An optical element including a plate-shaped substrate with a light-entrance surface and a light-exit surface, a multiplicity of imaging elements formed on the light-exit surface and a multiplicity of diaphragms formed on the light-entrance surface. Each diaphragm includes a transparent geometric region in an opaque region. The optical element can be switched between two operating modes B1 and B2 such that some of the imaging elements change their focal length between values f1 and f2 and/or, some of the diaphragms change their aperture width and/or their position. Exactly one diaphragm is associated with each imaging element in mode B1 so that light passing through the diaphragm is imaged or collimated by the associated imaging element. Consequently, light arriving in the optical element through the diaphragms and then through the light-entrance surface has, after passing through the associated imaging elements in the two operating modes B1 and B2, different propagation angles.

A camera may include at least one suspension assembly as part of optical image stabilization and/or autofocus systems of the camera. The suspension assembly may include an inner frame, an outer frame, and one or more flexure arms. Electrical traces may be deposited at both sides of the suspension assembly. A connection may be created, for electrical traces at the different sides of the suspension assembly, through the suspension assembly by removing (e.g., using an etching process) one or more parts in the body of the suspension assembly to create one or more cavities. A remaining part of the suspension assembly surrounded (and thus isolated) by the cavities may thus form at least a part of the connection for the electrical traces. The connection may further include one or more filled trenches connecting the electrical traces to the remaining part of the suspension assembly.
