Switching formats on the SINAR
f2
and
fl
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
(5x7'713x18
cm or 8x10'7'18x24 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-
tered.
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"
/13x1 8 cm
and the 8x1 0'7'l 8x24 cm versions
of the camera we
recommend
the 431 .62
SINAR f2 special front
standard. lt
provides
a
larger
shift range
as its zero
positions
are specially
aligned forthese largerformats.
The heavy-duty
construction
is also more rigid.
This special lens
standard is
part
of the 5x7"
/1 3x1 8 cm and the
8x1 0,71 8
x24
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.
lf
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.
