    This paper describes a type of lensing that is between the strong and weak-lensing limits: only single images are formed, but lensing introduces a measurable curvature to the galaxy shape. There is some theoretical promise for this "flexion" improving the combination of strong and weak-lensing data, but current attempts to measure the effect have shown it to be difficult.
