Minolta's Electromagnetic
Shutter Release: Key to an Incomparable
System of Super-8 Accessories
It is small, about the size of a matchbox, and
its function is very similar to an electric
switch since it performs a basic on-off
switching operation. Yet without the simple-
looking and uncomplicated electromagnetic
release which fits, and is interchangeable
with all three Autopak-8 D cameras, design
of the Minolta D system accessories would
not have been possible.
The magnetic release system differs basical-
ly from a conventional mechanical shutter
system insomuch as it activates the shutter
electromagnetically-and may be removed
and interchanged with other releases manu-
factured by Minolta for use with a wide range
of accessories. It performs the on-off switch-
ing operation for regular filming, of course,
but it also performs a more significant and
wide-ranging
control
function for the system
accessories , And herein lies its incompara-
ble vers atility,
Example: Removed from one of the D series
cameras and connected with a short exten-
sion cord, the switch becomes a convenient
remote-control unit. Or an "on-off switch-
ing" cable release hand-operated from dis-
tances up to 50 feet (15 meters) from the
-~
camera.
Connected to a special Minolta lntervalo-
meter (two are available), the switch permits
automatic time-lapse photography for a
variety of industrial, scientific, or basic
photographic uses.
Coupled with most cassette tape recorders
now on the market, the switch allows the
photographer to add sound to his film. Much
more, too.
So versatile is the mechanism and yet so
stable and positive is its electrical operation,
that one electromagnetic release can con-
trol two, three, even more than a dozen
Minolta D series cameras for simultaneous
filming, if such a complex operation would
ever be required. Radio-control operation of
the camera from a very great distance, even
in areas of high-rise buildings, is also made
possible by the shutter release mechanism,
as is the control of a
group
of accessories
simultaneously, such as timer, radio-control
tape recorder, strobe, etc.
The accessories that may be used with all
three Autopak-8 D series cameras are de-
scribed in detail on the pages which follow.
They give ample evidence of the virtually
un limited potential and promising new di-
mensions of 8mm photography, as per-
fected by Minolta.
