An image-taking apparatus includes an imaging device and a shooting lens of variable foal length, and generates image signals by forming a subject image entering through the shooting lens on the imaging device. The apparatus includes an angular-velocity sensor that predicts a shake that will occur at shooting by detecting a shake before shooting. The apparatus also includes a main CPU that controls exposure by adopting a shutter speed within a maximum shutter speed. The maximum shutter speed can be changed according to a result of shake detection and a focal length of the shooting lens to be used at shooting.
