SETTING THE FILM SPEED
Each type of film — color or black & white —
has  its own sensitivity  to  light. This sensitivity
is assigned a numerical  value described as an
ASA rating (U.S.A. Standard)  or a DIN rating
(Europe and  most  other  countries).  In most
cases, both ASA and DIN ratings are imprinted
on the film package, as well as the data sheet
packed  with  the  film  and  the  film  cassette
itself.
The  higher  the  film  speed  rating,  the more
sensitive the film  is to light that  is, less light  is       www.butkus.us
required for a proper exposure. The film speed,
therefore,  is an important element  in ensuring
that  the  through-the-lens metering systems  of
your  camera  determine  the  correct  shutter
speed/f-stop combinations  for a given lighting
situation.
Each time a film with a new film speed rating is
loaded  in the camera, the film speed MUST be
set  in  the  Film Speed Window  (8)  to assure
accurately exposed photographs.
To set the film speed:
1.  Lift up on  the outer  collar  of  the Shutter
   Speed Dial  (10) and rotate  it until the ASA
   number  or  representative  index  mark   is
   opposite the green index line.
2.  Release  the  collar  to  lock  the  film  speed
    setting in the camera.
The film speed range is from ASA 25-3200.

SETTING THE SHUTTER SPEED
The shutter controls the length of time light is
allowed to strike the film. The speed at which
the shutter opens and closes is measured in
fractions of a second that correspond to the
numbers on the Shutter Speed Dial (10). For
example 1000 is 1/1000 second, 125 is 1/125
second, 2 is 1/2 second, and so on. The number
"1" on the Dial represents one full second of FOCUSING THE LENS

When indoors in a well-lit room, 1/60 second
should be sufficient to record your subject,
depending upon the film you are using. Final
determination of a shutter speed setting should
be made based on the action-stopping needs for
your picture, i.e. the more action, the faster the
shutter speed required.

DEPTH OF FIELD
When you focus on a specific subject, an area in
front of and behind that subject will appear www.butkus.us
acceptably sharp in your picture. This area, or
zone, of acceptable sharpness is DEPTH OF
FIELD.
Depth of field is determined by the f-stop you
select and the distance from the subject in
focus to the film plane. As you get closer to
your subject, or as you open your lens (e.g.
from f16 to f2.8), the depth of field becomes
shallower. By stopping your lens down (e.g.
from f2.8 to f16), this depth or zone of
acceptable sharpness can be increased.
Another factor in depth of field is the focal TAKING THE PICTURE

provided by shorter focal length lenses is ideal
for "snapshooting" when there isn't time to
focus properly, as in fast action photography.
Shallow depth of field can be used to throw
distracting foregrounds and backgrounds out of
focus to add separation between a subject and
its surroundings.

A.  Specifications:
System:      Aperture-preferred      Automatic Exposure Control adapter.
Battery:            Toshiba 4G13 type 6V silver oxide  battery.
Operating range:   EV4 (F1.4 1/8)  - EV18 (F16 1/1000) with ASA100.
EE operating diagram:
                     F1.4       EV 4  - 11
                    F5.6       EV 8  - 15
                 F16        E V 1 1 - 1 8            (in case film speed is ASA 100)
B. Procedure of use:
1.  Insert the battery to the battery compartment (+ side face up).
2. Turn the speed dial of AEC adapter until the engraving of 1000 comes to the white indication.
3.  Set the speed dial of camera at 1000.
4.  Pull up the cock which lies on the top face of the adapter.
5.  Insert the adapter to the accessory shoe of camera.
6.  Lay down the cock as previously positioned.
7.  Engage the pin of speed dial of camera with the slot of speed dial of adapter.
8.  Fix the adapter by turning the lock-dial clockwise.
9.  Insert the plug to the socket.
C.  Operation:
1. Advance the film.
2.  Set the camera to the object which you want to take picture of, and press the release button half
   way down.
3. Then, immediately, the meter circuit is powered and one of the LEDs in the viewfinder will light.
    At  the same time, the motor of adapter starts running.  It runs just until the center positioned
   green LED lights and stops.


                                                                 13

4. When the green LED  lights,  it means that the exposure condition is correct. Now, you can press
    the shutter release button all way down.
5. When  either      or      red LED  light and  the motor  keeps  running, you should  rotate the
   diaphragm ring and choose another F stop until green LED lights.
6. When  red LED      lights,  it means overexposure, so you should rotate the diaphragm ring  to
    (right), in other words, to smaller aperture.
7. When red LED      lights,  it means underexposure, so you should rotate the diaphragm ring to
     (left), in other words, to bigger aperture.
8.   If the green LED does not  light though you have already set  to maximum aperture,   it  is out of
   EE range.  It is the same mean,  if the both red LEDs light at the same time.
