I'm looking around for a decent composition for 11mm. I'll probably go back to downtown Atlanta where I can shoot some of the tall buildings up close. With their straight, vertical and horizontal lines it should give me a good idea of the lenses distortion. I'll post what I get. As to the exposure I was looking for the maximum depth of field. I was only about 15 feet from being directly under the sign. At f/20 at that distance the near limit DOF was 1.83 feet to infinity at the far limit. That guaranteed that everything in the shot from 1.83 feet in front of me to infinity would be in focus. Since nothing in the shot was moving, the sign dosen't blink or flash, an 8 sec. timed exposure tripod mounted was not a problem.</p></blockquote><p></p>
