Abstract: Lens assemblies according to the disclosure include an anamorphic lens component and a primary lens component. The anamorphic lens component includes a first cylindrical lens element, a second cylindrical lens element, and a first spherical lens element disposed between the first and second cylindrical lens elements and translatable along an optical axis of the anamorphic lens assembly with respect to the first and second cylindrical lens elements. Optical characteristics of the anamorphic lens component are adjustable as the first spherical lens element translates along the optical axis such that the first cylindrical lens element, the first spherical lens element, and the second cylindrical lens element in combination produce a first astigmatism that is opposite to a second astigmatism produced in an image plane by the primary lens component as an object moves from infinity focus toward the lens assembly.
