I was out shooting with my D700 today, I was using either my 50mm f/1.4 or 85mm f/1.8 nikkor. Everything was going fine, but then suddenly the thing quit taking shots, and there was a fEE error in viewfinder, top display, and info screen. Turning camera off/on did nothing. I turned camera off, gave the lens a little wiggle back and forth, that did nothing. Finally, I took lens completely off and put it back on, and problem went away.
Any idea why this would happen? The lens WAS installed properly as I was taking many shots before the error appeared.
Any idea if it'll happen again? It was kind of bad timing.
It could be that the aperture ring was not locked down to the smallest aperture. With modern Nikon bodies, aperture is controlled by the camera body (typically the main or subcommand dial - depending on how the custom functions are set).
There should be a small tab near the aperture ring on the lens, shifting that tab should lock the aperture ring and prevent it from accidentally moving when on the camera.
I'm guessing that removing and remounting the lens rotated the aperture ring back into proper position.
I checked both my lenses and the aperture lock is firmly in place. I tried wiggling the aperture ring with the lock on a bit to see if I could reproduce the error, I was unable to. Hopefully it won't come back.
You guys are all correct, it was the aperture ring. It happened to me again today and I looked at the lens and the aperture lock was in the "unlocked" position and the ring turned. I have no idea how I have now, multiple times, accidentally moved that switch, but that's clearly what's happening. Must be how I'm putting the lenses in my bag or mounting/unmounting them or something
I have had this happen a number of times, but it is with a 200-400, which is a "G" lens. The contacts are very clean, weather fine, etc. When it happens, I turned the camera off, then back on, and it worked fine for a few thousand more pictures. Of course I checked if the card was seated, lens seated, etc. but everything was fine.
Not earth shattering, but always seems to happen at an inopportune time.
