PURPOSE:To display a two-zone focus type adjusting result by using an infrared ray emitting diode to display a focus detection adjusting result. CONSTITUTION:The two-zone focus type focus detector having two focus zones and using the distance measuring infrared ray emitting diode 1 has a means using the diode 1 to display a focus detection adjusting result. When the output of a changeover switch 10 is turned to a low level by depressing an adjusting mode changing switch 10, an adjusting mode is set up and waited until a high level is returned to adjust the focus detector during the period. When the focus detector is correctly adjusted, the diode 1 is continuously turned on and off. If the focus detector is not correctly adjusted, the light emission of the diode 1 is stopped. Consequently, a focus detection adjusting result can be displayed. |
