Various embodiments include a camera having a sensor-shifting mechanism. For example, the camera may include a voice coil motor (VCM) actuator to move an image sensor, relative to a lens group, to provide autofocus (AF) functionality. According to some embodiments, the VCM actuator may include one or more coils attached to a coil carrier, and one or more magnets attached to a stationary structure of the camera. The coil carrier may be attached to an image sensor package such that the image sensor is movable together with the coil carrier, in at least one direction parallel to an optical axis defined by the lens group. In some embodiments, the camera may include one or more suspension arrangements to suspend the coil carrier and/or the image sensor package from one or more stationary structures of the camera.
