An imaging apparatus includes: a power supply; a first voltage converter producing first and second voltages which are different from each other based on an output of the power supply and outputting them to first and second output systems, respectively; a second voltage converter producing the first voltage based on the second voltage and outputting the first voltage to a third output system; an imaging element operated by the first voltage; at least one circuit element operated by at least one of the first and second voltages; a sensitivity setting section setting an input sensitivity of the imaging element based on at least one of a user's operation and information of a photographic subject; and a power supply switching section switching to supply the first voltage of the first output system to the imaging element in the case where the input sensitivity is lower than a predetermined sensitivity and switching to supply the first voltage which is outputted from the third output system to the imaging element in the case where the input sensitivity is higher than the predetermined sensitivity.
