PROBLEM TO BE SOLVED: To provide a range-finder capable of dealing with wide-ranging objects even through it is inexpensive and reduced in the photographing probability of a picture being out of focus by adopting the technique of so-called multi-AF that the optimum picture can be photographed without caring about a focusing point. SOLUTION: This range-finder is constituted so that at least one out of object light and reflected light from a 1st point out of the plural points in an image plane is made incident on a sensor array 4 through both of light receiving lenses 3a and 3b and the reflected light from the second point out of the plural points in the image plane is made incident on the array 4 through at least only one out of the lenses 3a and 3b. |
