Specifying Camera Settings in the EOS Viewer Utility Personal Function Settings Specifies the metering mode for manual exposure W O Select the metering mode to be specified. O You can specify the metering mode to be used in the manual exposure mode. O When you set the manual exposure mode, the metering mode selected here will be set automatically. In the manual exposure mode, this enables you to use a metering mode different from the one used in the AE modes. Sets the maximum and minimum shutter speeds to be used 4 O Select the maximum and minimum shutter speeds from the list box. O For example, if you set 1/2000 sec. as the fastest shutter speed and 1/60 sec. as the slowest, the shutter speed range will be 1/2000 to 1/60 sec. O This makes shutter speed selection faster and prevents a slow-speed sync. in aperture- priority AE mode with the flash. If you set the maximum and/or minimum shutter speed to one that is not a full-stop increment (such as 1/750 sec.), the controllable and settable shutter speed range might not be as exact as you set it (A slight deviation may occur.). This applies if you also set Custom Function C.Fn-6-1 and C.Fn-6-2 and set the maximum and/or minimum shutter speed to one that is not a full-stop increment (such as 1/3200 sec.). O To ensure that a proper flash sync speed is set in the Program AE mode, a shutter speed range of 1/200 sec. to 1/80 sec. cannot be set with the EOS-1Ds Mark II, EOS1D Mark II and EOS-1Ds, and the range of 1/400 sec. to 1/80 sec. cannot be set with the EOS-1D. O If safety shift has been enabled (with C.Fn-16), it will override P.Fn-04's shutter speed range. W-63
