ABSTRACT:
A switch input unit detects the ON/OFF states of first and second release switches. A timer unit detects the input timings of the switches. A CPU controls a finder shift mechanism via a shift control unit in accordance with the timing detection results so as to switch the optical axis of a finder device. A multi-point distance measuring circuit for multi AF measures object distances at a plurality of points in a frame in accordance with an instruction from a point switching unit. The CPU re-controls the finder shift mechanism and the multi-point distance measuring circuit depending on the input states of the first and second release switches. More specifically, in a camera having a multi-point distance measuring device according to this invention, in order to take a picture free from a parallax by a simple operation, after an operation for switching the optical axis of the finder device is performed, distance measurement is performed again immediately before a photographing operation.
