Two new 645N II Lenses
the 645 N, Pentax made history in the medium format sector. The first 4.5 x 6
single-lens reflex camera with autofocus has secured its outstanding position
among the pros as the ideal outdoor tool. With the 645N II, at the end of 2001
Pentax presented a version which has been optimized in line with the photographers'
At PMA in February 2002 Pentax is showing two new lenses
for these two models. These new lenses will enhance even further the already remarkable
flexibility of use of the convenient medium format cameras.
Pentax SMC-FA 645 Zoom 55-110 mm/F5.6
Light, compact, fast - the new standard
zoom lens offers a wide variety of features for the widest range of subjects.
The lens consists of nine elements in nine groups and has two exclusive Pentax
innovations. On the one hand it has an extra-low dispersion (ED) element, and
on the other hand it has the original Pentax "ghostless coating" for
sharp, brilliant and high-contrast pictures even of backlit subjects. The field
of view extends from 65 to 35 (corresponding to that of a 35 - 70 mm
zoom in 35 mm systems). The new zoom allows close-ups starting at 80 cm at up
to 0.16 life-size. The focusing can be changed over to manual.
wide-angle: Pentax SMC-FA 645 Zoom 35-55 mm/F4.5 AL
photography is unthinkable without the possibility of taking wide-angle pictures.
The new ultra wide-angle for the Pentax 645 range covers the traditional wide-angle
focal lengths (approx. 20 mm - 35 mm in 35 mm systems) in a single lens and thus
saves the photographer the trouble of changing lenses - to say nothing of the
weight saving in outdoor work. The lens consists of eleven elements in eight groups
with two aspherical elements for maximum image quality. While the hybrid element
minimizes distortions right out to the edges, the glass element prevents aberrations
over the entire zoom range. Naturally, the new wide-angle zoom has the exclusive
Pentax "ghostless coating" to prevent ghosting and to ensure sharp,
high-contrast pictures even of backlit subjects.
The close-up range starts
at 40 cm over the whole zoom range at up to 0.21 life size at the 55 mm zoom setting.
It is possible to change over to manual focusing.
