Hasselblad 500 C User Manual page 38

THE SUPER WIDE C has a Synchro-Compur shutter with speeds of 1,½,¼ 1/8, 1/15, 1/30, 1/60, 1/125,½50, 1/500 sec. and B. The
shutter is automatically tensioned on advancing the film by the film winding crank. It carries an exposure value scale and automatic
depth of field indicators. The base has fitting for instant tripod attachment. The release button is in the top of the camera body.
THE SUPER WIDE has a Compur shutter with speeds of 1,½, 1/5, 1/10,½5, 1/50, 1/100,½50, 1/500 sec. and B. The shutter has to be
tensioned independently. A knob is fitted for film transport and a depth of field scale is opposite the distance scale. The release button
is on the base of the camera front plate.
ACCESSORIES include the Super Wide viewfinder, flash gun bracket, magnifying hood, ground glass adapter, magazines, sheet film
adapter, quick tripod coupling, filters, and cases.
Shooting
1. Wind the film transport one turn to a full stop.
2a. Set the exposure value on the Super Wide C. The shutter rim carries a range of numbers engraved from 3 to 18. These are
exposure values for correct exposure. Each exposure value represents a range of shutter speed-aperture combinations of equivalent
effective exposure. To set the exposure value, slightly push back the serrated lever on the rim behind the exposure values and move
the triangular mark beside the lever to the appropriate exposure value (obtained from exposure tables or a meter) on the scale.
Intermediate exposure values, e.g. 10½, 11½, etc., can also be set.
2b. Set the exposure time and tension the shutter on the Super Wide. Turn the ring behind the front lens mount until its index points
to the shutter speed required. The engraved numbers 1, 2, 5, 10, 25, 50, 100, 250, 500, indicate fractions of a second and stand,
therefore, for½, 1/5, 1/10,½5 sec., etc. Then push up the shutter tensioning lever, which is situated between the aperture scale and
the flash socket.
3a. Select the aperture-speed combination of the Super Wide C by turning the milled shutter ring. Aperture and speed scales here
move together. The figures opposite each other represent alternative combinations corresponding to the exposure value set. Again only
the aperture and speed actually opposite the black central index line on top of the shutter are the ones in use. To set apertures and
speeds separately (e.g. for flash shots), adjust first the shutter speed and then the aperture on the exposure value setting ring.
3b. Set the Aperture on the Super Wide by moving the lever behind the aperture scale until its index points to the aperture selected.
4. Set the distance. Focus by turning the large milled ring on the rear of the lens mount to bring the required distance figure opposite
the index.
5. View the subject through the finder. Watch the spirit level through the prism. Perfect alignment is essential to avoid distorted
vertical and horizontal lines.
6. Release the shutter gently.
Special Controls
FOR TIME EXPOSURES set the index of the shutter speed ring to B (= brief time).
On the Synchro-Compur shutter of the Super Wide C the green figures represent full seconds corresponding to the aperture value
opposite them at a given exposure value. If you want to use one of these apertures, note the time opposite it. Set the aperture
separately by depressing the exposure value lever and turning the aperture ring. (Leave the shutter speed ring at B.) Then expose for
the time which was previously opposite that aperture value.
For time exposures use a cable release to avoid camera shake. On the Super Wide C this screws into the centre of the body release.
For long time exposures, where it is convenient to keep the release depressed, a time catch can be brought into action. The time catch
is the small lever with red spot in its top. Push this lever to the T position; the shutter will, on releasing, remain open until this catch
is pushed back to the O position.
On the Super Wide the cable screws into the cable release socket beside the release button. When not in use, the cable socket is
covered by a dust-excluding screw which has to be removed to insert the cable release. As well as a standard cable release, a time
lock cable can be employed which has a locking device on the base of the plunger. For long time exposures a cable release with time
lock is useful.
THE DELAYED-ACTION RELEASE built into the shutter releases at any speed set from 1 sec. to 1/500 sec. with 8½ sec. delay. It is
brought into action on the Super Wide C by moving the green lever on the left part of the shutter to V while pressing the small
protruding lock on the left at the same time. On the Super Wide model first tension the shutter, and then press the milled knob to the
left of the tensioning lever forward and tension again as far as it will go.
FLASH SETTINGS. For X- or M-synchronization, set the lever to the left of the shutter to X or M.
On the Super Wide C depress also the small lock protruding on the left of the shutter. This model is supplied with a cable bearer. This
is a hook with a ball at its end. The ball is pushed into the hollow on the side wall of the body-above the name plate. The protruding
hook will hold the flash cable to secure it to the flash plug.
