ABSTRACT:
In a camera functioning with film speed data introduced by a manual operation for setting desired film speed data, exposure time data is set by a manual operation, and one of the film speed data and the exposure time data are alternatively indicated. The first and second indicating means are controlled, in response to first setting means such that the film speed data appears at the first indicating means when the first setting means is manually operated. The exposure time data is selected to appear at the first indicating means when the first setting means is not manually operated. The second indicating means is disabled when the first setting means is manually operated so that the film speed data appears without appearance of the additional data. The second indicating means is enabled so that the additional data appears with the exposure time data when the first setting means is not manually operated.
