The anamorphic objective lens systems (100LS) and processes for the formation of a set of anamorphic objective lens units (100 (i)) with different focal lengths (FLY), which comprise a front anamorphic building block (20) and a set of two or more non-anamorphic building blocks (50 (i)) use. The non-anamorphic building blocks are optically matched to the front anamorphic building block, and their front ends (52) are designed to be easily attached and detached from the rear end (24) of the front anamorphic building block in order to allow the anamorphic object lens units with the different To generate focal lengths. Since the anamorphic objective lens system uses only a single front anamorphic module and multiple non-anamorphic attachments, the cost of using the multiple anamorphic objective lens units is reduced compared to using individual anamorphic objective lenses for each of the desired focal lengths.
