I have had the Nikon D80 w/ 18-135 lens for a few weeks and just lately notice a gray spot that occurs on every shot in exactly the same place, I checked that the lens is clean front and back, AF sensor is clean. Is this a defect or did I do something? I'm thinking about returning it to Circuit City right away but can I claim it was defective?.
Following your advice, I determined that the sensor appeared to be defective. The store person did accept it for exchange although it was in excess of their 14 day return policy. The new one I brought home is now doing exactly the same thing as the one I returned! I've used it very little and very carefully---no pointing it directly into the sun, etc. There is the same constant gray spot (in a different location on the screen). It appeared after shooting about 10 shots. (Using a new SD card, too)
Furthermore, this camera also has a dead pixel in the LCD screen. Is this a known issue with Nikon or what? I can't imagine what is going on here. Can anyone comment???Following your advice, I determined that the sensor appeared to be defective. The store person did accept it for exchange although it was in excess of their 14 day return policy.

Your sensor may have gotten dust on it to confirm this, set camera to a small aperture eg. f22 and take a picture of a white page then set camera to a large aperture eg f3.3 ant take the same picture. If it is dust you will see the spot on the shot taken at f22 and not the one taken at f3.3. This can be solved by having the sensor cleaned. If the gray spot is on both images you most likely have a damaged sensor

If the lens is only four months old then it's still under Nikon's warranty, so there is absolutely no point in trying to repair this yourself. Faults like these are most likely to occur in the first few months of use.
Just send it to the nearest authorised Nikon service centre or if you live in the UK you can demand a refund or exchange from the retailer. Given the choice, I'd strongly recommend the second option.
I think your lens are dirty. Buy lens cleaner from your nearest electronic store. Or do what I do, breath a mist on the lens and rub with a clean cloth. It always does a trick. Don't use glass cleaners.
There is a known defect in some of the Nikkor lens' that were manufactured during a certain time period. The same thing happened to my lens.. it stopped autofocusing for no reason at all. (It was purchased in May 08). I shipped it to Nikon and I received a new lens within 10 days of shipment. You have a 3 year warranty on the camera and the lens'. Nikon has AMAZING customer support when it comes to legitimate issues.
Go to the web site. Fill out a repair order and send the lens to them exactly as stated in the instructions. You will have a new lens within 2 weeks.
If you have another lens, switch it and take some shots of the sky. If the spot is gone, it probably was the lens that needs cleaning/servicing. However, it's more likely that there's dirt on your CCD. On your camera's menu, select mirror lockup/clean CCD (I can't remember the exact terminology but you get the idea).
After you select that, the mirror will stay up. Remove the lens and you'll see that the CCD is now exposed. Use a blower (don't use your mouth to blow as you will end up with spit in the camera) to clear out any dust/debris on the CCD. Don't touch the CCD.
Turn off the camera and you'll hear the mirror go back down. Re-attach your lens and try some shots.
