Setting the Film Gounter



                    Press the film releose button (14) ond of the some time push

Setting the Fitm Speed



Set the speed of the film looded in the comero on
 the film speed disc (ll) of the exposure meter. lf you
omit this serting, the merer moy indicsre incorrecr

the smoll stud to rotote the film speed disc (11) until
the blqck triongulor index points to the oppropriote
speed figure of the film in one of the two windows
(for DIN qnd ASA respectivety). ,For instonce use l2
for o 12/100 DIN film.
The film indicotor (21) on the rewind knob (20) is
olso o useful memory qid. Turn the serrqted ring
until the triongulor V mork points to the type or
speed of the film looded in the comero. The position
of this film indicqror does not qffect the exposure
in ony wqy.

Removing and lnsertinglthe Lens


                               The front component of the RETINA lens
                                        is interchqngeoble. To remove the ston-
                                dord lens, rotote it onti-clockwise qs for
                               os it will go, ond lift out of the shutter.
                       We recommend the use of the speciql lens
                                       contoiner designed for the stqndord lens
                                            for eosy chonging ond convenient storoge.

                          To insert the qlternqtive lens unit in the
                                   comero, ploce the red dot on the mount
                                    of the lens (18) opposite the red dot on
                                     the boyonet fitting (19), bs 'in the illustro-
                                            iion. Then turn the lens clockwise os for
                                  os it will go, to engoge the boyonet lock.
                               To remove the qlternotive lens unil ogoin,

The Large-size View'
and Rangefinder


The new lorge-size view- ond rongefinder
for q series of focol lengths greotly sim-'
 plifies photogrophy with the interchon-
geoble lenses. While previously on qcces-
iory multiple finder *os necesiory to de-
termine the field of view, the reflected
imqge fromes of the new multiple combi-
ned-view- qnd rongefinder instontly show
the correct field for tele ond wide-ongle
shots.
The inner brilliqnt frEme outlines the field
oreq for telephoto exposures (see top illu-
strotion), the outer brilliqnr frome the view
for wide-ongle shots (see bottom illustrq-
tion). You therefore see of the some time
which lens is the most suitoble one for
ony given subiect.
The morks on the imoge fromes se'rve for porol-
lox correction with neor subiects closer thon
8 feet (see poge 37).
