The reason I started this thread is that I was making an image basically of an old barn's window and an arrangement of reflections in it. The casing nearly filled the frame with the 90mm lens. I was only a couple feet away from and pointed almost directly at the barn wall, but offset enough to get the camera out of the window's reflection. There was not enough swing in my field camera to straighten out the convergence of the window's casing and I wasn't that far out of perpendicular to it so I was very frustrated. It's those kinds of shots that I would like movement enough to get because the window casing is whacked when it looks like a trapezoid.
