Cylinder lenses are the essen-tial optical components of
an anamorphotic system.
A variation range of 2.5 f-stops between the fully open
aper-ture f/1.8 and f/4 allowes the setting of the aperture for
identical brightness of the image for all film and screen formats used
in the same movie theater.

The brightest anamorphic lenses
for
extremely large CinemascopeŽ screens
These lenses are composed of the
excellent
 Cinelux Premičre
base lenses and the proven
ES-Cinelux-Anamorphic 2x
attachment lenses and are designed for extremely large screens.
They represent the fastest CinemascopeŽ combinations and are
characterized by, among other things, extremely good imaging (detail
reproduction, modulation transfer) thanks to the use of aspheric lens
elements.
The sensational light output due to the
large aperture und high transmission and the ideally uniform light
distribution provide the brightest possible image with substantially
lower drop-off to the corners than previously possible even with the
largest screens and with the shortest base lens focal length of 42.5
mm.
The variable iris diaphragm of the
Cinelux-Premičre base lenses can be used, on the one hand, for the
individual adaptation of the illumination with different film sizes and
for the balance of the brightness loss due to lamp ageing and, on the
other hand, both for the increase of the depth of field for screens
with greater curvature and for a further improvement in the uniformity
of illumination.
The focusing and its locking take place
at its front with the supplied special tool and can also be carried out
with the lens in place. The special tool prevents accidental
displacement by unauthorized persons.
