TOADING FIIM
l. Use 35 mm film in either blqck ond white or color, in 20 or 36 exposure cortridges.
Pull out the slide lock @ to open the bock cover.
2. Pull out the film rewind knob @, insert the film coriridge in the chomber @ ond ther
push in the rewind knob @.
3. lnsert the end of the film into the toke-up spool @; turn the spool in the direction
of the orrow qnd wind the film on the spool one full turn.
4. Roise the film rewinding cronk @; while holding the film corlridge, slowly turn the
cronk in the direction of the orrow ond toke the slqck out of the film. After moking
sure the perforotions of the film engoge the sprocket teeth @, close the bock cover.

SETTING THE FIIM SPEED
When the film hos been looded, be sure to set the
proper fllm speed. To do this, turn the film speed diol
@ ond set its indicotor on the number corresponding
to the fllm speed (ASA volue). The scole reodings with
red circles indicote ASA 32 ond 160.View original page 7Page 8 · Read text

PROCEDUR.E FOR. PHOTOGRAPHING
Since the Momiyo Prismot is o single lens reflex, everything you see through the viewfinder
will be on the film. Composing your picture is simpliffed.
l. Apply principles of good composition.
2. Determine the exposure.
3. Focus.
4. Finolly, press the shutter bution to toke the picture.
DETERMINING EXPOSURE
o; Selecting the shutter speed
Turn the shutter speed ring @ ond bring the
selected speed opposite the red triongulor
mork. The shutter speeds ore indicoted by
T, 1, 2,4,9, 15,30, 60, 125,250,500.
T indicotes "Time" (to be exploined loter).View original page 10Page 11 · Read text
b. Viewing the obiect to be photogrophed
The exposure meter pcinter @ will indicote the brightness of the obiect, os seen
through the viewfinder.
The operture ring @ moves the blue trocking indicotor
@ t when the trocking ond the exposure pointers coincide,
the exposure is perfecf. lf the trocking ond exposure
meter pointers do not coincide when the operture ring
is turned, chonge the shutter speed ond repeot the @ procedure.
Note l. The numbers indicoting the operture opening moy
not olwoys oppeor in the center of the operture ring
@. This does not, however, ofrect the picture foking
procedure.
Note 2. The exposure meter ot ASA 100 hos o working
ronge from EV4 to EVl7. This ronge is indicoted by
the oronge plote (working ronge indicotor @) which is
seen inside the finder. lf the exposure meter pointer @ is within the oronge section ot the lower side, the
oblect to be photogrophed is too dork ond the exposure
meter will not work.View original page 11Page 12 · Read text

USING THE EXPOSURE METER
The exposure meter is o refected light type; used properly, excellenf exposures con be
expected every time. Here ore some helpful hints on exposure :
Since this type expo3ure meter meo3ure3 the light reflected from the obiect olo
be photogrophed, it is necessory to toke o meter reoding os neor to the obiect os
possible ond ihereby exclude extroneous light which con qffect the exposure. The
pointers ore motched in this position ond the picture is token os for bock os good
composition demonds. Thus when the shulter is releosed lhe pointers inside the finder
do not necessorily hove to be in motching position.
Portroits
Approoch the subject ond toke o meler reoding off the foce. lf port of the foce
is dorker, meosure both light ond dork oreqs ond use the overoge.
Londscopes
To expose properly for londscopes, tilt the comero slightly downword, thereby restrict-
ing the omount of light from the sky offecting the meter reoding.
Bocklighring photogrophy
When moking o silhouette of on obiect, meosure the light from the bright port of
the bockground ond expose. When on obiect is to be photogrophed by bocklighting,
meosure the light from the obiect ot close ronge so thot the light from the bockgroundView original page 12Page 13 · Read text
will not influence the meter reoding. When the obiect ond the bockground ore to
be photogrophed ot the some time, first meosure the dork port of the obiect, then
meosure the light from the bockground ond use the overoge volue.
FOCUSING
This comerq hos on qutomqtic pre-set type lens ond on
instont-return mirror system which permits continuous
viewing of the subiect before ond ofter toking the
picture. Focusing is done by turning the focusing ring
@ right or left until the screen imoge becomes shorp
ond cleqr. The center of the ground gloss screen con-
!: ,i :toins o microdiomond prism ronge finder. When your !ee*qfi+$+!9
subiect is in focus, the imoge in the microprism will be
shorp ond perfectly cleor. lf your subiect is not in
focus, the microprism will breok the imoge up into mony
smoll diomonds, much like on engrover's screen. You con
focus on your subiect ot ony portion of the ground
gloss. This system permits ropid ond precise focusing
of oll distonces ond cqn be used with normol, wide
ongle ond telephoto lenses. www.butkus.usView original page 13Page 14 · Read text

DEPTH OF FIETD SCATE
The moximum shorpness of o lens lies in o plone ot the
distonce to which the lens hos been set. The shorpness
decreoses to the foreground ond to the bockground. This
ronge of shorpness is colled the "depth of field" ond depends
on the operture setting ond distonce to subiect focused on.
The smoller the operture setting the greoter will be the depth of field ond the neorer the
dislonce the smqller the depth of field.
To reod the depth of field scole @, ossume thqt the operture of your stondord lens
is set ot F-l I ond focused ot 5 m. You will notice thot F-l I is opposite the infinity
setting on the right side ond opproximotely 2.5 m on the left. Everything from
2.5 m to infinity will be in shorp focus.
The depth of field toble is o reody reference for other settings.View original page 14Page 18 · Read text

ADJUSTING DISTANCE FOR, INFRA.RED FILM
The lens is first focused in the usuil monner so thot the distonce focused on (i. e. oo) is
opposite the oronge triongle on the distonce scole. Now, simply rotote the focusing ring
so thot the selected distonce is opposite the red R. Distonce is now odiusted for infro-red
film.
PHOTOGR.APHING
Hold the comero firmly with both honds, pressing it ogoinst your cheek. Focusing con be
done with the left hond, the right-hond thumb on the film odvonce lever qnd the index
finger on the shutter releose bufton. ln this position, squeeze the shutter releose button
I @ gently. When using the exposure meter, moke sure thot the meter window is not
obslructed by your fingers.
MAKING TIME EXPOSUR.ES
With the shutter speed ring @ set on "T", pressing of the
shutter releose button @ opens the shutter which will remoin open
until the time releose button @ is pressed. The operture con be
set for ony volue in this instonce.View original page 18Page 19 · Read text
USING SELF-TIMER.
When the MXV selector @ is set to V, the self-timer i;
engoged. Pressing of the shutter releose button octuotes the
self-timer ond qfter o ten-second deloy, the shutter is outo.
moticolly releosed. The self-timer con be engoged before
or ofter film winding.
The threqded hole in the cenler of the shutter button is used
for o coble releose.
FIASH PHOTOGR.APHY
Chonging of the MXV selector lever @ to M or X, the respective contoct is mode. lf this
lever is set on V (self-timer), the contoct is X.
Function of M contoct 3
M closs (time log within 20 milli seconds) flosh bulbs con be used most efficiently on
this contoct; the exposure synchronizes perfectly ,p to l/500 second.
Function of X contoct:
This contoct is used when photogrophing with on electronic speedlight or when photo-
grophing ot l/30 second or longer, using F closs (time log within l0 milti second)
flosh bulbs.View original page 19Page 20 · Read text
www.butkus.us
When photogrophing with flosh bulbs, the synchronizing exposure time ronge is determined
by the kind of flosh bulb ond the kind of contoct (M or X). The operture opening is
determined by the distonce between the obiect to be photogrophed ond the guide number
of the porticulor flqsh bulb. For selection of the exposure time ond operture opening refer
to the instruction monuo! for flosh bulbs. ln this cose, the exposure time qnd operture
opening ore determined without reference to the exposure meter.
Besides the synchro socket (Germon typ.) @ on the front of the comero, on upper synchro
contoct @ is locoted on the occessory shoe. Use whichever is most suited for the type of
flosh equipment used.
ATTACHING OR DETACHING LENSES
Thiee kinds of lenses-stqndord (F-1.9, 48 mm), wide
ongle (F-3.5, 38 mm) ond telephoto (F-3.5, 100 mm)-
con be used with this comero.
