Abstract: An imaging apparatus includes a front lens group having a front lens element and a prism, in that order from an object side, light rays exiting from the front lens element along a first optical axis being reflected by the prism to travel along a second optical axis nonparallel to the first optical axis, a rear lens group, and an anti-shake system. The anti-shake system includes a base member supporting the prism, a movable frame supporting the front lens element; and opposing guide members on opposite sides of the prism on both sides of a reference plane, respectively, in which the first and second optical axes lie, to support the movable frame to allow the movable frame to move along the plane orthogonal to the first optical axis relative to the base member.

Abstract: An imaging apparatus includes a front lens group including a front lens element and a prism, a prism holder which supports the prism, a movable frame which supports the front lens element and is supported by the prism holder to be movable along a plane orthogonal to the optical axis, and a driver which drives the movable frame to reduce image shake. The driver includes a permanent magnet and a coil positioned in a magnetic field of the permanent magnet, wherein one of the permanent magnet and the coil is a movable element which is fixed to the movable frame to move with the movable frame, the other of the permanent magnet and the coil is a fixed element, which does not move with the movable frame, and a position of the fixed element is determined by the prism holder.
