Abstract
When a photographing apparatus that is in a photographing enabled state but, at the same time, in a blur correction disabled state, is expected to be subjected to a shock, e.g., when an flash device in the photographing apparatus is about to be deployed, a blur correcting optical system is held at a constant position over a necessary length of time. In addition, at the start of a photographing operation, the blur correcting optical system is moved to a position at which the optical axis of the photographic optical system and the optical axis of the blur correcting optical system are substantially aligned with each other and the blur correcting optical system is held at the position. As a result, it becomes possible to dispense with a lock mechanism for holding the blur correcting lens and, at the same time, power consumption is reduced.
