Abstract
A camera acoustic indicating device for indicating, by sound, attainment of an in-focus condition of a camera objective lens and warning possibility of a blur occuring exposure time due to low brightness of an object to be photographed. The sound for the in-focus indication is intermittently generated at a frequency higher than that at which the sound for the blur warning is intermittently generated. When the attainment of an in-focus condition is detected while the blur warning is being made, the warning is interrupted for a given time period during which the attainment of the in-focus condition is indicated for a short time.
