I read in Pekka's review of the 1DMk3 that you can limit shutter speeds with it.
Is there something similar with the 1DMk2N? I don't remember reading that in the manual, but for indoor bodybuilding shows, it would be my dream to use AV mode, and set an upper and lower limit for my shutter speeds (say 1/250s for lower and 1/400s for upper) since I know that the side of the stage is usually 1/250s and center is 1/400s.
