This revolutionary lens is a recognized milestone in the development of lenses with adjustable focal lengths. With this lens it was possible to design an apochromatically corrected zoom lens with an optical performance that stands any comparison with lenses with fixed focal lengths - and that at high apertures! Even at full aperture, it is
impressive because of its outstanding definition across its entire focal length range. Coma and astigmatism are
practically non-existent. The two separate setting rings for focus and focal length make it especially easy to
select the right cropping of your subject. The lens is also equipped with a rotating and locking tripod mount.
