An optical device capable of appropriately controlling a drive unit for moving a lens group included in an optical system is provided.

Conventionally, a small and lightweight zoom lens has been proposed which consists of first to fourth lens groups with negative, positive, negative, positive refractive powers arranged in that order from the object side to the image side, and in which the first and fourth lens groups are stationary during zooming and focusing (see Patent Document 1).
An object of the present
invention is to provide an optical device capable of appropriately controlling a drive unit for moving a lens group included in an optical system.
During zooming
, the lens control CPU 106 controls the motor 101 by feedback control using information from the rotation/position sensor 103. At this time, the lens control CPU 106 controls the motor 104 by open loop control in order to correct focus fluctuations that accompany the movement of the second lens group L2.
