Your new Argus C20 is a precision camera with
outstanding ease of operation. Its many fine
features put it in an advanced class, yet the
Argus system of Color-matic settings will give
you beautiful color slides or black-and-white
pictures your very first try.
This book provides detailed information on
the features of the C2O and how it operates.
Familiarize yourself with the lens, the shutter,
and the rangefinder before you Inad the fi,rst roll
of fiIm. This will acquaint you with the camera
and prevent your missing an important picture
through lack of familiarity with its operation.
Because Argus products are constantly being
improved, minor changes in the appearance of
this product may not be included in this
instruction book.View original page 3Page 5 · Read text

The shutter speed setting controls the length of time
the shutter is open when the picture is taken. Num-
bers on the scale are fractions of a second and have
"click stops." They are selected by turning the
knurled ring to bring the index mark directly in line
with the desired number. Always set th.e indet mark
on th.e nurnber.
When the index mark is set on "8", the shutter will
remain open as long as the shutter release is held
down. This is for time exposures. A tripod and cable
release are recommended to prevent

The CzO lens is automatically focused when the rangefinder
images are lined up as shown on the opposite page.
T.he left eyepiece on the back of the camera is the rangefinder
window. To use the rangefinder, hold the camera as illustrated
and turn the focusing ring with the thumb and forefinger until
the images are lined up. Then look through the viewfinder window
to take the picture.
The camera can be held horizontally or vertically. f[ustrations
at right show how to hold it comfortably. As you become ac-
quainted with the camera, you may develop your own techniques
for holding and focusing.
It is usually best to focus on the main subject in your picture.
Ffowever, more than the main subject will be in focus in the
picture due to what is called a range of sharp focus. This range of
sharpness increases with smaller aperture settings and greater
camera-to-subject distances. It decreases with larger aperture
settings and as you move closer to the subject.View original page 8Page 9 · Read text

Color-matic settings on the aperture, distance,

Color-matic settings can be used for the shutter

On your C20, the aperture, shutter speed, and distance scales work together to
properly expose the flm and provide a sharp, clear picture. The right combination
of shutter speed and aperture opening always provideo correct exposure for the
picture you are lqldng.
Color-matic settings provide best erposure in bright sunlight with average
slrbjects; however, other settings are necessary for other light conditions. Faster
shutter speeds with larger aperture openings can be used when you wish to stop
action. Smaller aperture openings may be used for a greater range of sharp focus.
"ffi,, For example, an average exposure in bright sunlight might call for l/1fi) of a
W"co:rd' at f/8. A faster shutter speed can be used if some compensation is made
in t&e aperture setting. If you change the shutter speed from 1/100 to L/2OO of a
second for erample, the shutter is open only half ae long- To compensate for this,
move the aperture setting ftonf /8 to f /5.6 (one stop) and this provides an opening
twice as large. In this way you compensate for the faster speed of the shutter.
In the same way, a shutter speed decreased from 1/1OO of a second to l/5O of a
second would require the aperture opening to be changed from f/8 to the smaller
opening qf f/LL (one stop). Any of thcse combinqtions will providc the same erposure.View original page 10Page 12 · Read text

Shoothead-onto stop action.
Beautiful outdoor pictures and color transparencies are easy with
the CzO. Check the picture composition through the camera
viewfinder before snapping the shutter. This will always result
in pictures with more interest, and you will be certain that you
are not cutting off an important part of the subject. Try framing
the scene with some nearby object in the foreground, and include
people when you can to add human interest. Watch for that
unusual angle from which to take the picture, or try a close-up
using a neutral background to place emphasis on the subject.
The outdoor exposure guide on page 12 will help you to select Scenesmakefine colorslides.
the correct aperture and shutter settings for different light
conditions with auerage outdoor picture subjects such as nearby
people, gardens, houses, or light and dark objects in about equal
proportions. Close aperture one stop from chart setting for light
subjects (distant scenery, marine, beach, and snow scenes, light
colored subjects dominating). Open aperture one stop more for
dark subjects (dark foliage, flowers, animals, and buildings).

into side of camera. fnsert flashbulb by pushing it in as far as
it will go. Do not twist flashbulb after it is in.
Since the intensity of light changes with the distance from
the subject, it is necessary to change aperture settings when
camera-to-subject distances change. The guide number system
on page 14 will help you to determine correct flash exposures.
Guide numbers are given in the table for combinations of
popular films and Sylvania flashbulbs. With other make flash-
bulbs consult the flashbulb carton. Divide the appropriate guide
number by the number of feet between your camera and the
picture subject to obtain the correct aperture setting.

it with lens tissue. Use lens cleaning
fluid only if it becomes absolutely necessary.
Working parts of your CzO contain fine threads,
tiny screws, and sensitive adjustments.
Never force any parts of the camera to work if they resist.
