PROBLEM TO BE SOLVED: To provide a blur correction device which is capable of reducing electric power consumption and deviations, a camera body and an interchangeable lens. SOLUTION: When a release SW turns on, a blur correction optical system starts driving. A timer starts measuring a lapse time t from the drive start time t=0. A shutter opens, and exposure is started according to the 'ON' action of the release SW. The blur correction optical system corrects the blur with high accuracy, at the exposure start and during the exposure. When the lapse time t attains the maximum time Tconst, at which the blur correction is possible, the blur correction optical system is held in the drive position, when this maximum time Tconst elapses. The blur correction optical system is held at the drive position until the exposure second time Tsh is attained, and thereafter, this system is locked. The electric power consumption, when the exposure time Tsh is long, is therefore reduced, and the accumulation of the errors of the blur correction is lessened, and satisfactory photographs can be obtained. |
