Question about Tamron AF 28-80mm Lens
Lens is making a clicking sound when trying to focus, what do I need to do?
This is usually a torn flexible circuit or binding aperture in the lens. It'll have to go to a repair shop for replacement. About a $80 job.

You probably have to set the aperture manually on the lens, because it
might not have CPU contacts. I think changing the aperture on the
camera will probably have no effect, so just try twisting the aperture
ring to wide open.
You usually have to set the aperture at the minimum setting (highest number) so that if the camera is choosing the aperture, it can stop down to the required value.
No good having it set at f2.8 if the shot needs f11.
If the lens is very old, it might have a manual iris that you have to set yourself on the lens. The lenses that stop down automatically will have a tiny peg on the mount that a suitable camera can operate. Gentle pushing of this peg while looking through the lens will tell if it is stopping down - set it wide open first.
If you have a depth of field preview button, this will also have the same effect with the lens on the camera if the body matches up with the lens.

There should be a switch just in front of the back of the lens marked "AF" and "M". Set it to M for manual focus, AF for autofocus.

It is dealing with the films. when closing the lens in the fabric, the electrical film changed its position to an unwanted situation. This makes noise sometimes. It is not important for functinality of the lens. But it only gives you an unwanted noise. There is nothing to do because film dries as the times passes. It needs to be changed but is not cheap. So it is better to go on to use it.

Hello. Yes it can be repaired. Take it into your local Nikon shop for a free estimate, it is often the case that all these lenses need is an internal cleaning and lube and then they are good to go again.
4 thumbs up please. ty
