							Delayed Action
The deloyed ociion device (self-timer) should be iensioned by depressing ihe lever (9). This lever shouldbe operoted only ofter the shufter hos been iensioned. When the releose knob (18) is depressed, the mecno-nism siorts running ond will operote the shulter outomoticolly. When the lever (9) is depressed right downto its stop posiiion the deloy will be opproximotely l2 seconds. Belween the siop ond the iniiiol positionore nolches into which ihe lever con be sei for intermediote deloy periods. The self-fimer con be used witholl shuiter speeds from l-rlooo sec.
Time exposures from a tripod (Fig.li)
The CONTAREX is provided with o tripod bush (22) ond con be screwed to o tripod or o copying unit.This is necessory when moking lime exposures ond when long-focus lenses ore employed.The shutter should be releosed by meons of o cqble releose which con be screwed into the threod of thereleose knob (lB). The tripod bush (22) of ihe CONTAREX is countersunk into the comero body, whichensures perfect rigidity.
Exchanging the lens
The press-button (6) beside the lens should be depressed ond ihe lens turned in on onti-clockwise directionuntil ii stops: the red dot on ihe lens will then be opposiie the red dot (5) on the CONTAREX. In this positionlhe lens will spring outomoticolly from the boyonet mouni of rhe comero (Fig. l2).

To insert o lens, ploce the lens in lhe boyonel mounl
so thol the red dot on the lens coincides with the red
dot (5) on fhe CONTAREX. Turn the lens to ihe right
uniil it snops in. This will couse the press-button (6)
io spring out. The lens is then coupled ouiomoticolly
io ihe rongefinder. li does not motter whether the
lens iiself is set to infinity or ony oiher distonce,
or to whiclr operlure the diophrogm is set.
The CONTAREX lenses con be interchonged in full
doylight without fogging the film, but il is obvious
thot the opening in lhe comero body should beproiected from direct sunlighi.
A speeial case
The BIOGON t/4.5, 21 mm, which exlends deep into
the body of the CONTAREX, con be inserted only
when the mirr0r is in its raised positi0n.

The CONTAREX should be tensioned ond the mirror
swung upwords by depressing the smoll lug beneoih
ihe mirror (Fis. 13). Then the BIOGON f14.5, 21 mm
con be inseried occording to the red doi to red dot
rule. For sighting, fhe 2l mm viewfinder should be
used, which must be slipped into the occessory
shoe (4). The depth of field of the BIOGON f/4.5,
2l mm is so greot thoi it is sufficient fo guess ot the
dislonce. The depth of field ot f 15.6, when focused io
opprox. 6 fi., extends from opprox. 34 in. io infinily.
Inserting the BIOGON does not involve ihe loss of
o frome. When the BIOGON is removed the mirror
will reiurn to the viewing position oulomoiicolly. (For
iechnicol reosons it is impossible to use the deloyedqction mechonism for the first exposure ofter the
BIOGON hos been inserted.

The CoNTAREX speciol should be held in ihe left hond, with ihe lens pointing downwords. The lockingkeys (23) in ihe bose of the comero should be folded outwords wilh the righi hond ond iurned to the righiond ihe left respeciively. This unlocks the bock. With your left thumb push the bock of the comero down-words ond lift it off with the right hond.

Unloading
Exposed films in stondord commerciol cossettes hqve
to be rewound inio their cqssettes before beingtoken out. For this purpose the locking key (23) on
ihe comero bock (morked R) must be lifted ond
turned so thoi it points to the R (3a) (Fig. 22). Fold
oui the countersunk cronk (30) from the rewind disc (29)qnd turn ii in the direciion o{ the orrow (Fiq. 23\
until the film is completely rewound; this will beindicoted by o resistonce os the film leoves the toke-
up spool. After removing the bock, the cossette con
be removed. Porticles of film inside the comersshould be olwoys removed ol once.
