Colleagues, I have been testing a tilt up/down attachment for my rotating pan camera and it is working great. It allows the camera to point up or down without giving a wavy horizon. I have to do more tests but with the 24mm lens it stays sharp at infinity with 15 degree tilts. There are examples and some other new pans on my web page: Chicago-Dance and Woods-Michigan.
