Depth of field - with all
SI~AR
models
After locating and focusing on the plane
of
maximum sharpness, stop
down the lens
as
far
as
necessary
to
extend sharpness at right angles
to
this plane. The simplest and quickest way
is
with the SINAR depth
of field scale:
- At full aperture focus on the most distant subject point required
sharp (i.e. focused with the shortest camera extension).
- Without changing the focus setting, zero the depth of field scale
(arrow against index).
- At full aperture focus on the nearest subject point required sharp
(i.e. focused with the longest camera extension).
- Read off the working aperture now shown on the scale (e.g. here
f/22) and set this on the lens.
-
Turn
the fine focusing drive 2 back through
two
lens stop intervals
on the depth of field scale (shortening the camera extension -
to
f/11
in
this case). This then yields optimum focus.
Further accessories
The SINAR COLOR CONTROL filter system
The SINAR COLOR CONTROL filter system 100 and 125 with over
200 different dyed-in-the-mass plastic filters plus polarising filters
meets all needs of present-day view camera photography. The filter
holder 100 holds up
to
three 100 mm filters at a time. A rapid clamping
screw secures adaptors
to
fit the holder
in
the filter thread
of
almost
any lens. The filter holder 100 further takes clip-on lens hoods
of
various sizes.
The filter system 125 comprises 125 mm filters held
in
the filter holder
1 (for one filter) or 2 (taking
two
filters) similar to the system 100 hold-
ers. Filter holders 1 and 2 also clip together and rotate against each
other. Further, the filter holders may be mounted on any SINAR stan-
dard with the bellows holder and rod or fitted
in
the multipurpose
standard.
SINAR exposure meters and shutters
Mounting exposure meters
A probe holder built into the film holder frame of the metering back
takes the metering probes of the SINAR exposure meters. The meter
itself is mounted on the probe holder via the 462.96.001 meter holder
plate.
• With the milling screw secure the meter holder plate
on
the probe
holder or
on
one of the side cover panels of the standard.
• Place the meter on the meter holder plate and lock
in
place.
• Release the lock on the probe holder.
• Insert the probe
in
the probe holder, with the SINAR logo facing to
the rear, and lock.
Automatic SINAR film holder and shutter coupling
SINAR backs carry a coupling socket for automatic shutter operation
via a cable linkage between the camera back and the shutter. This au-
tomatically closes the SINAR shutter on inserting a film holder
in
the
SINAR back. The connecting points are marked.
With the SINARICOPAL shutter
Once the 521.91 bayonet connector is adjusted, screw it tight
on
the
back and leave it there.
You
can then quickly switch automatic coup-
ling cables without readjustment. A connector can link
two
automatic
cables
to
bridge long extensions.
