For a while ther I thought I was crazy. I just got a new Canon 1Ds Mark III in January. Because I shoot a lot of architecture, I have a grid focusing screen. As hard as I tried to create level images, time after time they were slanted down to the rght. Then I saw the post on LL with about 300 threads to it. In all of those threads, I have yet to read a solution.
My question is - does anyone know of a solution from Canon yet? Or are we supposed to simply deal with an $8,000 camera with a slight problem?
