Nikon D5200: Reverse the Command Dial Orientation
When you use your Nikon D5200 to shoot in the P, S, A, or M exposure modes, you rotate the Command dial to adjust shutter speed and aperture settings. By default, rotating the dial to the right raises the value that's being adjusted: the shutter speed in S mode, for example, or the f-stop in A mode.
In M mode, rotating the dial to the right increases the shutter speed, and rotating the dial to the right while you hold down the Exposure Compensation button raises the f-stop value. In P mode, rotating the dial to the right raises the shutter speed and lowers the f-stop.
If that setup seems backward to you, you can tell the camera that you prefer to rotate the dial to the right to lower the values and rotate left to raise them. Just choose the Reverse Dial Rotation option, as shown on the left in the figure.
Look for the setting in the Controls section of the Custom Setting menu. Press OK to access the second screen in the figure, where you can modify the dial orientation separately for Exposure Compensation and shutter speed/aperture adjustment. To reverse the dial orientation, highlight the setting and press the Multi Selector right to place a check mark in the box.
In the figure, for example, the camera is set to reverse the dial orientation for both Exposure Compensation and Shutter Speed/Aperture. Note that the Exposure Compensation setting also affects the dial’s performance when you adjust Flash Compensation.
