New lenses with breathtaking crispness
for over-dimensional formats

SCHNEIDER-KREUZNACH, the world-famous optical
corporation with an almost one hundred year history
and huge experience in the design and construction
of first-rate large-format cameras, has now entered
this field and has developed two lenses designed
especially for the large taking formats of fine
art photography. Both lenses are characterized by a
huge image circle of 900 mm which still leaves space
for camera movements to correct perspective and to
increase depth of field (according to the Scheimpflug
principle) even with the fine art size of 20 x 24 inches
(approx. 50 x 60 cm). However, the lenses are not
only unsurpassed in this respect: these exceptional
lenses also literally open up a new chapter in fine art
with regard to imaging quality. The crispness which
drops gently but distinctly toward the edge in the
older designs remains brilliant and perfectly uniform
over the whole image field at full aperture. Practically
no distortion is visible even in the wide angle
11/550 XXL Format at an angle of view of 78° in
critical architectural shots.
A high-quality broadband multi-coating effectively
reduces stray light, ghost images and other reflections
for enhanced contrast and incomparable detail
reproduction into the shadows. Filter threads at the
front and rear permit simultaneous use of two filters
(e. g. polarization filter at the front and a yellow filter
at the back) without the otherwise potential risk of
double imaging of bright points of light.
Both lenses come in the Copal 3 shutter, which
allows maximum aperture of f-stop 22 at 1100 mm
focal length, however. Normally, these lenses are
stopped down to at least 45 with these huge formats
due to the need for depth of field. For those who
need a larger aperture, the same lens is also available
without a shutter and with a maximum aperture of
14 as the Fine Art Lens 14/1100 XXL Format.
