Two FLD glass elements, which have the performance equal to fluorite glass have also been added along with three SLD glass elements, all which provide excellent correction of color aberration. In spite of the additions of all of these features, Sigma has managed to make the lens more compact than its predecessor, measuring only 7.8" in length.
