I can't adjust this lens to the D80 - Nikon Normal AF Nikkor 50mm f/1.8D Autofocus Lens

The sensor on the D80 is smaller than a piece of 35mm film. This means the camera will only use the center portion of the image cast by the lens. This reduces the angle of view, effectively increasing the focal length. The 35-70mm will give you an angle of view similar to a 52-105mm lens on a film camera. Likewise the 70-210mm lens will give you an angle of view similar to a 105-315mm lens.

the lens is broken

Having gone over a month with no response, I assume this is no longer a problem.

What is the error message? If it is ERR then ERR message is not a good thing. Read page 132 of the D80 Manual. Also, try a factory reset found on page 129 of the manual. On the left side of the camera is the terminal cover, inside below the USB connector is the reset switch. If that does not work then it will need to go call Nikon digital 1-800-645-6689.

Not sure this will help you: In AF-S mode, the camera will not shoot until it acquires focus. Look on page 29 of the D80 manual. Now, does another lens make the same noise of only this lens. Can you try the lens on another camera? What this is attempting to do is eliminate the camera or, the lens, that way you know where to go next.

If your 70-300 lens is using VR and your 18-135 lens is not then this is correct. VR uses a lot of battery juice so you should try to keep it off if you are not using it. Also, try toset auto-focus off also if you are concerned about battery life.

The 50 mm lens is a full frame lens, and the D80 is a DX camera. This means that the 50mm lens puts an image out that is bigger than what the D80 can "see". The good part of this is that the D80 (and most of the other Nikon DSLR's) use only the image from the center part of an older lens. The bad part is that if you put the fisheye filter on it, the fisheye effect that is mostly seen at the edges of the lens doesn't show up on the D80 sensor. If you could put the fisheye filter on a DX lens, it would give you the full effect.

problem is in lens censer replace it

That depends. If the Quantaray lens has a Nikon mount, then yes, no problem, it'll work on the D80. If it has a different mount, then it won't fit onto the D80.
