I think my AF-S 18-200 Nikkor is dying. The zoom ring is stiff and jumpy, and the lens doesn’t seem to focus tack sharp any longer.
I’ve had it for ten years, and it’s taken several hundred-thousand shots. It’s been dropped onto carpet, linoleum, and concrete, from heights varying from 2 – 6 feet.
It’s been out in +35 C dry deserts, +35 humid Asian countries, and -30 Canadian prairies. It’s been canoeing, it’s been fishing, it’s been camping, it’s been hiking, it’s been walking in the rain, and shuffling in the snow. . .
I had it in for repair and a tuneup after the six-foot drop about five years ago. I don’t know if it would be worth it to try another tuneup.
I’ll give the Nikon factory repair centre in Toronto a call next week, but I suspect I may be better off in the long run by getting a new lens.
