A camera includes a camera actuator having autofocus (AF) voice coil motor (VCM) with a lens carrier mounting attachment moveably mounted to a base, magnets mounted to the base, and an AF coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of a lens of the lens carrier. The magnets may include a pair of first magnets laterally spaced along a first side of the camera and a pair of second magnets laterally spaced along a second side of the camera opposite the first side. The optical image stabilization (OIS) VCM includes an image sensor carrier moveably mounted to the base, and OIS coils moveably mounted to the image sensor carrier within the magnetic fields of the magnets, for producing forces for moving the image sensor carrier in directions orthogonal to the optical axis.
