To inexpensively perform photometry that is not influenced by reversely incident light without using an eyepiece shutter or an auxiliary photometric sensor.
A correction part 34 obtains an exact photometric value by arithmetically calculating a photometric value (photometric true value A') corresponding to incident light made incident only from an imaging lens 10 in an imaging optical system based on a first photometric value (photometric value A obtained for the first time) calculated when setting a first diaphragm value for the quantity of light incident from the imaging lens 10, and a second photometric value (photometric value B obtained again) calculated when setting a second diaphragm value for the quantity of light incident from the imaging lens 10 by a photometric sensor 18 calculating the photometric value from incident light made incident on a photodetector through the imaging optical system including the imaging lens 10.
