BATTERY LOADING
The built-in through-the-lens CdS exposure metering system of your
A-1OO operates on power activated by two 1.5V G13 silver-oxide
batteries, which are supplied together with your camera.
1. Remove Battery Compartment Cover (29) by unscrewing it
counterclockwise with a coin (Fig. 1).
2. Place the two batteries into the compartment with the plus @
side down, as illustrated in the battery holder of Battery Com-
partment Cover (29) (Fig. 2). Make sure that the batteries are
correctly placed. lf incorrectly placed. Exposure Meter Needle
(41) in the viewfinder will not move at all.
3. Replace Battery Compartment Cover (29) by screwing it
clockwise until it stops but do not force.
Tips for Better Results
* lf the shutter release button is pressed when there are no
batteries or they are worn out, the mirror will stay up and the
shutter cannot be released. To put the mirror back to its proper
position, turn the shutter speed dial to "X" or "8", and be sure to
insert new batteries immediately. lf you wish to take pictures
without using batteries, use "X" (1/9O sec.) or "B".
* Before loading, wipe off the surfaces of the batteries with a clean
and dry cloth to ensure they are free of fingerprints or stains.
* When your camera is not used for a long period, remove the
batteries and keep them in a cool, dry place.
* The batteries will last for about one year in normal use. We
suggest you replace them regularly once a year on your birthday
or sooner.
* The batteries may explode if disposed of in fire.

FILM LOADING
Your A- lOO is designed to accept any standard 35 mm color or black
and white film roll in cartridge. (12,20,24 or 36 exposures).
1. First of all, press Shutter Release Button (11)to see that the
shutter has been released. (Refer to "METER/SHUTTER ON-
OFF CONTROL").
2. Pull up Film Rewind Knob (1)until Back Cover (37) snaps open
(Fig. 3). Then, pull it out all the way to allow for insertion of the
film cartridge.
3. Swing open Back Cover (37land place a film cartridge into Film
Chamber (28) (Fig. ).
4. Push down Film Rewind Knob {llto its original position by turn-
ing Film Rewind Crank (2) clockwise or counterclockwise so that
Film Rewind Shaft (27) engages the film cartridge and that the
film cartridge is seated in place (Fig. 5).
5. Draw the film leader across the camera back and insert it into
one of the slits of Film Take-up Spool (36) (Fig. 6). To bring the
slit into a convenient position, rotate Film Take-up Spool (36) in
the direction of arrow with your finger.
6. Rotate Film Take-up Spool (36) by advancing Film Advance
Lever (13) to take up any slack in the film and check to see that
the film tip is firmly hooked onto Film Take-up Spool (36) (Fig. 7)
and that sprocket holes on the film are fully engaged on Sprocket
Teeth (23) (Fis. 8).
7. Close and press Back Cover (37) firmly until it snaps shut.
8. Advance Film Advance Lever (13) two or three times, after
depressing Shutter Release Button (111 sr.6 time. until the
number "1" is opposite the index line in Exposure Counter (14)
. (Fig. 9), because the first portions of the film can not be used for
picture taking as they have already been exposed to light and
two or three blank exposures should be made before taking your
first picture. Now it is ready for your first picture.

Tips for Befter Results
* Always load your camera in the shade or in a poorly_lit place,
never in direct sunlight or other bright light.
. * As you advance the Firm Advance Lever ('r3), the Firm Rewind
Knob (1) will simurtaneousry rotate countercrockwise indicating
that the film is advancing properly.
* when making brank exposures with shutter speed Diar (g)set at
"AUTO". set F-Stop Ring (22) to the smallest f_stop (the targest
lens opening) so that you can make next blank exposure quickly,
otherwise a slower shutter speed wiil be result which could be an
annoyance.
SETTING FILM SPEED
Each type of film, coror or brack and white, has its own sensitivity to
light. This sensitivity is assigned by a numerical value described as an
ASA rating (U.S.A. Standard) or a DIN rating (Europe and most other
countries) ln most cases, both ASA and DrN ratings are imprinted
on the film package, as weil as the data sheet packed with the firm
and the film cartridge itserf. The higher the firm speed rating, the
more sensitive the film is to light; that is, less light is required for a
proper exposure. The film speed, therefore, is an important element
in insuring that the through-the-rens metering system of your camera
determines the correct shutter speed and f-stop combinations for a
given lighting situation.
'1. Depress Fitm Speed Lock Button ( ) (Fig. 10) and rotate Film
Speed Dial (3) until the ASA number of your film is exactly op-
posite the index rine and crick stops. For exampre, if the firm rs
ASA lOO, make the correct setting at ,,lOO., (Fig. l1).
2. Take your finger off Film Speed Lock Button (4) to lock the film
speed setting in the camera.

Tips for Batter Results
* Each time a film with a new film speed rating is loaded in your
camera, the film speed mpst be set to assure accurately exposed
photographs.
* The scale represents the relation between ASA and DIN numbers
is illustrated on the inside of Back Cover (37) (Fig. 12).
METER/SHUTTER "ON.OFF" CONTROL
Film Advance Lever (13) controls shutter release "LOCK-UNLOCK"
to protect your camera from accidental shutter release when not tak-
ing pictures and Shutter Release Button (1 1)controls exposure meter
"ON-OFF" to avoid unnecessary depletion of the batteries.
1. When Film Advance Lever (13) is moved to "ON" position (Fig.
13), Shutter Release Button (11) is unlocked.
2. When Shutter Release Button (1 t; pressed half way down, the 'r electric circuit is switched on and Exposure Meter Needle (41)in
the viewfinder starts to move.
Tips for Better Results
* Whenever picture-taking is completed, be sure to move Film Ad-
vance Lever (13) to "OFF" position (Fig. 14).
* To prevent unnecessary consumption of the batteries, do not
) oress Shutter Release Button (11) often.
* The Film Advance Lever can be set at two angles in click stage
positions. Choose the one suitable for your own shooting style.

SETTING SHUTTER SPEED DIAL
The shutter controls the length of time the light is allowed to strike
the film. The speed at which the shutter opens and closes is measu-
red by the numbers on Shutter Speed Dial (8). In automatic exposure
operation, correct shutter speed is set automatically.
I Simply turn Shutter Speed Dial (8) until the desired shutter speed
is set opposite Shutter Speed Index Line (7).
O.......... "AUTO" stands for AUTOMATIC. Setting the dial at
"AUTO" makes the camera ready for automatic exposure
control.
@ The numbers 1OOO, 5OO etc. to 2 stand for 1/1OOO sec.,
1/5OO sec., etc. to 1/2 sec.
O .........The numbers'1 ,2,4. stand for 1 sec.,2 sec.. and 4 sec.
you@ ...... This button locks the dial at "AUTO" setting. When
move the dial off "AUTO", press the button and rotate the
dial.
@ . "X" stands for mechanical shutter for the speed of 1/9O
sec. This setting is used when the batteries have not suf-
ficient power or taking picture without batteries. Flash
photography is also possible at this setting.
@ . .. "8" stands for Bulb. The "B" setting is used for long night
exposure using street lights or electric signs as a light
source, or under poor lighting conditions when flash can
not be used. When set at "8", the shutter will remain open
as long as Shutter Release Button (11) is depressed
(preferably by a cable release).

Tips for Better Results
* Do not set Shutter Speed Dial (8) between marked speeds, but at
a click stop in accordance with indicated speeds only.
* Shutter Speed Dial (8) does not revolve between "AUTO" and
,,8,,.
* When Shutter Speed Dial (8) is set at "8" or "X", set the desired
f-stop and expose manually because metering with the built-in
exposure meter is not possible.
* When making extremely long time exposure at "8" setting,
remove the batteries to avoid unnecessary consumption of the
batteries.
SETTING APERTURE
The lens opening determines the amount of light entering the lens
and exposing the film. The smaller the f-stop (l/2.O, f/2.8 etc.), the
wider the lens opening and the greater the amount of light entering
the lens. The larger the f-stop ff/'16,t/11 etc.), the smaller the lens
opening and the smaller the amount of light entering the lens. As the
fens opening is moved lron l/16 to l/11, the amount of light entering
the fens is doubled. As the lens opening is moved froml/2.O tot/2.8.
the amount of entering light is cut in half (Fig. 1 5).
. Rotate F-Stop Ring (22) until the desired f-stop is opposite the
aperture index line (Fig. 16). Click stops are provided to prevent
accidental movement from the setting made.
Tips for Better Resutts
* lf necessary, you may set F-Stop Ring (22) between two f-stops.

Tips for Better Results
* At slow speeds(below 1/3O sec.), use a tripod or other firm sup-
port to prevent camera movement and blurred pictures. In
shooting with a telephoto lens, be careful to minimize the camera
shake especially. When using telephoto lenses, a good rule of
thumb is "use a shutter speed faster than 1/focal length of the
lens". For example, with a 135 mm lens, use a shutter speed
faster than 1/125 *c. Otherwise, a tripod is suggested.
* Coupling range of the exposure control for ASA lOO film is from
17). 1/2 sec. at t/2 to 1/1000 sec atI/'11 (EV3 -
* The shutter speed is automatically determined at any speed
within the range of approx. 8 sec. to 1/1OOO sec., according to
the lighting conditions of your subject.
Manual Exposure
Manual exposure setting is used when taking flash photography or
when you wish to preselect the shutter speed.
1. Press Automatic Exposure Lock Button (9) and move Shutter
Speed Dial (8) off "AUTO" (Fig. 21l,. Then, set the desired
shutter speed opposite Shutter Speed Index Line (7) by rotating
Shutter Speed Dial (8). Shutter Speed Indicator @2) in the view-
finder indicates the shutter speed you just set.
2. Move Film Advance Lever ('13) to "ON" position.
3. Hold your camera, look at your subject through the Viewfinder
Eyepiece Q4l and press Shutter Retease Button (11)tightly half
way down.
4. While keep pressing Shutter Release Button (1 t)natt way down,
rotate F-Stop Ring (22t- and align Exposure Meter Needle (4,|)
with Shutter Speed Indicator (42) (Fig. 22l'. lf Exposure Meter
Needle (41) goes above Shutter Speed Indicator (42), this means
"overexposure"; select a faster shutter speed or a smaller lens
opening. On the contrary, if the needle goes below Shutter
Speed Indicator (42), this means "underexposure"; choose a
slower shutter speed or a larger lens opening.

EXPOSURE COMPENSATION DIAL
The dial is used when exposure compensation (intentional over- or
under-exposure) is necessary in AUTOMATIC EXPOSURE operation.
In unusual lighting conditions. the desired effect or the correct ex-
posure will not be obtained in the final picture and exposure compen-
sataon is necessary.

it until the index line on the ring is opposite the corresponding
and click stops (Fig. 23). number (+2, + 1, -1, -2l.
When the light is behind ttre subjects
Set the dial at *1 or *2.
Spot-lighted subjects and dark backgrounds
Set the dial at -1 or -2.
Tips for Better Results
* When exposure compensation is unnecessary. be ,rr" ,o set Ex-
posure Compensation Dial (3) at "0".
* Do not set Exposure Compensation Dial (3) between marked
numbers, but at a click stop in accordance with indicated
numbers only.
VIEWING AND FOCUSING
Since you are viewing through the lens, there is no parallax
problem.....
What you are viewing in the viewfinder will exactly appear in your
picture. This enables you to determine the exact composition of your
subject before pressing Shutter Release Button (11). Even when you
shoot close-ups, there is no danger of accidentally cutting off a por-
tion of your subject. To assure the sharpest possible pictures, your
KR-10 has a three way focusing screen with diagonal Split-image
Spot (40). Microprism-image Band (39) and Fresnel field, and you
can select three way focusing according to your subject.
-11 -View original page 21Page 22 · Read text
www.butkus.us
1. Look into Viewfinder Eyepiece Q4l to compose your picture.
2. Split-image Focusing.....is helpful for the subject with either ver-
tical or horizontal lines.
Rotate Focusing Ring (19) until the split image in Split_image
Spot (40) forms a single image. When it is out of focus, your
subject is split into two parts (Fig. 24).
3 Microprism Focusing.....is good for the subject which lacks clear
vertical or horizontal lines.
Rotate Focusing Ring (19) until the image in Microprism-image
Band (39) appears sharp (Fig. 24).
4. You can also focus with any part of the area surrounding
Microprism-image Band (39). This is most useful when taking
pactures with ultra telephoto lenses or in close-up photography
with bellows unit. macro lenses or extension rings because the
other focusing aids may darken appreciably.
UNLOADING FILM
After the last picture on the roll of film has been taken, rewind the
film and unload your camera.
1. Press Film Rewind Retease Button (33) (Fig. 25).
2. Lift up Film Rewind Crank (2) and turn it clockwise until Film
Rewind Release Button (33)stops revolving and you feelthe film

T TAKING FLASH PICTURES
You can use a flash at night or in a dimly lit room as well as for l supplementary lighting in outdoor photography. The camera and
electronic flash wiil be fuily synchronized with the shutter speed at
"8", "X" and 4 sec. to 1/12S sec. Since proper flash exposure may
not be obtained by automatic exposure setting, always override
Shutter Speed Diat (8) from ,,AUTO,, setting.

In Cases where You Do not Use the XR Speedlite 240
Use a flash unit with a built-in hot shoe contact only because the
camera is not equipped with flash terminal for a flash unit with con-
necting cord. I
Exposure for Flash PhotograPhY
The exposure is determined by the guide number of the electronic
flash unit. The guide number repersents a relationship between the
light outprt of the flash and the speed of the film. Guide numbers for
electronic flash units are found in the technical specifications. Using
the guide number, you can determine the correct f-stop for a given
flash situation using the following formula:
F-stop : Guide number + Flash-to-subject distance
For example. if your flash unit has a guide number of 16 (m) or 52.8
(ft.) for the type of film you are using, and your subject is 2 meters
(6.6 ft.) from the flash unit as indicated on Distance Scale (2O) after
focusing, divide 16 (52.8) by 2 (6.6). The answer is 8, set F-Stop
Rins 1221 to 8 (f/8).
Tips for Better Results
* lf you are usrng an auto electronic flash unit with power ratio
control. follow the instruction sheets packed with the flash unit.
* Most electronic flash units have a built-in dial or exposure table
which enables you to quickly compute f-stops based on flash-to-
subject distances.
VIEWFINDER EYEPIECE CAP
When shooting with the self-timer or cable release where you will not
be viewing through Viewfinder Eyepiece Q4l at the time the ex-
posure is made, viewfinder eyepiece cap should be used to prevent
stray light from entering through the eyepiece and affecting the
automatic exposure system. (Fig. 27l..

:I USING SELF-TIMER .1
Your A- 1oo has a built-in self-timer which delays thp shutter release
about maximum of 10 seconds. This enabres you to incrude yourself
in your own picture and is also of benefit in taking close_ups or
photomicrographs where camera movement must be avoided.
1. First. advance Film Advance Lever (13).
2. Merely move Self-timer Lever (16) counterclockwise (Fig. 2g).
According to the degree you have moved it down, you can adjust
the operating time. For the maximum delay, move it untal at
stops.
3. Press Shutter Release Button (l 1) to start the self_timer moving.
Fi Tips for Better Results
* To clear the serf-timer setting. turn the lever back to its former
position with your finger. (Fig 29)
* You can set Self-timer Lever (.|6) firstly and then advance Film
Advance Lever ('13).
* The camera should be placed on a tripod or other firm support
when using self-timer.
* When using a tripod with a long thread length (more than 5.7
mm), be carefur not to forcibry screw in the thread further than
the depth of the socket.
* Shreld the Viewfinder Eyepiece (211 6, viewfinder eyepiece cap

CHANGING LENSES
To mount the lens on the camera
1. Mount the lens by lining up the red dot on the lens mount with
the matching dot on the camera mount (Fig. 3O).
2. Grasp the lens firmly around the lens barrel and turn it clockwise
until it clicks into place. (Fig. 31)
To remove the lens from the camera
1. Grasp the lens firmly around the lens barrel in one hand.
2. With the other hand, hold camera body and press Lens Release
, Lever (17) and turn the lens counterclockwise until it stops (Fig.
32). The lens now can be removed.
You can also change lenses without looking even in the dark by
means of Lens Locator Node (18). Line up Lens Locator Node (18)
with Lens Release Lever (17) and turn the lens clockwise for moun-
ting the lens. For removing the lens, press Lens Release Lever (1 7)
and turn the lens counterclockwise until Lens Locator Node (18) and
Lens Release Lever (17) line up.
Tips for Better Results
* Whenever a lens is mounted on the camera. make sure that the
lens is perfectly mounted, and clicks into position.
* Do not touch any of the internal parts or permit dust or dirt to
enter the camera body when removing or attaching lenses.
* Protect the inside of the camera by putting on the body cap
whenever the camera is carried or kept with the lens removed.
DEPTH OF FIELD
When you focus on a specific subject, an area in front of and behind
the subject will appear acceptably sharp in your picture. This area of
acceptable sharpness is called "Depth of Field". The depth of field is
determined by the f-stop you select and the distance from the in-
focus subject to the film plane. As you get closer to your subject, or
-16-View original page 26Page 27 · Read text
as you open your lens (for example. trom t/16 to l/2.9ll, the depth of
field becomes shallower. by stopping the lens down (for example,
trom f/2.8 to f /16]r, the depth of field becomes deeper. The depth of
field can be pre-determined in the following ways:
Depth of Field Scale
After you have set the lens opening and have focused the camera, the
area of acceptable sharpness in front of and behind your subject can
be also determined on Depth of Field Scale (2.|).
Locate on Depth of Field Scale (2.|) the two numbers corresponding
to the f-stop you have set on F-Stop Ring Pl;. The distance between
these two f-stops on Distance Scale (2ol will be an area of acceptable
sharpness in your picture. For example, if your lens is focused at 2
meters (6.7 ft.) aid you shoot at 16 ll/16), the area of acceptable
sharpness will be from 1.5 m (S ft.) to 3.2 m (10.7 ft.). by reading
Distance Scale (20) opposite the both sides of the ,,16,, numbers on
Depth of Field Scate (21) (Fig. 33).
INFRARED PHOTOGRAPHY
For infrared photography using infrared films, a correction of Distance
Scale (20) is necessary because "infrared light rays,, focus on a film
plane slightly behind that of "visible light rays,'.
1. Normally focus on your subject and note the camera-to-subject
distance gpposite the distance index line on Distance scare (20).
2. Turn Focusing Ring (19) until this camera-to-subject distance
setting is opposite the infrared index line. For example, if
Distance Scale (20) reads 5 m (16.5 ft.) after focusing, merely
shift the "5" scale to the "O" (red) position (Fig. 34).
Tips for Bettor Results
* Infrared radiation varies with the degree of infrared light rays in
the atmosphere.
