THE DOUBLE EXPOSURE LOCK
The
Karat
36 contains
a clever
locking mechanis,!!
which
prevents
double exposures
and blank
frames. After every exposure
the
release button
is
locked, and only
works
again after
the film has been advanced by one frame by means of the winding lever.
THE
SHUTTER
The movement of the winding lever
at
the same time automatically tensions the
Compur
shutter.
The
shutter
speed
should
therefore be set beforehand.
This is essential for the
'10
00
second setting. Once the shutter
is
tensioned, the resistance of the
built·in additional spring
is
very hard to
overcome
when setting
the
shutter speed to
'
/0 00
second
.
To
set
the
shutter speed,
turn the outside milled
ring with
the figures
1
2 5 10 25 50
100
250 500 on it
(Fig.
10). These numbers signify fractions of a second; for instance,
2
stands for
a
112
second,
50 for
1/
50
second,
and so
on.
Set the required
speed
against
the black triangular index mark on the neighbouring milled ring
(1
/
50
second in our
illustration).
The
"B"
setting serves for time exposures with a tripod.
All the scales of the Karat 36
can, incidentally,
be
read
off from above.
The Synchro-Compur shutter of the Karat is speed synchronized, and carries a flash
socket for connecting a flash cable, as well as a synchronizing lever with two positions,
"X"
and "M"
(see
illustration on page 16). This allows the use of all types of flash at
the fastest shutter speeds. How it works is described in detail
in
the special section
on Speed Synchronization on page 26.
