1. A method comprising:
a) providing a Tele folded camera that includes an optical path folding element (OPFE) and an image sensor;
b) tilting the OPFE in one or more directions to perform optical image stabilization (OIS);
c) while performing the OIS, capturing a stream of Tele images, wherein each captured Tele image is associated with a respective point of view (POV) and has a respective POV aberration in the shape of a non-rectangular tetragon that depends on a respective OPFE tilt position; and
d) digitally correcting the non-rectangular tetragon shape of the respective POV aberration into a rectangular shape based on the respective OPFE tilt position.
