    I received a couple messages saying that there's horrible jpg artifacts and oversharpening problems. Unless the Gigapan stitch program changes the files to JPG those statements can't be right since the files went from RAW with very minor sharpening ( 3) to TIFF and directly to the Gigapan stitcher. I think what they were looking at was the combination of atmospheric distortion from the heat coming off the buildings and the compression of the atmosphere caused by the long focal length of the lens. It's similar to seeing what appears to be water on the road when it's really hot outside and when you get to the spot you find that it's not there. So, when you pixel peep in the distance and see distorted windows, buildings and cranes, it's not because of some computer compression scheme or a lousy lens, it's because of the forces of nature and optics.
