If your Nikon D90’s shutter gets stuck when a lens is attached but works fine without it, the issue likely lies in the lens connection or the camera’s mechanical interface. Here’s how you can troubleshoot and fix it:
1. Clean the Lens Contacts
Dirty or oxidized lens contacts can cause communication issues between the camera and the lens. Use a microfiber cloth or a lens-safe cleaning solution to gently clean the gold contacts on both the lens and the camera body.
2. Check the Lens Mount Alignment
Ensure the lens is properly mounted and aligned. Remove and reattach the lens carefully, making sure it clicks into place. Misalignment can interfere with the shutter mechanism.
3. Inspect the Aperture Lever
The lens aperture lever might be stuck or bent. Remove the lens and gently check if the lever moves freely. If it’s stuck, try carefully adjusting it without applying too much force.
4. Test with a Different Lens
Attach a different lens to the camera. If the issue persists, the problem may be with the camera body. If the new lens works fine, your original lens may need professional servicing.
5. Reset Camera Settings
Sometimes, incorrect settings can cause shutter issues. Reset your camera to its factory settings by going to the menu and selecting the “Reset” option under setup.
6. Service Your Camera or Lens
If none of the above fixes work, the issue might be mechanical or electronic. Visit an authorized Nikon service center to have your camera and lens professionally inspected.
