Hi Mestre, welcome to the Nikonites Community. Also add your camera to your profile. As Jack says all of this information will help us answer your question. The D80 is a very good camera, I shot with one for a couple of years. The camera performed a lot better than I did. We would love to see some of shots of Lisbon in your gallery. A beautiful place to take pictures. This is a good site with a lot of experienced Nikon users to answer your questions and a very friendly place just to talk photography. Enjoy.
