A distance measuring system for a camera includes a plurality of light sources arranged in a row, and a receiver for receiving light reflected from a subject. The receiver outputs a signal corresponding to the position thereon at which light is received, and is a function of the direction of propogation of the light from its source and the distance to the object. The distance to the subject is calculated from the output of the receiver. The sources are selectively energized by manual control so that the system is adaptable for measurement in a plurality of different distance ranges. A display may be provided to mark a spot on an image of the subject, to enable the user to determine the subject that had been used for the distance determination.
