.  OPERATION INSTRUCTIONS ARETTE Bx
    The ottroctive minioture comero ARETTE will become your relioble componion
    soon to be indispensoble. Jusi o few monipulotions ore necessory to become
    fomilior with the comero ond to obtoin successful pictures ot oll the time.
    The following 4 feoiures of the ARETTE will eose your operotion considerobly:
   SAFE in your honds by meons of the NEW SHAPE.
   SAFE froming bosed upon o bright ond occurote LUMINOUS FRAME
   VIEW FINDER.
   SAFE in operotion by the relioble ropid lever wind ond shutier with EXPOSURE
   VALUE SETTING.
   SAFE timing ond color-toning by meons of the built-in EXPOSURE METER with
   READJUSTING INDICATOR.

TOADING OF CAMERA
The ARETTE tokes the perforoted  minioture film (35 mm),
ovoiloble in the stondord cossette for 2A or 36 exposures
(24X36 mm).
To open the comero bock the two locking butions ore to be
pressed ogoinst eoch other by thumb ond irrdex finger of your
right hond. The topered end, overlopping from fhe cosseite hos
to be folded through the middle of the third perforofion hole
(A) thot when inserting ihe folded end irrto the slot of the
spindle the red hook will feed the third perforotion hole. This
ovoids ony pulling out of the film when winding up.
The film cortridge hos to be inserted into the cossette chomber
of the comero ofter the rewinding knob hos been fuily pulled
out. Hoving inserted the cossette the rewinding knob hos to be
pushed in ogoin ond by turning the knob in the direction of the
orrow the film is stroightened ond lies on the focol prone. Now
the comero bock will be closed. Before toking the first picture
the film should be odvonced os described on poge 6.
                                                                  5

FITMTRANSPORT
For sofeiy tronsport the ropid lever wind (26) must be turned until the stop. At the
some time the film will be tronsported, the shutter cocked, the exposure counter
operoted ond ihe double exposure lock put in. The reverse motion of the ropid lever
wind works outomoticolly.
EXPOSURE COUNTER
The film which is pre-exposed by inserting some must be removed by 3 blonk
exposures (tronsport ond releose) in order to hove unexposed film on the focol plone
for the first exposure. The exposure counter (27) will be put into its bosic position "0"
                               by pressing ond turning to the left or right.
                                   Accurote counting is only guoronteed by in-
                                       serted film. Moreover  it shows - before snopp-
                                       ing - which picture is reody for exposure.

DIN/ASA.ADJUSTING
The DIN/ASA disk (7) must be odiusied by meons of
the operotion knob (9) in occordonce with ihe DIN
or ASA vqlues indicoted on the film pockoges.
The setting of the film sensitivity hos to be ochieved
on the film sensitivity indicotor (10), ioo. The indi-
cotion "NEG" ond "POS" refers to negotive respec-
tively positive color films ond the block/white/block
field refers io block ond white film.

HINTS FOR EXPOSURE READING AND ADJUSTMENT
Oneof the most imporiont foctors  in obtoining successful pictures is thoi the omount of
light will foll on to the film which  resulis ihe correci holf tone effect of the film. lt is
simultoneously whether this light volume is obtoined by..less light over o longer or
more light over q shorter period.

www.butkus.us
The built-in exposure volue meter will reod exoctly the omouni of light being reflected
from the subiect onto the lens.
The principle of modern exposure volue reoding is to express the omount of light
under considerotion of the film sensitivity in o figure, the so-colled exposure volue.
This exposure volue figure will be obtoined from the exposure meter ond the
shutter ot the comerq hos io be odiusted occordingly. The mechonism of the shutter
iokes core thot by meons of the engoged exposure volume olwoys the correct omount
                            of light will reoch the film. Usuolly long exposure
                              times coll for smoll diophrogms which ollow light
                              through o smollopening onlywhereos short exposure
                                times increose the opening of the lens.

                                    This         excellent detoiled negotives.
                            The coupling of exposure iime ond diophrogm in the
                              exposure volue shutter qllows o quick ond occurote
                                  oction. This is especiolly importont with color films

to obtoin sufficieni results.

PHOTOETECTRIC EXPOSURE METER

The indicotor (4) engoged by the light reflected on
the photo cell (3) con be eosily reod from obove ot

to the comero lens.
The film sensiiivify hos lo be odiusted by.the operotion knob (9) of the exposure

SHUTTER
The ARETTE is equipped with the PRONTOR SVS shutter including exposure volue
odiustment. No concern hos to be token obout the cocking of the shutter os this is

ln order to odiust the shutter in occordonce with exposure volue engoged by the
exposure meter the interlocking lotch (13) must be pressed down. Thus results

volue scole (11). Also the time setting ring (14) or both rings (14 ond 15) con be
odiusted ot the some time by pressing the interlocking lotch. The exposure volue

RETEASEil
I   To releose the shutter the releose knob (1) hos io be pushed down by index finger
     until the shutter clicks. Avoid ony sudden ond pulling movements os they ruin your
     pictures. For time exposures set time setting ring (14) of "B". The shutter remoins open
      until you will releose him. Coble releose should be screwed into the socket. For long
    exposures  it is odvisoble to use o coble releose with fixing screw.

   SEIF TIMER
    The self timer is o help in mony respects  i. e. when the comero user desires to oppeor
    on the picture or when o time exposure might be .obtoined from on insecure position
    which might result o shoked releose.
    The self timer con only be operoted with cocked shutter. Slide synchro switch lever (19)

FITM REWIND
At the end of ihe filmtronsport o cleor obstruction will be noticed when trying on

pulled out the exposure counter will indicote onother figure os the expected number
20 or 36.
Before opening the cqmerq bqck the film musl be rewound into its cortridge.
Operote releose lever (23) for rewind mechonism. Rewind knob (24) will come out

Lightening of flosh should be effected only by fully opened shutter. This colls for the
correct position of synchro switch lever (19). For better illustrqtion ore given some
hints on poge 19.
Lever (19) must be set ot "V" when using the self timer. Exposure will be effected with
o deloy of 8 seconds. The flosh will olwoys be lightened by the rules of the "X"
