  The lens body 7 includes a focus lens unit, a zoom lens unit, and an iris unit (not shown), which are driven based on commands from the lens control unit 8.

  The focus processing unit (focus detection means) 9 of the lens body 7 calculates the focus position for the subject in the focus detection area in the shooting screen (detection of focus state), and the lens control unit 8 calculates the calculated focus position. Based on the above, a signal for driving the focus lens unit is output.

  In addition, the lens control unit 8 transmits a signal related to the movement of the focus detection area to the camera body 10 so that the focus detection area moves in the movement direction associated with the operation direction of the operation unit 1. Then, the camera body 10 transmits a signal related to the movement of the focus detection area received from the lens body 7 to the focus detection area display unit 11 to move the display position of the focus detection area in the finder. In the present embodiment, the focus processing unit 9 is disposed on the lens body 7. However, when the focus processing unit 9 is disposed on the camera body, the focus detection area received from the lens body 7 is moved. The focus detection area for calculating the focus position is changed on the basis of the signal regarding.

  FIG. 2 shows the focus demand 12. FIG. 3 is an explanatory diagram of a usage state of the imaging apparatus including the focus demand 12.

  The focus demand 12 includes an operation knob 12a for operating the focus and a focus demand main body 12b, and is connected to the lens main body 7 via the cable 14. When the focus demand operation knob 12a is rotated, a focus command signal for driving the focus lens portion of the lens body 7 is output. The focus demand main body 12b is fixed to a clamper portion 17 attached to an operation rod 16 for operating the imaging device fixed to the tripod 15.

  A focus detection area operation unit (operation device) 5 is integrally formed with the focus demand main body 12b. The focus detection area operation unit 5 includes an operation unit 1, a setting unit 2, a focus switch 3, a moving direction display unit 4, and a setting mode switch 6, and each is controlled by a lens control unit 8. The autofocus control is switched on and off by the focus switch 3. When the operation unit 1 is operated, a command signal for the movement direction of the focus detection area is output. The setting unit 2 is provided with up / down / left / right switches and movement prohibition switches corresponding to the moving direction of the focus detection area. The movement direction display unit 4 displays the movement direction of the focus detection area corresponding to the operation direction of the operation unit 1, and displays up / down / left / right or movement prohibition of the set direction. The setting mode switch 6 is a switch for switching ON and OFF of a setting mode for setting the operation direction of the operation unit 1 with respect to the moving direction of the focus detection area.

  FIG. 4 shows a flowchart for setting the operation direction of the operation unit 1 with respect to the movement direction of the focus detection area. When the moving direction setting mode is entered by operating the setting mode switch 6, the up / down / left / right switch and the movement prohibition switch of the setting unit 2 can be selected. The setting unit 2 has five switches, and each button is prohibited from moving in the four directions of right 2a, left 2b in the horizontal direction, up 2c in the vertical direction, and down 2d in the focus detection area. "2e is allocated. After pressing one of these switches (after selecting one switch), if the operation unit 1 is operated in a certain direction, the direction in which the switch of the setting unit 2 is pressed and the operation unit 1 are operated. The direction is set to correspond. Further, when the operation unit 1 is operated in a certain direction after “−” 2e is pressed, the direction in which the operation unit is operated is set as a direction in which the movement of the focus detection area is prohibited. By repeating the above setting, any operation direction of the operation unit 1 can be made to correspond to the moving direction of the focus detection area. When ending the movement direction setting mode, the setting mode switch 6 is turned OFF to end the movement direction setting mode.

  FIG. 5 is an explanatory diagram when the focus demand 12 is rotated 45 ° clockwise from the position of FIG. 2 and fixed to the clamper unit 17. When the focus demand 12 is fixed in this way, the operation direction of the operation unit 1 corresponding to the vertical direction of the screen may be set to a different direction depending on the photographer.
