Open to speculation here...

I have a 1st-generation Nikon 80-200F2.8 D lens.  Purchased new about
10 years ago for about $900 and used for years on various Nikons.

This lens used to work fine on my D70s as recently as New year's.
However, I took it out of my camera bag at a school function last
week, and it would no longer work on my D70s.   Camera just kept
flashing an 'FEE" error,  It will neither meter nor autofocus.  (And
yes, the aperture ring is closed all the way to F22 and locked).

At the same time, this lens still works fine on my fiancee's D80, and
my N90s and my 8008s cameras.  Just doesn't want to work on my D70s.

Some of my other lenses seem to work fine on the D70s, including:

18-70 dx
18-135 dx
75-300 F4.5-5

But the following quit working:
24 f1.8
50 f1.8
85 F1.8
28-85 F3.5

I'm guessing I broke something on the D70s.  A month ago I
accidentally put a Sigma 400mm lense on incorrectly, and really
struggled to get it off.  When I finally got it off (and I was pushing
it because I was starting a whale watch trip), I broke some little tab
- I thought from the 400mm lens.   Perhaps it was from the camera
instead though.

Now I've got a trip coming up to Hawaii in about 2 weeks, and I'd like
to see if I can get this situation fixed.
