Lock lens aperture ring at minimum aperture - Nikon D3000 10.2 Megapixels SLR Digital Camera with 18-55mm VR & 55-200mm DX VR Lens Kit

Yes. Just lock the lens aperture ring at its smallest setting (largest f/number). If you need to change the aperture, change it from the camera body by turning the command dial, the same way as with a lens without an aperture ring.

Turn the aperture ring on the lens to its smallest setting (largest f/number). You can control the aperture from the camera body, the same way as with a lens without an aperture ring.

The aperture ring is the one with a bunch of numbers on it such as 2.8, 4, 5.6, 8, 11, 16, and 22.

I'm surprised it works at all at f/2.8. The FEE indicates that the aperture ring is not at its minimum setting (largest f/number).

Turn the aperture ring to its minimum setting. You should be able to control the aperture from the camera body, the same way as on a lens without an aperture ring.

Then do so. Turn the aperture ring to its smallest setting (largest f/number). You can control the aperture from the camera body, the same was as with a lens without an aperture ring.

If it's on an SLR then it means the lens is not set to its minimum aperture. Turn the aperture ring on the lens to its smallest opening (largest f/number) and lock it if it has a lock. You control the lens aperture from the body, exactly the same way as on a lens without an aperture ring.

In order for the aperture to be controlled by the camera's program or primary and secondary control knobs, the lens must be set to the smallest opening - or highest number value f stop. The aperture must be operated by the ring if it is not left in the smallest opening position.

The FEE code you are seeing refers to a communication error between the lens and the camera body. Sometimes, simply removing the lens from the body and reseating it to the body will solve the problem. While the lens is off the body, carefully inspect the gold colored contacts on the lens and mating contacts on the camera body. Remove any dirt or debris found, being careful not to allow it to fall into the camera - or land on the back glass of the lens.

I found another explanation and possible remedy that stated:

"A flashing "FEE" is an improperly set aperture ring in 99.9% of all cases with this error message (i.e. user error). In very rare circumstances it can be caused by a damaged aperture ring (small lug broken from back edge) that can't "tell" the camera it is at the minimum position. If the aperture rings on the lens is set to minimum aperture (highest number) and locked there, but you still get a FEE error, it's possible that sloppy tolerances are causing the lens aperture ring to not move the little switch at the 8 o'clock position (on the D70 lens mount) as far as necessary to get a proper indication of minimum aperture. Try to see if the aperture ring (while locked) will move slightly when mounted on the camera to clear the FEE error.

Another remote possibility is that the little switch at the 8 o'clock position mentioned above is not functioning properly (sometimes they get dirty). Try "exercising" it by moving it back and forth with your finger, then try the lenses again. Usually FEE has nothing at all to do with CPU contacts (with a reverse engineered third party lens anything is possible I suppose), but it doesn't hurt to clean them to eliminate that possibility."

You can also try a different Nikon compatible lens. If the trouble is still present, the camera may need to be returned for repair. If the the problem goes away, then the issue is tied to the lens itself. This would mean the the lens needs repair.

I hope this helps and good luck! Please rate my reply - thanks!

You must lock the aperture ring to f/22, so the camera can engage the aperture adjustment lever on the lens. Then, you can change the aperture with the command wheel.

When you change the aperture with the command wheel the aperture ring on the lens doesn't move when the camera actually adjusts the lens aperture.

Take the lens off and locate the aperture adjustment lever on the lens mount.

Unfortunately, this won't work with older AF lenses. So if you are using an older lens, the only thing you can do is change the camera setting to M (Manual) to adjust the aperture on the lens yourself.

You're apparently using a lens with an aperture ring. Turn it to its smallest aperture (largest f/number). You control the aperture from the camera body, the same way as on a lens without an aperture ring.

If the lens doesn't have an aperture ring, clean the electrical contacts on the back of the lens and in the lens mount.

Since the 17-35mm AF-D lens has an aperture ring, it must be locked at its minimum aperture. You control the aperture from the camera, the same way you do so on a lens without an aperture ring.

Notes on G-type Nikkor and other CPU Nikkor lens
The G-type Nikkor lens has no aperture ring; aperture should be selected from camera body. Unlike other CPU Nikkor lenses, aperture does not need to be set to minimum (largest f-number). CPU Nikkor lenses other than G-type Nikkor lens have an aperture ring. Set the lens aperture to its minimum and lock. When the lens is not set to its minimum aperture setting and the power switch is turned on, "fEE" blinks in the control panel and viewfinder and the shutter cannot be released.
