I have a Nikkor AF-S DX VR 18-200mm and I have a problem with the focus ring. It goes fine from infinity to about 0.9m, then it just stops there and I can't go down to 0.5m no matter how much I turn the ring. Autofocus can't go lower either. This happens at all focal lengths. Is there something I can do about this myself or do I have to send it Nikon for a repair and hope that it doesn't cost more than a new one?

I bought the lens used about two years ago and I have only used the autofocus before, but now I need to use manual focus for the first time (more or less only use the camera on holidays) and then noticed that it stuck on 0.9m.

I should mention that the focus works fine in the range that I can turn it to.

  • Does this hold true at all focal lengths? 18mm, 50mm, 85mm, 100mm, etc. all the way up to 200mm? – Michael C Jul 1 '15 at 0:16
  • Yes, the problem persist for all focal lengths. – SpaceOgre Jul 1 '15 at 5:25
  • Did it work ok before? and can it autofocus below 0.9m? – Digital Lightcraft Jul 1 '15 at 13:27
  • No autofocus can't get below 0.9m either. To be honest I'm not sure if it has worked before, I bought the lens used about 2 years ago and I have only used the autofocus befor but now I needed to use the manual for the first time (more or less only use the camera on holidays atm) and then noticed that it stuck on 0.9m – SpaceOgre Jul 1 '15 at 13:45
  • While the marks says "0,9m", what is the actual focusing distance? I'd bet on that that index plate is misaligned. – Euri Pinhollow Apr 12 '16 at 16:21

The most likely answer is that the lens has been damaged. I had a Nikkor lens (75-300/4.5-5.6) that had this same problem at one point. I sent it in for repair and Nikon advised that the lens had impact damage. It had most likely been dropped or fell onto a hard surface, which damaged the focusing helicoids.

The only way to know for sure would be to disassemble your lens (risky) or to send it away for service (costly).

Note that if the theory is right, you may not be getting optimum sharpness from the lens, either, as elements have possibly shifted slightly due to the impact.

  • This could very well be the case, I have not noticed a problem with sharpness but since I bought it used it is hard to tell since I don't have anything to compare to. ATM it is working good enough so until it breaks down more I will use it as is. – SpaceOgre Jul 25 '18 at 7:00
  • @SpaceOgre It's possible that only the focus helicoids were affected by the suspected impact, so you could be lucky and the glass could be perfectly fine. – Jim MacKenzie Jul 25 '18 at 14:37
