One of the newbs in my schools photojournalism class murdered the focus mechanism on our two week old lens....... I was going to take it apart and snoop to try and see exactly what died but I don't know where to begin to take it apart...
send it to Nikon , believe me when I tell you that I have been taking things apart and putting them back together my whole life , folks call me all the time to "fix" darn near anything you can dream up and I can do it.
I Have taken a lens apart but i can tell you this I will Never try it again. Everything there is high precision , the screws are Very tight and if you bugger just one of them you make it even more impossible for a real tech to repair the unit
Save everyone the hassle and just send it to nikon , they will not repair the lens till they get an OK from you anyway
Ah yes but daniel has the more expensive AF-S version and he had an evil ref run him over...
We think that the girl who used my schools 80-200 last either A) got sand inside the lens freezing up the focus gear train or B) tried to turn the af ring while it was set in autofocus mode and stripped something... Shes not telling so and my school isnt going to make her pay for it.... (ugh.....)
if the camera is set to S or C and the lens is set to M and you turn the ring on the lens then it causes the motor in the camera to move , This set of circumstances can damage the camera
my thought is that this really doesn't hurt the lens but the camera motor
I have a jammed 80-200 lens too. Apparently my 2 year old son managed to get it and the barrel is now jammed. (How he got it in the first place and what he actually did still puzzles me). I think I might need a barrel replacement. Is it possible to get it replaced. The glass is still fine although the lens is still old and I have had some great pictures with it.
The push-pull collar does not lock up fully in manual mode and in AF mode, the lens is too tight to focus.

If that was so, why do they put the manual control on the lenses? I use that feature all the time on my 60mm Micro and a fair amount of time on my two ring 80-200 with the camera in S or C. Focus ring turns smooth too.

Gary , and others please take note as Not operating your equipment in the intended fashion Will after a time cause something to fail
Manual Focus on a Nikon body is properly done in the following fashion
Set Camera to M on the little switch on the body that has 3 markings C , S, M,
where C=Continuous focus as in tracking a moving subject
where S = single shot mode AF , AF is achieved by depressing shutter release half way
where M = Manual Focus
Set camera to M , Set Lens to M , this is the proper way to use Manual Focus on ALL Non AFS , Nikkor lenses , All AFD , and AFG Lenses need to be used in this manner.
IF you set the lens to M and do not set the camera body to M , then the focus ring on the lens causes the screw in the Body to spin and instead of being a Drive it is forced into being a Driven component.
