My D80 just started acting up - the lens makes funny gear noise and is unable to auto focus on a stationary subject for some reason. I can manual focus fine. I have reset the camera and tried other settings but it still occurs.
Is it the lens or in the camera?
Any help in diagnosing the problem would be helpful. (it is the lens that came with the camera - the 18-135mm lens)

Hi, That lens is AF-S type so it really sounds like the lens has a mechanical issue. The camera focuses the lens electically. If the lens was silent it could go either way, but if the lens is noisey and not focusing it seems unlikely that it is the cameras fault. Of course if you have a friendly dealer, you could put another AF-S lens on and prove that to be the case.

I took my camera to a local camera store (Wolf Camera in this case) and explained my problem to the clerk. My camera seems to focus corectly 50% of the time and the lens makes more noise then before. After using it in the store he also agreed that there was something wrong with the lens.
I will be sending the camera back to Nikon USA for repair. Fortunately, I can use the lens from my N80 on the D80 while it is being repaired.
I hope this helps.
If more people are having problems with this defective lens, it could be a real problem for NIkon

I have had this same problem TWICE with an 18-135 on my D80. Ir wouldn't acquire focus under any situation and made a loud whining sound. Other lenses worked just fine under the same focusing conditions. On the first instance I took the camera/lens back to the seller and they replaced the complete kit. The next time it happened was with the new lens/camera about 3 months after purchase, and I sent the lens back to Nikon. It took about 3 weeks from the time I sent it to them to get it back, and the Repair Invoice stated that they replaced the "MR Encoder Unit". Thus far it works fine. Good luck with yours.

I am going to be very interested to see how long these repairs to the 18-135 last. For example, are they replacing the defective parts with the same type of parts that may fail again in the future, or ar the replacement parts more durable and free of defects????
