In an embodiment, a folded camera module includes an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis, an image sensor and a lens module carrying a lens with a symmetry axis parallel to the second optical axis. The lens module can be actuated to move in first and second orthogonal directions in a plane perpendicular to the first optical axis, the movement in the first direction being for auto-focus and the movement in the second direction being for OIS. The OPFE can be actuated to tilt for OIS. ## Claims ### Claim 1 A camera, comprising: a lens module having a lens optical axis; an optical path folding element (OPFE) for folding light from a first optical path to a second optical path towards an image sensor, the second optical path being along the lens optical axis; and an OPFE actuation sub-assembly including one or more springs, wherein the camera is a folded camera, wherein the OPFE actuation sub-assembly is operational to tilt the OPFE for optical image stabilization (OIS) around a single OPFE tilt axis that is parallel to a first direction to compensate for tilt of the camera module, and wherein the first direction is substantially orthogonal to both the first and second optical paths. ### Claim 2 (depends on 1) The camera of claim 1, wherein the lens module is operational to be moved for auto-focus (AF) along a second direction substantially parallel to the lens optical axis. ### Claim 3 (depends on 1) The camera of claim 1, wherein the tilt of the OPFE is up to ±1 degrees from a zero position of the OPFE. ### Claim 4 (depends on 1) The camera of claim 1, wherein the OPFE actuation sub-assembly includes two springs. ### Claim 5 (depends on 4) The camera of claim 4, wherein a first spring of the two springs is positioned at a first side of the OPFE along the first direction and wherein a second spring of the two springs is positioned at a second, opposite side of the OPFE along the first direction. ### Claim 6 (depends on 1) The camera of claim 1, wherein the OPFE actuation sub-assembly includes a stationary base and a coil and a magnet, and wherein the coil and the magnet are positioned between a reflecting surface of the OPFE and the stationary base along the first optical path. ### Claim 7 (depends on 6) The camera of claim 6, wherein the magnet is rigidly coupled to the OPFE. ### Claim 8 (depends on 7) The camera of claim 7, and wherein the coil is rigidly coupled to the stationary base. ### Claim 9 (depends on 5) The camera of claim 5, wherein the OPFE actuation sub-assembly includes a stationary base, wherein one of the two springs is rigidly coupled to the stationary base at a respective first spring end and rigidly coupled to the OPFE at a respective second spring end opposite to the first spring end. ### Claim 10 (depends on 4) The camera of claim 4, wherein the two springs are leaf springs. ### Claim 11 (depends on 10) The camera of claim 10, wherein each of the two leaf springs includes two spring members. ### Claim 12 (depends on 1) The camera of claim 1, wherein the OPFE is a prism or a mirror. ### Claim 13 (depends on 2) The camera of claim 2, further comprising one or more position sensors that enable measurement of a position of the lens module and/or measurement of the OPFE tilt. ### Claim 14 (depends on 13) The camera of claim 13, further comprising an actuation controller configured to receive a data input indicative of the camera tilt and a data input from the one or more position sensors and to generate, in response to the data inputs, movement instructions and tilt instructions to, respectively, the lens and the OPFE actuation sub-assembly. ### Claim 15 (depends on 1) The camera of claim 1, wherein the camera module is included in a mobile device. ### Claim 16 (depends on 15) The camera of claim 15, wherein the camera module is included in a main rear-facing camera of the mobile device. ### Claim 17 (depends on 15) The camera of claim 15, wherein the mobile device is a smartphone. ### Claim 18 (depends on 15) The camera of claim 15, wherein the mobile device is a tablet.
