If your Nikon LCD displays "Err" message, or pictures turn out to be terribly dark.
Your camera could have a defective aperture control unit.
Sometimes you'll be able to get a photo or two and then the ERR comes back.
This service includes DEEP CLEANING your camera body, getting all that dust and dirt out that has accumulated, REPLACE the aperture control assembly and reset electronics.
Your camera will come back working just like it should!
