Switching formats on the SINAR f2 and
f1
Release the bellows at the lens end and remove together with the whole rear
standard (the coupling frame is here fixed
to
its standard bearer). Now fit the
required alternative rear standard
(5
x
7"/13
x18 cm
or
8x1 O"/18x24 cm) with
its matching tapered bellows
in
the usual way. Format changing
is
thus sim-
ple and rapid. The basic design
of
the rear standard
is
the same for all three
formats but the
two
larger sizes are reinforced and the optical axis is recen-
teredo Operation
is
the same as with the 4x5"/9x12 cm rear standard. The
rear standard left over after switching formats remains part
of
the SINAR
system
to
serve as an auxiliary
or
intermediate standard.
The SINAR f2 special front standard
For the
5x7"/13x18 cm and the 8x1 O"
/18
x24 cm versions
of
the camera we
recommend the 431.62 SINAR f2 special front standard. It provides a larger
shift range as its zero positions are specially
al
igned for these larger formats.
The heavy-duty construction is also more rigid. This special lens standard
is
part
of
the 5x7"/13x
18
cm and the 8x1 O"
/18x24
cm SINAR f2 outfit.
The convertible camera
The SINAR f2
is
the entry point
to
the versatile SINAR system with its fully
compatible components. As requirements become more ambitious, chang-
ing the rear standard converts the f2
to
the SINAR c2. If you then replace the
lens standard
by
that
of
the p2, you have a complete SINAR p2. All elements
other than the alternative camera standards remain the same. Components
left over have further applications in the SINAR system. With just a few addi-
tional parts you can even use them
to
assemble a second camera.
