Claim 25:
26. A mobile phone comprising:
a shape memory alloy (SMA) actuator assembly to tilt a movable object comprising a mirror or prism relative to a static part, the actuator assembly comprising a plurality of SMA wires, wherein:
the actuator assembly is arranged to tilt the movable object about an axis;
at least one SMA wire is hooked to a feature of one of the movable object and the static part at a location between the ends of the SMA wire;
the feature extends in a direction orthogonal to the axis, forming two sections of the at least one SMA wire on opposing sides of the feature; and

the two sections of the at least one SMA wire are angled relative to each other when viewed in a direction orthogonal to the axis and orthogonal to the direction the feature extends; and
a control circuit configured to drive the actuator assembly to effect optical image stabilisation.
