PURPOSE:To obtain a range finder which has a large degree of freedom in the arrangement of its optical system, and, at the same time, can be mounted on a small-sized camera. CONSTITUTION:This range finder measures a subject distance based on the synthesized sum of two outputs which are electrically processed so that ratio of the ratio of change of a first output against the reciprocal number of the subject distance from a first distance computing means 100 to the ratio of change of the output of a second distance computing means 101 can become a base length ratio L1:L2. |
