LOADING THE CAMERA
Use 35mm film available in 20 or 36 exposure cartridges. lt is recom-
mended to load and unload the camera in'subdued light. e.g. the shadow
of your own body and not in direct sunlight.
(1) Pull up f ilm rewind knob until camera-back pops open. Swing open
camera-back (Fig. 6).
(2) While rewind knob is still upraised insert film cartridge into chamber
with protruding end.toward bottom of camera. Press in film rewind
knob. lf it does not go in all the way,'.turn it until it does.
Fig.6 (3) Insert end of film into slot in take-up spool and engage perforations of
the film with the sprockets. Place thumb lightly over film on bottom
sprocket wheel and operate film advance lever until upper sprocket
wheel engages film perforations. When,advance lever, stops. free it
by depressing shutter release on top of" camera. Make sure that film
lies flat between guide rails (Fig. 7). Close camera back f irmly.
(4) Operate f ilm advance lever.ldepressing shutter release until figure "1"
appears in the exposure counter window. In this position the camera
is ready for the first exposure to'be made (Fig. 8).
To be certain that the film transports correctly. take up any film slack
.in the cartridge by turning the rewind crank clockwise till resistance,.is
felt. When advancing the film the rewind knob should turn counter-
clockwise. This is evidence that the film is loaded correctlv. lf it does
not, reload the film correctlv.

SETTTNG Fl[-M SPEED (ASA/DIN)
The ASA (or DIN) speed of the film is specified on the film box or tn the
instruction sheet packed with the f ilm.
Pull uo and rotate the outer rim of the shutter dial until desired ASA (DlN)
number of the film appears in the window on the top of the shutter speed
dial (Fis.9).
Also rotate film type reminder dial so that the film type inserted is aligned
with the index mark (Fig. 10). This will remind you of the type of film you
are using.
Some ASA (DlN) numbers are represented by dots only. The chart below Fig.9specifies the ASA (DlN) numbers.

DETERMINING CORRECT EXPOSURE
1. SHUTTER SPEED PRIORITY METHOD
This is the easiest and generally most useful method, to determine correct
exposure. merely follow the procedure outlined below.
(1) Select a suitable shutter speed. A guide for your reference follows.
a) Set 1/1000 or 1/500sec. to stop action outdoors, in bright sunshine.
b) Set 1.125O sec. for general purpose photography outdoors, in bright
su nsn I ne.
c) 11125 sec. outdoors on a hazy or cloudy day.
d) 1/60 sec. outdoors in deep shade.
e) 1/30 sec. for dimly lit scenes such as at dusk or indoors.
NOTE: A tripod should be used for shutter speeds of 1/30 sec. or
11 lower (1/30 - 1 sec. B). Fig.View original page 7Page 8 · Read text
(2) set the Aperture Ring to an intermediate position such as b.6.
(3) while loo.king,througtr the viewfinder focus the lens. and then gently
depress the Shutter Release Button. The diaphraqm blades williutol matically close and the viewfinder wiil appear- slightly darkened.
Slightly increase pressure on the Shutter Rele6se Butto-n ahd meterino
system will turn on, most likely resulting in a movement of the indicato"r
needle visible within the viewfinder.Fig. 12 (4) lf the indicator needle remains stationary at the minus position (Fig.
14), rotate the Aperture Ring counterciockwise until the needlb is
centered between the plus and minus signs (Fig. 12) indicating correct
gxposure. and then apply additional pressure 1o ttie Shutter-Release
Button to trip the shutter.
NoTE: lf the needle cannot be perfectly centered (Fig. 12) even after
completely rotating the Aperture Ring countercrockwije, a iower shui-
ter speed must be set by rotatrng the shutter Speed Dial clockwise.
/F\ lf the indicator needle rises to the_.plus position (Fig. 'uniil 13) indicatingFis. 13 overexposure, rotate the Aperture Ring clockwise it'is centered
between the plus and minus.signs (!ig. t2). Then take the picture by
Increastng pressure on the Shutter Release Button.
NOTE: lf the indicator needle remains in the plus position (Fig. 13)
even after fully rotating the Aperture Ring clockwise. a higher shuttei
speed must be set by rotating the Shutter Speed Dial counterclockwise.
NOTE: Correct exposure is determined by centerinq the indicator
needle between the plus and- minus signs (Fig. 1Z). Cdrrect exposure
can De set either before or after advancing th-e film
Fig. 14 2. APERTURE PRIORITY METHOD
Occasionally photographers wish to center the indicator needle not by rotat-
ing the Aperture Ring, but by rotatrng the Shutter speed Dial." This rhethod
is used to control depth-of-field and is easily acconiplished byfollowing the
procedure outlined below.
(1) Set the desired F-stop.on the Aperture Ring and focus the lens.
(2) Gently de.pre.ss the Shutter Release Button, without tripping the shutter,
and see'the indicator needle in the viewfinder. Accoid'ing to the posi-
needle, tion of the turn the shutter speed dial until tIe needie isFig, 15 Then centered. trip the shutter.

COUPLING RANGE OF THE BUILT-IN METER
The built-in meter of yotrr Argus Camera has a very broad range capable of
offering correct exposure in almost all photographic situation. However, if
the user tries to set a shutter speed which is beyond the coupling range of
the built-in meter, a red warning flag will appear between the plus and
minus signs (Fig. 15), indicating correct exposure cannot be obtained at
that shutter speed. To obtain correct exposure a higher shutter speed must
be set by rotating the Shutter Speed Dial counterclockwise until the red
warning flag disappears. For your reference, the chart below indicates the
lowest shutter speed that can be used at different film speeds (ASA's).
when setting a shutter speed lower than that indicated on the chart, the
red warning flag will appear.
ASA 1600 800 400 200 100 50 12
Shutter Sp'eed 1l3O 1115 118 114 112 1 1
FOCUSI NG
Turn the focusing ring first in one direction, then in the opposite direction
until the microprism disc in the center of the image in the viewfinder is
sharp (Fig. 17). The lens is now focused. The distance scale may also be
used for focusing; Estimate or measure the camera-to-subject distance in
feet or in meters, then turn the focusing ring sothatfigure representing that Fig. 17
distance is opposite the index line.
RELEASING THE SHUTTER
Hold the camera as steady as possible and press the shutter release slowly
and smoothly. When using slower speeds ranging from 1/30 to llsecond
and "B" (bulb) in poorly lit areas, useia tripod or other firm support to
prevent blurring of the picture.
BULB
The " B " setting can be used for long exposures at night, using street lights
or electric signs, or under poor lighting conditions when a flash unit is not
used.

UNLOADING THE CATUERA
When the red frgure " 20" or " 36 " appears in the exposure counter
window aligned with the index mark, the end of the film has been reached.
Take the following steps for rewinding the film into the cartridge.
(1) Unfold crank on rewind knob (Fig. 1B).
(2) Press in all the way the rewind release button on camera bottom (Fig.
1e)
(3) Turn rewind crank lever clockwise. Tension is felt as the film is re-
wound from the take-up spool into the cartridge. Stop rewinding when
Fig. 1B tension is released. Open camera-back (by pulling out rewind knob
all the way) and remove the film. Have film processed without delay.
DEPTH OF FIELD
A zone of the picture in front of and behind your subject will also be sharp.
The depth of this zone depends on the aperture selected. lf you wish to
know how much of an area will be sharp in the final picture. it can be
predetermined ,n two ways :
(A) Depth of Field Preview
Slide the AUTO/MANUAL lever to " M " (Manual). Set the lens to the
Fig. 19 selected aperture. This will enable you to prevrew the area of sharp-
ness in the picture before taking it.
(B) Depth of Field Scale (Fig. 20)
After setting the lens opening and having focused on your subject, the
area of sharpness in front of and behind your subject can be deter-
mined on the Depth of Field Scale. Locate on the Depth of Field Scale
the same two F numbers corresponding to the aperture you have set
on the aperture ring. The distance between these two F numbers on
the focusrng scale will be the area of sharpness in your picture.

www.butkus.us SELF-TIMER The self-timer permits the photographer to get into the picture. Place camera on tripod or other firm support (tripod socket is on bottom of camera). Get camera ready for exposure as usual. Push ciown self-timer lever (Fig. 2i). Depress shutter release to start self-timer. Exposure will be made approxi- mately 8 secbnds after the release has been pressed. FLASH PICTURES Most types of flash bulbs and also electronic flash can be used for flash Fig.21 p ictu res. When using flas,h bulb No.5, 58,25,25B, M5, M58, M2, M2B, AG1, 6. 68, 8, connect the flash cord to flash socket " l/1". When using electronic flash or Stt4 flash bulbs, connect the flash cord to flash socket "X" (Fig. 22\. When using Nos. 5,5B, M5, and M5B flash bulbs as well as electronic flash, Nos. 6, 68, 8 flash bulbs shutter speeds from 1/30 to 11125 sec. are recommended. When using Nos. M2, M2B, AG1. AG1B, SM flash bulbs shutter speeds from 1730 tq 1/50 sec. are recommended. Cordless flash units are slipped into the accessory shoe on the top of the camera. The accessory shoe may Fig.22 also be utilized for a flash unit having a synchro cord. CHANGING THE LENS A 55 mm lens is the proper focal length for general purpose picture taking. Any Argus telephoto and wide angle lens with screw mount (42il can be used. To remove the lens, grip the lens with one hand and the camera with the other, turning the lens counterclockwise untrl it is removed.
