An electronic imaging apparatus includes an optical system that has a reflecting surface for bending an optical path, and a variable-transmittance optical element placed in the optical system. The variable-transmittance optical element is constructed so that a ray of light passes through the optical element a plurality of times. Whereby, a slim-design electronic imaging apparatus can be provided which is small in size and extremely small in depth and in which the amount of light can be adjusted in a wide range.
