The Compur-Rapid shutter of the Retinettes has a light value scale and coupled aperture and speed settings. All the
aperture-shutter speed combinations obtainable at a given light value setting correspond to the same exposure. On
the Retinette II and IIB the light value scale is on the top of the shutter (left) together with the shutter speed
settings. The aperture settings are underneath the shutter. On the Retinette and Retinette I the aperture-speed
combinations are paired off opposite each other, and the light value scale is at the side of the shutter (right). To
alter the shutter-aperture combination, move the milled shutter speed ring until the appropriate aperture and speed
are opposite the index mark (on top and below the shutter on the Retinette II and IIB). See also page 10.
With a given light value (e.g. 11), setting a fast speed automatically opens the lens, while stopping down
automatically sets a slow speed to keep the exposure constant (right). To alter the exposure for different light
conditions, simply change the light value setting (left).
THE DELAYED ACTION RELEASE for self-portraits built into the Compur-Rapid (with or without light value scale) is
brought into action by moving the lever on the left of the shutter to "V". On pressing the release button with the
lever set to V the shutter goes off after a delay of approximately 12 sec., giving the operator time to take his place
in the picture. It goes without saying that the camera must be mounted on a rigid support, preferably a tripod.
After having released the shutter in the delayed action setting, the lever automatically moves back into the standard
position (X) to avoid the next exposure being inadvertently taken with the delay in action.
The shutter is flash-synchronized; for details, see page 59.
THE VERO SHUTTER of the Retinette IA has four speeds 1/30, 1/60, 1/125, 1/250 sec. and B, set by turning the
outer milled shutter rim to the required speed. Time exposures are made as described for the Compur shutter. There
is no delayed action.
THE PRONTO LK SHUTTER of the Retinette IB has 6 speeds 1/15, 1/30, 1/60, 1/125, 1/250, l/500 sec. and B, with
built-in delayed action and flash contact. Speeds are set by the outer milled ring, time exposures as for Compur
(page 9).
THE PRONTOMAT shutter of the Retinette IIA has no speed indication. In daylight set the sun symbol on the shutter
ring to the black index mark and use the exposure meter as indicated on page 59. For flash pictures set the shutter
to the flash-symbol (the shutter speed is 1/30 sec.) and proceed as for "X" flash synchronisation, page 67. For time
exposures set "B" on the shutter ring opposite the black dot. The aperture is then always f22. Use the "22" on the
right. The 22 on the left is for flash.
THE PRONTOR S or SV shutter of pre-1954 Retinette models has speeds from 1 to 1/300 sec. and is set by rotating
the milled ring which carries the speeds to bring the required speed opposite the index mark on the front of the
shutter.
This shutter (as well as the simpler ones fitted to some of these early models) requires tensioning separately before
every exposure. For that purpose push the tensioning lever (just behind the shutter speed ring) anti-clockwise until
it engages. The camera is then ready to shoot.
For time exposures proceed in the same way as with the Compur-Rapid shutter; again remember to tension the
shutter. There is no green scale of figures. The cable release screws into the release button, or (on models before,
1951) into a socket next to the button.
To tension the self-timer, pull the lever with the red dot on the left of the shutter (seen from the front) clockwise as
far as it will go. On some models this lever is also used for flash-synchronization (page 59).
