| 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. |
