Hasselblad
250mm F/5.6 Super Achromat T* CFE Telephoto
Lens with leaf shutter 200 and 500 Series
Cameras
This lens features a
hitherto unachieved
level of chromatic
aberration
correction. It is
ideal for taking
photographs that are
to be enlarged
considerably and is
primarily used for
technical and
scientific IR
photography.
The secondary
spectrum, which is
the dominating
aberration of lenses
of long focal
length, has been
corrected for the
entire spectral
range between
approx. 400 and 1000
nm. Visual focusing
in visible light
guarantees optimum
sharpness even on IR
or false-color film.
This extraordinary
lens is ideally
suited for a wide
range of application
areas such as
special effects in
landscape and
architectural
photography,
geology, hydrology,
and archaeological
documentation with
the aid of aerial
photographs, botany,
plant pathology,
environmental
control, and
multi-spectral
photography. Since
the focusing ring
has no infinity-stop
position, focusing
for long-range work
must also be
performed using the
camera's focusing
screen. |
