When fitting lenses line up the red
dot
at the rear of the lens board with the
red
dot
on
the behind-lens shutter. Insert the lens board and lock. The aper-
ture controls then couple automatically.
The bellows
Folding bellows
The folding bellows should never sag - so
do
not place anything on
top
of
them. Also,
to
counteract sagging, periodically refit the bellows inverted
about their axis.
The wide-angle bellows
To
permit infinity focusing with short camera extensions pull any folds of the
wide-angle bellows 1 fully out from between the camera standards.
Use the 455.46 wide-angle bellows 2 for 4x5
"/
19x12 cm pictures with 65 mm
lenses and very short extensions.
Camera backs
The SINAR models p2, c2 and
f2
include a metering back with probe holder
(462.16 for
4x5
"/9x12 cm, 462.17 for 5x7"/13x18 cm and 462.58 for 8x1 0"/
18x24 cm).
The 461.36 back
of
the 4x5"
/9x12
cm SINAR
f1
has no meter probe holder
and no lifting levers.
To
convert
to
the metering back replace the film holder
frame by the 462.96 frame with probe holder. If you also want the lifting lev-
ers, replace the model 1 screen frame by the model
2,
461.56.
Fitting the back on the camera
Open the locking lever at the top left (4x5"
/9x12
cm) or at the left and right
(5x7"/13x18 cm and 8x1 0"/18x24 cm)
of
the rear coupling frame, insert the
back at the base
of
the coupling frame, push home and lock (also see Figs.
8 and
9).
For upright and horizontal shots you can fit the backs
in
alternative
positions turned through 90°. (For horizontal shots position the meter probe
holder at the top, for upright shots at the left.)
