The new lens is constructed using exceptionally high quality optical elements, and its range of focal lengths makes the lens ideal for both professional landscape photography and general everyday use.
Optical design consists of 15 elements in 10 groups, including four low-dispersed LD elements and two molded aspherical GM elements.
