Imaging apparatus capable of determining whether an apodization filter is present or not and selecting first and second program diagrams

An imaging apparatus body in which a first lens barrel having an apodization filter and a second lens barrel having no apodization filter are mountable, the imaging apparatus body comprising:

• an imaging element that photoelectrically converts incident light so as to output an imaging signal;
• a stop that adjusts a light amount of the incident light;
• and
• an electric signal processing device configured for:
• performing photometry based on the imaging signal;
• storing a first program diagram in which an aperture value is fixed at an open aperture value in a case where an amount of exposure is equal to or less than a first amount of exposure, and a second program diagram in which an aperture value is fixed at an open aperture value in a case where the amount of exposure is equal to or less than a second amount of exposure which is greater than the first amount of exposure;
• acquiring subject information based on the imaging signal;
• determining whether the apodization filter is present or not;
• selecting the second program diagram in a case where the apodization filter is determined to be present by the determining and the subject information satisfies a first condition;
• selecting the first program diagram in a case where the apodization filter is determined to be not present by the determining, and in a case where the apodization filter is determined to be present by the determining and the subject information does not satisfy the first condition;
• and
• determining one group of an imaging aperture value and an imaging shutter speed based on an amount of imaging exposure which is calculated from a photometric value obtained by the performing photometry.
