description An optical image stabilization device (1), said device comprising a first frame (2) configured to accommodate an imaging module (3) and a first actuation unit (4) comprising at least one actuator (5). Said actuator (5) comprises a bending arm (5a) and at least one shape memory alloy member (5b) configured to bend said bending arm (5a) such that a free end of said actuator (5) may fasten said first frame (2), thereby generating a pivoting movement of said first frame (2) around a first pivot axis (A1). Said device (1) may comprise a second frame (6), the second frame (6), the first frame (2), and the imaging module (3) being arranged in a nesting arrangement. By differentiating the pivot points for the second frame and the first frame, multi- axial rotational movement is facilitated.
