I have an 18-200mm AF lens the early VR type and I have begun to suspect that the AF mode is not working as well as it should. I have have found that in low light it is slow or unable to focus. This may be characteristic and ok. Simply put: is there a way to rest this lens? I have surfed the net without success. Short of sending it in to a lens repair shop [ big bucks one quoted $200 you can pick then up for $ 300 $ 350] what do you suggest? In bright light, I have found that the AF is slow. When I compare it with my 70-300 the AF is much slower. Thanks for taking the time to read.

Thanks for your interest. Using D300. Not much into action shots, but find that moving camera from close to long shots can be frustrating in certain conditions due to slow Af. I must say that maybe the AF is okay but when compared to my 80-300 it is slow. Ken Rockwell ,in his appraisal of the 18-200 remarked on its focus speed as being very good.

Thanks. Ideally, someone nearby me would offer to let me make a comparison with their working 18-200. In that situation, an answer could be had in a few moments.

I have one you could borrow--but I live in Miami and now is a bad time to visit Miami.

Sandbags might work but it might prefer to rest on one of your cast off pillows.

Thanks for the offer, but I'll try to find someone a bit closer.
You just don't want to go to Miami and I don't blame you!

I have a D300 and the same 18-200 lens. I think the lens was the kit lens. I haven't usrd the combination for a while, so I just took them outside. While slow is a relative thing, compared to newer lenses, the focus is slow.
I just mounted the lens on a D500. While not a speed demon, it was a lot faster.
Both cameras had fully charged batteries and vertical grips with fully charged batteries.

I appreciate your effort in helping me. The 18-200 is a wide angle zoom AF and was offered separately. The current iteration VRll is selling for $600 plus. You may have put my mind to rest on this issue with your results. Thanks.

I suspect you may have a little dust on the AF sensors or the contacts may need a little cleaning. Hope it helps.

Get your 25 gallons of water, fill your bathtub with water for the toilet, stock up on food, cover the windows, hunker down and pray the projected path will change. Oh, make sure the inflatable raft has no leaks. Good luck to you. Keep the camera's on a high shelve.

And charge up camera batteries.
