I am using a Tamron AF 18 - 250 mm lens on a nikon d90 and some times on auto focus F---- is displayed and i cannot take a photo. Is this something to do with the match of lens to camera ?

What worked for me: on the lens where it contacts the camera there is a little strip with metal leads. Unscrew that and there is a spring underneath. Stretch out the spring gently. Replace and then replace the leads strip and put the lens back on the camera. I haven't had a problem since.

Make sure the lens is set for the largest f number on the aperture ring. there may be a lock to prevent the ring from turning in the future. Locking the lens of the largest f number allow the camera to set the lens through the camera. This is normal on most of the newer cameras.
If the lens does not have a move-able aperture ring, then dismount and remount the lens, making sure the lens is completely mounted and locks into place, completely lining up the contacts inside. If this does not work The camera or lens may need servicing.
