If a CPU lens is attached and a shutter speed other than is selected, the electronic analog ex-
posure displays in the control panel and viewfi nder show whether the photograph would be under- or
over-exposed at current settings. Depending on the option chosen for Custom Setting 10 (EV step;
89), the amount of under- or over-exposure is shown in increments of / EV or ⁄ EV. If the limits of
the exposure metering system are exceeded, the displays will fl ash.
