<p>PURPOSE:To easily execute a photographing at a desired depth by setting the field depth by a field depth designating means, using an arithmetic circuit to obtain the depth and setting the diaphragm automatically or manually. CONSTITUTION:A diaphragm value setting switch 7 is depressed, an arithmetic circuit 13 is operated, a diaphragm value is displayed at a display 10, and at every time the switch 7 is pushed, the diaphragm value is changed over. It is selected by the operation of a mode changing-over switch 8 whether the diaphragm value priority mode is obtained or the shutter priority mode is obtained. Next, focus depth setting switches 9a and 9b are operated, and the position of the near point and the far point displayed at the display 10 is changed. Next, the light quantity from the object side is measured by a photometry sensor 12, the arithmetic circuit 13 composed of a microcomputer corresponding to this is operated, simultaneously, the focus distance of the lens is detected from the position of the ring for zooming by a lens focus distance detecting circuit 14, and the output is also sent to the circuit 13. Further, an AF sensor 15 and a distance calculating circuit 16 are provided, and the output is also sent to the circuit 13.</p> |
