Mamiya RB67 - Shutter Operation; Setting Shutter Speed and Aperture; Cockling and Releasing the Shutter

• Shutter Operatio~
1. Align the scales on the shutter speed
ring (28) and the aperture ring (27)
with the red dot on the center of the
lens barrel.
Always set the shutter speed to the
click stop position. In-between shutter
speeds cannot be used. However, the
fully automatie diaphragm can be set at
full and half click stops.
If the shutter speed is changed , after
cocking the shutter, do not turn the
shutter speed ring rapidly .
When not using flash, the M-X selector
lever (24) can be set to either M or X;
however, never set the lever between
M and
X.
When switching the M-X selector , move
the
lever to the right or left, while pressing
the
lever against the lens barrel.

2. Press down the shutter cocking lever
(1). The shutter in the mounted lens and the
mirror
in the camera body are cocked simul-
taneously.
The lever will return to its original
position by seit-action.
If the lever is depressed by 45 ° or
more (but not fully)' the lever will remain
there without returning to its original
position.
Once the shutter is cocked, the cock-
ing lever will not move until the shutter
is released by pushing the shutter re-
lease
button. Therefore , when the cock-
ing lever will not move, you know the
shutter is cocked.
3. To release the shutter, press the
shutter release button (9). If the shutter
and the mirror are not cocked, the shut-
ter release button cannot be pressed.
The socket inside the shutter release
button is threaded so that a cable re-
lease
or a self-timer can be easily at-
tached.
By turning the shutter release lock
ring (8) and aligning the index mark
with the orange-yellow dot on the camera
body, the shutter release button cannot
be pressed. This device prevents ac-
cidentally releasing the shutter while
carrying the camera in its case.
NOTE:
If the slide lock (17) of the revolving
adapter is not pushed fully in or out ,
you
may not be able to press the shutter
release button. Always shift the slide
lock until it comes to a halt.
Time Operation
By setting the shutter speed scale on
T (time)
and releasing the shutter, the
shutter will remain open for an extended
time exposure. To close the shutter,
turn the shutter speed ring toward the
1 sec. marking or press down the shut-
ter cocking lever about 30 ° ; however,
do not move the shutter cocking lever
until just be fore closing the shutter.
