Customer Question

I have a Nikon D80 camera with an 18 to 135mm lens. When I try to take a photograph and press the shutter, the lens keeps moving in and out and more often than not no photograph is taken. It would appear that I have perhaps accidentally changed a setting. Can you help me?

First, if you wish to focus manually (using the focus ring on the lens) the switch should be in the M position. If you are trying to shoot with manual aperture and shutter speed settings, but still want to use auto focus then the switch should be where you have it, AF-A.

If you are trying to use auto focus and it is hunting and unable to find a focus point please do the following:

Reset the camera using the instructions below

Then detach and reattach the lens, clean the contacts on both lenses and camera body where the lens is mounted with an eraser. Be careful to not allow residue to drop into the camera body. Bad communication between the lens and the camera can also cause of this error.

Finally, the one most likely thing that even experienced photographers miss is that a single small spot or smudge on the lens can cause the problem that you are having. Carefully clean the lens and look for any scratches.

If the camera does not complete focus, the shutter will not fire. Please let me know the result.

Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well.
