Why won’t my Nikon D7000 control the aperture on a 50mm f/1.8D lens?

I’m using a Nikon D7000 with a Nikkor 50mm f/1.8D. The lens aperture ring is locked at f/22 as recommended, but the camera still won’t change aperture in Manual, Aperture Priority, or Shutter Priority. The only way I can change aperture is by unlocking the lens ring and turning it manually. Is the lens defective, or is there a camera setting I need to change?

The D7000 has a custom setting that allows you to use either the camera or the aperture ring on a 'D' lens to select the aperture. For the camera to control the aperture, be sure you have selected Sub-command dial (and not Aperture ring) in the Custom Settings menu-->f6: Customize Command Dials-->Aperture setting. It is on page 233 of your D7000 User's Manual. If Aperture ring is selected then the D7000 will behave as you have described in your question.

The lens is probably not defective. On the Nikon D7000, there is a menu option that determines whether aperture is controlled by the camera’s command dial or by the aperture ring on older Nikon D-type lenses.

Check: Custom Settings menu → f6: Customize command dials → Aperture setting

Set it to Sub-command dial, not Aperture ring.

If Aperture ring is selected, the camera will behave exactly as you described and require you to turn the lens ring manually. For normal camera-body aperture control with the 50mm f/1.8D, keep the lens locked at f/22 and use the Sub-command dial setting.
