ABSTRACT:
A camera shake compensating optical system has a first lens and a second lens from the object side. The image side surface of the first lens is convex to the object side. The object side surface of the second lens is convex to the object side. A direction in which a luminous flux is transmitted is slightly changed by a relative displacement of the second lens with respect to the first lens. By an obtained transmission deflection angle, blur of an image taken when the taking optical system is inclined is compensated for. The relative displacement is made so that an incident surface of the first lens and an exit surface of the second lens are not decentered from the optical axis of the taking optical system.
