Hasselblad SWC/M - Mode Selector and Release Controls; Understanding mode dial settings

MODE SELECTOR (Fig. 51)
'The mode dial has five settings governing the
camera release mode.
О = Normal mode. When the shutter has
been triggered and pressure on the shutter re-
lease relaxed, the film is advanced, the
between-the-lens shutter is cocked and the
mirror is returned to the focusing position.
S = Pre-release. Certain mechanical func-
lions are pre-released in this mode, leaving
only operation of the between-the-lens shut-
ter when the release button is pressed. This re-
duces camera-induced shake even further and
reduces to a minimum the time elapsing from
the moment the shutter release is pressed until
the shutter actually operates. The mode selec-
tor automatically returns to the O mode after
each cycle.
RS = Pre-release repeat. Operation is the
same as in the S mode but the camera remains
in the S mode after shutter release.
A = Automatic. The camera makes continu-
ous exposures as long as the triggering im-
pulse is supplied and unexposed film remains
in the magazine. The sequential exposures in
this mode are at a rate of about 1 frame/s.
The A setting cannot be used with shutter
speeds slower than 1/15 s.
AS = Automatic pre-release. The same oper-
ation as in the A mode, but the camera re-
mains in the pre-release mode after every
exposure sequence.
