PROBLEM TO BE SOLVED: To provide an automatic focusing device constituted so that a user can easily correct mechanical and optical errors. SOLUTION: This device is provided with a pair of CCD line sensors receiving an image formed by a telephoto optical system through a condensing lens and a splitting lens, an arithmetic calculation and control circuit 23 calculating defocus based on AF sensor data outputted from the CCD line sensor, and an offset dial 35 for correcting a defocus value and capable of being externally operated. In such a case, the circuit 23 adds or substracts an offset value(defocus value) set by the dial 35 to/from the defocus quantity obtained through the CCD line sensor 21c. |
