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