Designed for use with OLYMPUS fiberoptic endoscopes. This condenser type
screen without fresnel lens requires no focusing when a special adapter
couples the camera with the fiberscope. Exposure is made automatically by
the light supply.
The grid lines engraved on the all-matte surface are used for vertical and horizon-
tal picture alignment. Though originally designed for architectural photography
with the shift lens, it is also suitable for general and super-telephotography, and
close-up/macrophotography with macro lenses and Auto Bellows.
Highly advantageous for close-up and macrophotography with Auto Bellows
and extension tubes. For focusing in low magnification close-up photography,
use the matte area and in macrophotography greater than life size, use the
double cross hairs the same way as with the 1-12.
The transparent screen offers the photographer focusing with an unusually
bright finder image. To focus, first correct your diopter using a dioptric
correction lens or Varimagni Finder so that each line of the double cross hairs
can be seen clearly and separately. Then bring the Spacemen into focus.
Most suitable for normal photography, this screen assures pinpoint focusing. The
central split-image rangefinder is encircled by a microprism collar. Since the outer
area has a matte surface, the screen can be used in the same way as the standard
1-1 and 1-3 Screens. When a lens with a maximum speed of F5.6 or slower is
used, the prisms darken and the focusing must be made on the matte area.
Most suitable for normal photography. The central split-image range finder,
encircled by a microprism collar, is inclined 45 degrees to allow easy focusing on
subjects with vertical or horizontal lines. When a lens with a maximum speed of
F5.6 or slower is used, the prisms darken and focusing must be made on the
matte area. The meter needle gives correct light readings.
