* f/2.8 - 60 mm
The 60 mm Makro-Planar
®
f/2.8 lens is a special
lens, the correction of which is optimized for close
range, whereas lenses for general photography are
optimized for long object distances. The design of
this lens corresponds to that of an almost
symmetrical Planar
range, whereas lenses for general photography are
optimized for long object distances. The design of
this lens corresponds to that of an almost
symmetrical Planar
®
lens, the correction of which is
remarkably steady with changes of the image scale.
If it is stopped down slightly more than normal
taking lenses with similar focal lengths, it can also
be used for long-range photography with
satisfactory results.

The helical focusing mount of the lens permits the
image scale to be continuously varied from 1:

to
1:1. The focusing scale goes down to engraving
0.27 m which corresponds to an image scale of
1:2. A second scale on the main mount permits the
reading of the image scale down to 1:1.

f/2.8 lens can be
recommended especially for the photographer who
has to change very often between overall shots and
detail photography. In animal and plant
photography as well as in industrial photography

large focusing range - ensures smooth
photographic work even in rapidly changing
situations.
