Question about Nikon Zoom-Nikkor 18-200mm f/3.5-5.6G ED-IF AF-S VR DX Zoom Lens for DX Cameras
When my Nikkor 18-200VR focuses, I hear a rattling, rumbling and juddering noise. This is not the VR. (VR only makes a clicking noise.) I know it's not the silent wave motor because when I put the lens cap on, the focus spins from infinity to zero with a quiet swish like sound. When I take the cap off to focus (and swith off VR), it rattles and rumbles and to the focus lock on point. I've not used my D300 & 18-200 VR for a week or so but don't recall hearing this much noise from the unit. Has any body experienced this?
SOURCE: Camera won't autofocus
I too had D50 autofocus problems and ended up buying a new D300. I then learned that my issue was in the focus areas. The D50 has five focus areas. As you look through the lens, you will see one rectangle in the center and four to the top, bottom, left and right. You should make sure that the center rectangle is highlighted. Use the round thumbdial on the back of the camera to move the focus area.

If you just purchased the lens I would take it back sounds like the lens is jarred and defective should still be on warranty

hi ! iam too a D40 holder,u can opt for AF-s versions or HSM sigma,both of them autofocus on d40,can go for 18-200 AFs VR or if u need still longer end go for 70-300 but it is costly than the sigms 70-300APO DG HSM MACRO..,its a much better reviewed lens and dont forget the cost..anyway do some research before considering..good luck

Your lens has an aperture issue,sounds like you may have an element of glass not locking into place correctly.
Send to manufacturer for repair.
Or back to the shop if under warranty.
If the lens has been dropped...its probably on its way out now.
Does the camera work with other lenses ?

Please check your focus settings in the camera menu. Play around with the focus point from Single to 11 points. Also, try Auto mode as a quick way to test if the focus is working
