PURPOSE:To provide a camera equipped with a range-finding device which does not require troublesome manual operation, which controls focusing in a range-finding unfeasible area being a long distance based on the diaphragm value of a photographing lens, and in which AF by the luminance of a subject is deteriorated. CONSTITUTION:This camera is equipped with an arithmetic control circuit (CPU) 10 controlling various kinds of arithmetic operation and an entire device, an infrared light emitting diode (IRED) 1 projecting light for range-finding to the subject, an optical position detecting element (PFD) 4 receiving reflected light from the subject and photoelectrically converting it, and the range-finding device extending the photographing lens 12 based on at least one detection signal and the luminance of the subject which are obtained, selecting an optimum step pattern from plural step patterns previously set in order to control focusing and controlling focusing according to the selected pattern. |
