Changing the Focusing Screen You can change the camera's focusing screen to better suit the subject or shooting situation. You must also set C.Fn-00 so that the standard setting for obtaining a correct exposure matches the focusing screen.

Hold down the button and turn the dial to select [OK]. Then let go of the button. C.Fn-00 cannot be registered in any Custom Function group. If you do not change the focusing screen that came with the camera, you need not change C.Fn-00-1 factory setting. To change the focusing screen, refer to the instructions that came with the focusing screen. The Ec-A, Ec-B, Ec-I, and Ec-L focusing screens have a prism at the center. A correct exposure reading cannot be obtained with evaluative metering or spot metering based on the center area where there is a prism. Use center-weighted averaged metering or off-center spot metering with such focusing screens. 180
