My Nikon d80 will not focus properly and seems to "hunt" for the focal point. While doing this the lens make a funny noise when trying to focus. r09 shows in the brackets in the viewfinder.

Check that the electrical contacts on the lens and camera body are clean, and that the lens is mounted fully and correctly to the camera, i.e. no damage or dirt in the mounts. If these are all okay, it is looking like an internal problem with the lens's focus motor, or possibly something jammed in the lens.

If possible, try the lens on another camera body. Alternatively, you could switch the camera to a manual focus mode (or a mode that doesn't require focus confirmation) and see if you can take a picture.

This pretty much rules out what you can do for yourself I'm afraid. If you still have no luck, you will probably need to take it to a camera store for inspection / repair.

(Incidentally, the R09 is not actually an error message. It means that you have 9 shot capacity in the camera buffer before it will fill up. It sounds as if the camera is set to an auto-focus mode that requires focus confirmation before the shutter will fire which is why you're seeing the message.)

Seems like your problem on greyish/blurry viewfinder is caused by the camera getting water logged. Get your cam cleaned by Nikon.

The flashing red light usually happens if you have this indicator set in the camera. This may not necessarily be an error.. just a setting that you have put in place in your menu.
