus at this time.

To trouble shoot the problem, I changed lenses from the 18-200mm, to my Nikon 105mm AF-S VR Micro lens. To my relief, the 105mm lens was quick to focus and worked flawlessly. I then switched back to the 18-200mm lens and found the auto focus was still dead-in-the-water.

Time for my first experience with Nikon repair service. Has anyone else experienced this problem, and is there hope for a permanent fix?

By the way, I have never dropped or banged my lens or camera, and I have not exposed them to moisture.
