Top-notch Lenses
Neutral colors
Due to different glass types used for the different lens
elements, lenses may exhibit subtle differences in color
rendition. The design of dedicated Rollei lenses there-
fore places special emphasis on reducing these color
variations to an absolute minimum. In practical terms
this means that pictures taken of one and the same
subject with different lenses will have identical color
characteristics and can thus be combined without any
problem.
Sharpness
This is the product of the resolving power and contrast
rendition of a lens – criteria that are given great impor-
tance in the design of Rollei camera lenses. Precise
focusing is easy due to the bright focusing screens of
Rolleiflex 6000 Series cameras (and the fast and precise
autofocus of the Rolleiflex 6008 AF) and makes sure
that your pictures are tack-sharp.
Lens speed
Lens speed, or the aperture ratio, is an important crite-
rion for choosing lenses. The higher the speed of
your lenses, the longer will you be able to shoot
without a tripod or flash unit and the easier the use
of selective focus for creative composition. High lens
speed and high performance, however, are difficult
to reconcile. Still, the high standards employed in
the design and production of Rollei lenses are your
guarantee that even at full aperture your pictures
will be brilliant and sharp from edge to edge.
Flare reduction
In addition to anti-reflection coating, additional care is
taken to minimize flare. Special black varnish blocks out
light that might be reflected into the optical path, and a
separate pin-hole diaphragm cuts off any and all light
rays that are not required for image formation. (This
pin-hole diaphragm should not be confused with the
iris diaphragm that is needed for exposure and depth-
of-field control.)
Precise aperture control
The aperture, on the one hand, controls the amount
of light reaching the film, on the other the depth of
field in your pictures. At wide apertures, depth of field
is shallow. Only the plane you have focused on will
appear sharp, the fore and background being blurred.
Owing to the almost circular shape of the lens aperture
in Rollei lenses, the transition from sharp to blurred
is very smooth and pleasing, while reflections in
the blurred portions of the subject appear round and
natural.
Specially designed for Rolleiflex 6008 AF cameras, there
is a line of pioneering autofocus lenses. These latest
lenses by Schneider-Kreuznach provide a degree of
focusing comfort that makes full use of the high speed
of the 6008 AF. Thanks to fast and precise focusing,
you can concentrate fully on your subject.
On a Rolleiflex 6008 integral, 6003 professional or
6001 professional, these AF lenses may be used with
manual focusing.
