A photographing apparatus includes a photographing optical system having a diaphragm and a photographing lens; an image sensor; a driver which drives a shake-correction member in a plane orthogonal to the optical axis to make the object-emanating light rays incident on pixels of the image sensor that have different in detection colors to obtain an optical low-pass filter effect, wherein the image sensor and/or a lens element-constitutes the shake-correction member; a retriever which retrieves information on an aperture diameter of the diaphragm and on a resolving power of the photographing lens; and a drive controller which varies a range of the pixels, having different detection colors and on which the object-emanating light rays are incident, in accordance with the information on the aperture diameter of the diaphragm and/or on the resolving power of the photographing lens to vary the optical low-pass filter effect.
