When using a Nikkor 70-200 MKII my D5100 will occasionally give me the f ee error. This doesn't make sense b/c the 70-200 doesn't have an aperture ring. I have used other lenses (14-24 and 17-35) on the 5100 and the 70-200 on other bodies (300s and 7000) and everything works fine. Nikon's customer service didn't want to listen when I said I was using a lens without an aperture ring. So my question is "has anyone else had lens-body communication issues with their D5100?"

You're on the right track, as the "F-ee" error usually shows up when the aperture ring isn't locked at the smallest aperture. And again, you're correct, as the excellent Nikon 70-200mm f/2.8 doesn't have an aperture ring. I did a little research and found that your problem might be dirty contacts on the lens or camera body. http://support.nikonusa.com/app/answers/detail/a_id/2605/~/what-does-the-fee-or-f---error-message-displayed-on-an-slr-camera-mean%3F
Generally it is an issue of not making good contact.
Get some isopropyl alcohol and lightly dampen a q-tip, and clean the sensor pins on the camera mount and see if this helps.
When you purchase the alcohol, go to a drug store and look for 99% alcohol if you can find it. Much of the cheap stuff you find in grocery or department stores is around 60% alcohol, which means it has 40% water in it. You want as high a concentration of alcohol as you can find as you don't want water residue left on the contacts after cleaning them.
Or find a good contact cleaner at an electronics store.
