Mounting the camera
With the SINAR 411.21 rail clamp you can mount the SINAR cameras either
on the 516.41 pan tilt head or directly on a tripod.
• Turn the clamping lever A against the arrow
to
release it, fit the camera
and tighten the tripod screw C finger tight.
•
Turn
the clamping lever A
in
the direction
of
the arrow
to
secure the cam-
era firmly.
•
To
adjust the lever A use a coin
to
unscrew the centre screw. Remove the
lever and refit
in
the required position. Replace the securing screw.
• Slack off the knob B
by
a few turns
to
shift the camera along the rail for
balancing or
to
swivel it about the rail. Slack off by a few turns more to re-
move the camera altogether.
The rail clamp also takes the 519.
11
universal camera holder for mounting
35 mm and rollfilm reflex cameras.
Zero setting
Before starting operations set all movements
to
their zero ej:lgagement
points.

The spirit levels
To
read the spirit levels precisely, view with one eye centred above them.
You
see them correctly when each marking ring appears truly edge-on
as
a thin
line.
If the levels should eventually need resetting, you can
do
this yourself. Slack
off one screw completely and the second one slightly, realign the spirit level
and tighten the screws again.
The base rail
The camera outfit includes a 12
"/
30 cm 422.21 base rail, capped at both
ends and suitable for all SINAR cameras.
Rail
extensions screw
to
either end
to
make up any required length. A longer 36"/90 cm 425.21 base rail is avail-
able for constant use with long extensions.
Changing components
When switching metering backs, bellows, lens boards, etc on the coupling
frame, always push
in
such items straight from above and lock.
To
avoid light
leaks be sure to close the locking lever fully. But
don't
use force if the lever
is
hard
to
close - check rather that the component is correctly fitted.
