An exposure meter includes a plurality of indicating elements, such as illuminating diodes which are turned on by the output of a photometry device and the diodes are repeatedly turned on and off by the output signal from a switch. This turn on and turn off of the diodes can be reversely effected. By so doing, a preset shutter speed or stop value is indicated in the finder and pointer-follow function of the exposure can be achieved using the minimum number of diodes.
