DEAR READER  I
We would like you to moke friends with your new Korot 36, ond we therefore invite
you to go corefully through this instruction booklet with us.
It will be well worth your while, for once you ore fomilior with the vorious operotions
                                                                                 36of your comero, you will soon toke successful pictures. The designers of the Korot
hove tried from the outset to moke the comero os fool-proof os possible. But remember,
otl the sqme, thot you ore hondling o precision instrument which needs o certqin
omount of core in monipulotion.
Devote o little time to your new componion right from the beginning. Stort off without
o film in the comero. Try focusing on vorious distonces, ond operote the ropid winder.
                                                                  confidence inAfter only o few ottemps, you will be surprised ot the feeling of
hondling the comero   so essentiol for toking octuol pictures loter on. Your Kqrot 36                     -                          of 35 mm. film for 36 or 20 or. 18 exposures 24x36 mm. uses the stondord cossettes

OPENING THE CAMERA
BACK

To open the comero bock, pull out
the smoll proiecting lotch (Fig. 1) in
the direction of the orrow. This is
eqsier if you press the bock ond
bgdy togelher'in the some wqy <ts
when closing the comero loter on.
No* open the bock, preferobly withthe cqmero lying lens down on
something soft.





                  FIGURE  I

Fold_up the hinged flop (Fig._2) over the sprockel wheel, ond you ore reody to iood
the film. When inserting the fresh cossette    preferobly in subdued light           pullout the rewind knob. When the cossette is- in position, push the knob bqck,--fullyturning
ii slightly ot the some time so thot it engoges the core of the cqssette spool (Fig.3).
Now guide the norrow tongue ot the beginning of the film into the slit of the foke-up
spool. Push in the film up to the second perforotion hole, hooking the smoll tooth of
the spool into the perforotion to onchor the film.

Turn the toke-up spool until the film is tout
(Fis. a).
Only obout o 3/e inch length of the Iwll
wi.dtb of the film should protrude from
the cossette.

Now you con close the comero
bqck. But first fold d,own the
hinsed flap in the middle of the film
trqck over the film. The film must be
properly centred between the sides
of the film chqnnel, with the per-
forotion holes engoging the teeth
of the sprocket wheel.
Close the bock by firmly (but not
forc.ibly) pressing  it ogoinst the body
until the lock engoges (Fig.5).

DEPTH OF FIELD. In oddition to the exposure, the operiure olso determines the
zone of shorpness in front of, ond behind, the focused distonce. Smoll opertures
(stoppinq down) oppreciqbly increose this zone of shorpness, giving whot is colled
                                                                                                                                                 isi;."i,i djpth of fie|il. The depth of field olso increoses the.forther oyoy the subiec-ff-rom. the cqmero. The operiure ond the distonce focused on ore therefore the two
foctors governing the defth of field. The resulting zones of shorpness for the vorious
settings ore given in the toble on poge 35.

GETTING READY TO SHOOT
THE COUPLED VIEW
AND RANGEFINDER

The view ond rongefinder
is very eosy to use. Hold
the eye close to the eye-
piece, ond get hold of the
focusing lever with the
second ond third fingers
of the left hond (Fig. 12).

 lf you pull this lever up or down, you will notice thot the imoge seen through the eye-
pi6ce is split horizontolly in the middle. As soon os the two holves ioin up, the comero  is
focused otthe correct distonce os shown by Figs. 13 qnd 14. The distonce is olso shown in
the smoll cut-out on the lens ponel. You con, of course, equolly well focus in the reverse
order: estimofe the distonce, set the lens, ond check through the rongefinder whether the
setting is correct. With horizontol shots focus on verticol lines, with verticol shots on
horizontol lines of the subiect.

THE PARALLAX ERROR. The finder shows o reduced imoge of the subiect qs it will
oppegr on the.film.. With close-ups, however, the view of the finder does noi correspond
exoctly with the film imoge, becouse the finder is situoted obove the comero lens. In
 proctice this is only noticeoble with subiects between 3 ond 6 feets owoy. To compen-
sote for.the.error, goinJ the c-omero slig.htl.y up for horizontol shots, ond'turn it sligjhtly
in the direction of the finder for verticol pictuies.

THE EXPOSURE
Just before toking the picture.check the setting of the operture, shutter speed, ond
distonce. Pull out ihe ropid winding lever once more os for <is itwili go, or described on
poge 12. This odvonces the film counter to No. 1, tensions the shutter, ond of the some
time odvonces the film by one frome.
     The rewind knob turns every time you odvonce the film, do not therefore hold it
      while winding.

HOR IZONTAL SHOTS
Fig.12 shows the best woy of holding the Korot 36. Grip the comero with both honds,
leovin-g the r.ight i.ndex._finger free to operote the releose button, while the finger tips of
