SELECTING THE SHUTTER SPEED:
The 12 numbers on the outer face of the shutter speed dial
are speed settings, and represent fractions of a second. For
example, (refer to Figure l), the number 125 on the dial (opposite
the engraved reference mark) represents L/L25 of a second.
Hence, the higher the number the faster the shutter travels
during an exposure.
when hand holding the camera for taking a picture, always use
a shutter speed of l/60 or faster if possible (see instructions
tor using the exposure meter). For speeds slower than l/60
second, the use of a tripod or other support is recommended.
with the shutter speed dial set at " B " the shutter will remain
open as long as the release button is depressed. When the
button is released, the shutter closes. For exposures utilizing
the " B " setting, the use of a cable release is recommended.
In the case of long exposures, a locking cabre rerease will allow
exposures of any duration. The cable release is attached to the
camera through the threaded receptacle on the top of the shutter release button.
shutter speeds may be changed before or after the film has
been advanced and the shutter cocked. The shutter speed dial
may be rotated in either direction when setting the desired
speed. However, as indicated by Figure J, the dial cannot be
rotated past the 1O0O position or the B position.
NOTE : When selecting a new shutter speed, never pull up on
the dial for the film speed settings (ASA/D|N) wiil be altered.

FOCUSING AND VIEWING:
The momiyo/sekor lOOO DTL is a Single Lens Reflex. This
means that you view the subject through the taking lens. Since
the same image is transmitted to the eye as to the f ilm, parallax
is eliminated. The subject is registered on the film exactly as
it is seen by the photograPher.
'Focusing (Refer to Figure K) the 1O00 DTL is made easier by
the micro diaprism focusing grid in the viewfinder. This is the
small round area in the center of the finder which exaggerates
the difference between the " in f ocus " and " out of focus " image.
By rotating the focusing ring (14) on the lens barrel, the micro
diaprism can be made to disappear. When this happens, the
image is in focus for both the eye and the film. For subjects
with irregular outlines, like wooded hillsides, the entire ground
glass area of the viewfinder may be utilized for focusing. In
any case (except with infra-red materials) when the image ap-
pears to be sharp in the finder, it will be sharp on the film.
When using infra-red f ilm, f irst focus the image as above. Then
note the distance as represented by the number which appears
opposite the footage index mark on the lens barrel. Rotate the
focusing ring until this number is opposite the small red mark,
and the lens will be correctly focused for inf ra-red photography
at that distance. This is necessary because infra-red film is
sensitive oniy to infra-red light rays, which focus on a plane
slightly behind that of ordinary light rays.

SETTING THE EXPOSURE:
There are two ways of determining correct exposure with the
momiyo/sekor Looo DTL. whether you use the'Spot or the
,I Average system will depend upon the type of picture you are
taking. ln either case, before taking the reading, set the Auto-
matic/Manual selector lever (21) on the lens barrel to the letter
il " A " so that the automatic diaphragm feature of the rens is
activated.
" SPOT " Reading:
The " spot " method of exposure calculation is especially valu.
able when the most important area of the picture is either much
fighter or much darker than the general picture area. or in
landscapes, where sky light would register a much higher reading
tlran trees or buildings at ground rever. such a situation would
cause under exposure if the subject were to be measured with
a conventional, averaging meter from the camera position.
Figure L " Spot " reading is also usef ul for subjects under insuff icient
lighting such as indoor shots or night scenes, because the ex-
posure meter needle reacts faster under these conditions thanI during average reading.
To obtain a spot reading, set the shutter at the speed at which
you wish to take the photograph. Move the Spot/Average se.

Looking through the viewfinder you will notice that the small pointer at the bottom of the field is now
on the letter " S " between the meter area brackets. These brackets outline the area of sensitivity, about
6% of the total picture you are viewing. Focus the lens so that the subject area is critically sharp.
Then aim the camera so that the bracketed area falls upon the most important part of the picture you
are about to take (Refer to Figure M). Make sure that the brackets do not include any part of the picture
that is either lighter or darker than the section you are reading (Refer to Figure N).

body until locking button (5) snaps up.) While pressing the film
advance lever toward the camera body as far as it will go, rotate
the aperture ring (16) (located on the lens) until the needle at
the right of the finder is centered between the open ends of
the reversed letter " C " (refer to Figure P). The exposure is now
set, with the selected area of the picture being correctly exposed.
You may now release the pressure on the advance lever and
make final composition changes before tripping the shutter. Figure O

Exposure Setting When Using Non-Automatic Lenses and Close-Up Accessories:
When using pre.set lenses, non-automatic extension tubes, bellows, microscopes, or other closeup acces-
sories, the lens diaphragm must be manually operated until the correct exposure setting is determined.
The lOOO DTL meter requires no special calculations or compensations to read correctly through exten'
sion tubes, bellows or other attachments. The meter reading must be obtained after final focus, since
exposure is influenced by distance between the lens and the film. Activating the meter and setting
the exposure is accomplished as referenced above
NOTE: You may reverse the above procedure if you wish to take a picture at a particular aperture for
any reason. In this case, instead of choosing the shutter speed first, select the lens opening desired
before taking the reading. Then, center the needle in the reversed " C " by rotating the shutter speed
dial.
DEPTH OF FIELD:
When a camera lens is focused to give a sharp image of a particular subject, some objects slightly
behind, as well as some objects slightly ahead of the subject focused on, will appear to be sharp. The
distance between the nearest and farthest objects, which are in focus, is called Depth of Field.
Depth of Field changes each time the focusing distance changes, becoming greater as the lens is focused
on points farther f rom the camera position, while decreasing as the point of focus becomes closer.
Other factors influencing depth of field are the focal length of the lens and the diaphragm opening at
which the picture is taken. The shorter the focal length and,/or the smaller the lens diaphragm opening,
the greater the depth of field for any given focusing distance, and vice versa.
l7View original page 20Page 21 · Read text
Proper use of depth of f ield can enable the photographer to utilize the principles of " selective focus,"
which often means the difference between ordinary snapshots and pictures of quality. For example,
the proper selection of a " sharp " zone of focus can eliminate an unwanted object in the background.
The same could be true for foreground objects.
When you wish to view the depth of field before taking a picture with the 1OOO DTL, set the lens dia-
phragm on " automatic ". Focus with the micro diaprism as explained before. Then press the film
advance lever as if taking a meter reading. This causes the lens diaphragm to close (e. g. stopped downl.
lf you have already taken the meter reading, the lens is now at the diaphragm opening at which the
picture will be taken.
The depth of field now appears in the finder exactly as it will be in the finished picture. By changing
the focus while the lens diaphragm is stopped down, you can select the area of sharpness in your picture.
When using non-automatic or pre-set lenses, the diaphragm must be closed manually, but the same
results can be achieved.
You may also determine depth of field by checking the scale (15) on the lens barrel (Refer to Figure Ql.
Numbers representing lens apertures appear at the near and far limits of depth for any given focus
distance and lens opening.
For example, if the standard lens is focused at 30 ft., one of the
lines representing t/I7 appears at the l5ft. mark. The other
f ine (again representinet/Ll) is at the infinity symbol. What this
means is that if a picture is taken with the lens focused at
30ft., and the diaphragm is set att/LL, all objects in the picture
between 15ft. and infinity will be in focus. This method is
extremely valuable when the lens diaphragm is stopped down
too far to allow enough light for the picture to be viewed through
the viewfinder and depth of field set visublly.

THE AUTOMATIC LENS:
The standard lens on the momiyo/sekor looo DTL is equipped
with a fully automatic diaphragm. This means that you may
view a scene with all light passing through a wide open lens,
but actually take the picture through a stopped down aperture
as indicated by the meter.
In order for the automatic features of the lens to operate, set
the Automatic/Manual selector lever l21l on the lens barrel on
" A " (Refer to Figure R). You will notice that after taking a
meter reading in the normal manner, releasing the pressure on
the film advance lever causes the lens diaphragm to open up to
its widest aperture. However, when you press the shutter release
button to take a picture, the lens automatically stops down again
to the aperture indicated by the meter. The diaphragm remains
stopped down only for the instant it takes for the exposure to
be made, and reopens itself immediately, so that the eye has
almost no sensation of having been " blacked out." Figure R
The automatic feature of your lens does not work when used on
non-automatic bellows or on extension tubes. In order to read
the meter in this case, proceed as explained in the earlier sec-
tion on Setting the Exposure.

CHANGING THE LENSES: f0
: CAUTION ! PLEASE READ THIS SECTION CAREFULLY BEFORE
.:i ATTEMPTING TO REMOVE OR INSTALL A LENS.T
t: To remove an automatic lens from your camera, first depress
:l the meter " OFF " locking button. Set the Automatic/Manual
I selector lever on the lens to " A ". Support the camera {Refer to
n Figure Sl body in the palm of the left hand with the lens pro.
jecting upward. With a firm grip on the camera body, use the
right hand to turn the lens barrel counterctockwise until all
threads have been disengaged.
To mount a lens on the camera, reverse the above procedure,
turning the lens barrel clockwise until it stops. Always be sure
the meter is in the " OFF " locking position, and that the threads
are properly engaged. No resistance should be felt when mount-
ing a lens. lf excessive pressure is necessary, remove the lens
completely, and inspect the threads for dirt or bther foreign
:i matter. Figure S
lf slight resistance is met when removing a lens, grasp the lens
barrel as close to the camera body as possible to avoid ac-
cidental damage.
Do not touch the reflex mirror after removing the lens. Dust
particles may be removed with a blower or a soft camel hair
brush.

HOLDING THE CAMERA: tl
Support the camera (Refer to Figure T) on the palm of the left
hand with the thumb and forefinger curled liehtly but securely
around the bottom and sides of the focusing ring. Place
the palm of the right hand against the end of the camera
body. The right forefinger automatically rests near the release
button, and the thumb is on the film advance lever. Bring the
camera up to eye level, and rest it against the forehead with
the viewing eye close enough to the viewfinder to see the com-
plete subject area. The forehead is now helping to steady the
camera. The left elbow should be held as close to the body as
possible.
You may compose the picture either vertically or horizontally
and the viewfinder shows the exact format of the picture. As
a general rule, the camera should not be held at shutter speeds
slower than 1/60 of a second. This becomes particularly im'
portant when using lenses of longer than normal focal length Figure T where it may be necessary to use even faster speeds to eli'
minate hand movement. At speeds slower than t/6O, use a
tripod or other support to eliminate camera movement.
The release button should be gently squeezed when taking a
picture. Never use a plunging or pushing motion.

SELF TIMER:l2
The self timer l2l provides a method of taking delayed action
pictures, thus allowing a photographer to be in his own pictures.
When the self timer lever is rotated clockwise (refer to Figure U),
it full travel of approximately 180 degrees, a delay of ten seconds
is provided before the shutter position is released. Shorter intervals
may be accomplished by rotating the lever for shorter distances
anywhere between 9O and 180 degrees. The self timer activating
button (1) is located behind the lever, and is visible only when the
timer is set for use.
Since the self timer operates independently of the shutter release
button, the camera may be operated in the usual way, with the
release button, even when the self timer has been set.
NOTE: lf the self timer lever is not rotated to at least 90 degrees,
timer will not function properly.
FLASH PHOTOGRAPHY: t3
The flash terminals, marked FP and X (11) (Refer to Figure V)
allows for a choice of flash synchronizations. The selection of a
terminal depends upon the type of flash used, as well as shutter
speed. The following table shows the correct combinations to be
used in various f lash situations. These combinations must be
rigidly followed to insure correct synchronization.

. When you have finished taking all the pictures in a cartridge, either 20 or 36, you must rewind the film
back into the cartridge.
To do this, push in the rewind release button (23) located on the bottom of the camera body. (Button
will remain inset without pressure until film advance lever is advanced a complete stroke.) Wind the
rewind crank (12) in the direction of the arrow until you feel the tension in the film lessen. This indi'
cates that the film has left the take-up spool. lf for any reason you are not sure that the film has
been totalty rewound back into the cartridge, continue to hold tension on the rewind crank and at
the same time advance the f ilm advance lever a full stroke. Trip the shutter and advance again. Repeat
this at least 3 times. lf you do not feel a tension or pulling on the rewind crank when advancing the
film advance lever, film has been completely rewound. Open the back of the camera and remove the
cartridge.
AVOID DIRECT LIGHT WHEN UNLOADING THE CAMERA.
