An imaging apparatus includes a half mirror that splits light from a subject having passed through a photographic optical system into transmitted light and reflected light, a first light receiving sensor that receives the transmitted light, the first light receiving sensor having a spectral sensitivity characteristic with a sensitivity peak at a specific wavelength of light, and a second light receiving sensor that receives the reflected light. The wavelength of a transmission peak in the spectral transmission characteristic of the half mirror matches the wavelength of the sensitivity peak of the first light receiving sensor.
