This topic has come up many times, so I am posting two images. See if you can tell which was taken with a 99 cent UV filter from China, and which was taken with the naked lens. I'm not trying to make a point here. I just want to see if it makes a quality difference to the photos. My less-than-critical eye couldn't tell them apart.
Both shots were taken with a Nikon D5000 set on Auto, on a tripod - one right after the other.
Here are two more I just took with a D5100. Same 18-55mm. You can download these and see if there is any difference in the Exif data.
