I have a new D7100. In Shutter Priority should I be able to adjust the aperture with the sub-command wheel? I thought in SP the camera chooses the A. On my D90 when I am in SP nothing happens when I turn the Sub-command wheel.
SO I am clear, I have the camera set to "S" I can adjust the shutter speed with the command wheel. I realize that is normal. But I can also adjust the the sud-command wheel which changes the aperture. So it works like manual "M". Should this be happening or is there a problem with the camera?
