GENERAT DESCRIPTION
  The MAMIYA METRA Model 2 is the latest development of the famed
MAMIYA METRA series of 3S-millimeter miniature cameras, acclaimed by
discerning photo-enthusiasts  r,r-ho prefer the greater freedom of choice afforCed
by dispensing with mechanical cross-coupling of the built-in exposure meter
to the exposure controls. The new improved exposure meter gives the whole
range of essential light values in a single sweep. There is no need for at-
tenuation at high intensities, and shifting of the meter scale.
  Read all instructions carefully before trying out the functidns of  this
precision camera.
  Cocking Action Holding camera in both hand, hook right thumb on
cocking lever (1), and turn it through an arc of 180' till  it comes to a stop.
This action advances the film one frame, cocks the shutter mechanism,
moves the exposure counter up one step, and turns the cock indication red.
At completion of stroke, the cocking lever will spring back to its original
position. It is preferable to cushion this return action with the thumb.                          www.butkus.us

Once the camera is in cock, the cocking lever cannot be operated.
  Automatic Aperture control  with the SEIKOSHA-MXL shutter of the
MAMIYA METRA Model 2, the aperture settings are automatically regu-
 lated by the shutterspeecl control. Consequently, once the proper light value
 is set on the LV scale, correct exposure of the film is obtained regardless
of changes in shutterspeed.
   Electronic Exposure Meter The built-in exposure meter is a specially de-
signed, high-precision instrument which gives accurate measurements of the
light value of the subject-matter. No mistakes in exposure can be made
once the light value indicated by the meter is transferred to the LV scale
on the shutter housing.
  Coupled  Rangefinder
Moving  the   focusing
lever (4) back and forth
causes the  lens-shutter
assembly to move in and
out, and this movement is

transferred to the rangefinder system. This coupled action can be seen by
the changes that occur in the double-image focusing spot'at the center of
the viewfinder field. Sight subject through eyepiece (10), and adjust focus-
ing lever so that overlapping images of subject in the focusing spot merge.
At this point the subject is in proper focus, and the distance is indicated
on the distance scale (21). When focusing lever is at lower end of its arc,
focus is set at infinity (oc), at 1 meter (approximately 3.3 feet) when at the
other end.
  Film Rewind ro return exposed film from take-up spool (6) into safety
cartridge or special MAMIYA cassette, press sprocket release button (23) to
release sprocket (7) from filmwind mechanism. Erect rewind crank (3)
and turn in  direction of arrow mark (clockwise) to take up exposed
film into the cartridge. Do not touch sprocket release button (29) or
operate rewind crank (3) while there still remains unexposed film  in
the camera.
  The depressed sprocket release button will spring out automatically upon
operation of the cocking lever,www.butkus.us

spool properly, turn rewind crank slightly until
 it snaps home with a click
  2- Pull out about four inches of film, and.fold
 about a quarter inch of the end inward toward
 the emulsion (non-glossy) side (FiS. 2).
  3. with  tip of thumb turn take-up spoor
 (6) until slit on spool appears in convenient po-
sition. Insert folded end of film in slit of take_
up spool, and wind on to spool at least one turn,
seeing to  it that the sprocket teeth properly
engage the film perforations (FiS. B).
  4- rlolding the firm in position on the spro-
cket (7), turn rewind crank (3) clockwise to take
up all slack (Fig.   ).
  Turn take-up spool slightly with thumb to see
that film is played out properly from the cart-
ridge     or cassette, and that it meshes with the  www.butkus.us

sprocket (7).
  5. close backlid, and push down backlid catch (5). If too much film is
wound on to the take-up spool during loading, and the perforations on
both sides of the film are engaged by the sprocket, one or two frames may
be wasted.
  when the backlid is closed, the exposure counter indicates " srART."
  6. Keeping lens covered, operate cocking lever (1) and shutter button (2)
to take two blank shots. Upon working the cocking lever for the third
time, the exposure counter (11) will indicate " 1," and the camera is readv
for the first picture.
  7. When film is being advanced and taken up properly by cocking action,
the rewind crank will revolve in counterclockwise direction.  If rewind crank
(3) fails to turn, rewind all but a few inches of the film into the safety
cartridge; open backlid; and rethread film on to the take-up spool in the
manner described above.
  8. When camera contains film, the film Ioaded indication (13) will turn
red.

9. Finally, turn light value scale dial (27) so that the ASA rating of the
film in the camera is indicated on the filmspeed scale (26).
         CAMERA GRIP FOR PICTURE.TAKING
 Any comfortable and relaxed manner of holding the camera will do, so
long as the camera can be kept perfectly steady, and the fingers do not ob-
struct the viewfinder and rangefinder windows.
                              Grip camera from the sides with both hands,
                       so that index and middle fingers of the left
                         hand catch on the focusing lever (4), while
                         the right thumb is hooked lightly on the co-
                          cking lever (1), and the right index finger
                                rests lightly on the shutter button (2).
                                            t.  For horizontal pictures, bring camera up
                              to eyelevel without changing grip.  Close left
                                  €ye , and sight with right eye through the
                              eyepiece (10). Keep elbows close to body for                          www.butkus.us

maximum steadiness, and hold breath momentarily
when operating shutter button (see Cut A).
  2. For vertical pictures, there are two basic grips.
  Method one : Turn camera over to the left, with
left arm held close to the body for steadiness, and
with teft palm in firm contact with cheek. When
focusing in this position, use thumb and index finger
of left hand (Cut B).
  Method two:  Turn camera over to the right,
using right thumb and fingers to operate shutter
button and grip the right side of the camera. Keep
right elbow close to the body (Cut C).
            FOCUSING
  Sight subject through eyepiece (10) of the view-
finder. Note bright focusing spot in center of field.
Ad just  focusing lever (4) so that overlapping

)

images seen in the focusing spot merge into a single image. Accurate
focusing is essential at close ranges. For ease of judging merging of images,
make use of clearcut vertical lines, such as poles, window frames, and the
nose and cheek lines in portriat work.
. When the focusing spot images merge, the subject is in correct focus,
and the distance from the camera to the subject is indicated on the distance
scacle (21).
 By means of the depth of field scale (22) which lies adjacent to the
distance scale (21), it is possible to find the focusing tolerance for any given
aperture size.
 The bright translucent frame in the viewfinder field indicates the limits
of the subject as registered on the film. Because the brightly illuminated
optical frame is coupled to the focusing mechanism, parallax is automatically
compensated. There is no fear of lopping off heads.
 When taking vertical pictures,  it is often easier to focus first in the hori-
zontal position, then, shift to the vertical for picture composition and shoot-
ing.                         www.butkus.us

DEPTH OF FIETD
  Depth of field, or focusing tolerance, is the range along the optical axis
of the camera lens within which sharp register of the subject can be ob-
tained. This range depends on distance and aperture size (f/setting).
  1. The smaller the lens opening, the greater the depth of field or focus-
ing rolerance.                    k*         *    U5- U >  2. The farther away the subject, the greater the tolerance.
  3. The shorter the focal length of the lens, the greater the depth of
field.
  4. There is more focusing tolerance beyond the subject in focus than in
front.
  Depth of field depends very much on lens design, and on the degree of
sharpness of register (technically, the size of the circle of confusion) re-
quired.
 The focusing tolerance (depth of field) of the MAMIYA-SEKOR F 1.9,
f:48mm lens of the MAMIYA METRA Model 2 is given in the subjoined
table.

With proper awareness of depth of field, it  is possible to obtain photo-
graphs with sharp register of subjects at varying distances from the camera.
  For example, to obtain a picture of a human subject 10 feet (approxi-
mately 3 meters) from the camera in front of a building 40 feet (approxi-
mately 12 meters) distant, both in sharp register, the aperture setting should
be at  fl8, and the focus (distance setting) should be at 1b feet.  If,
at the same aperture setting, the camera is accurately focused on the subject
at 10 feet, background objects up to only 17 f.eet distant will  register
sharply.
  Using this principle, it is possible to dispense with focusing for subjects
more than 13 feet (about 4 meters) distant from the camera by pre-setting
the focus at 30 feet on the distance scale (21) and using aperture settings
of. f.l8 or less (8, 11 and 16).
INFRA.RED PHOTOGRAPHY
 When using infra-red film in conjunction with red color filter, correction
in focusing must be made to allow for the difference in refraction character-
istics. First adjust focus, then shift distance indicated on distance scale

needle, read the light value
on the meter scale (27).
Transfer this tight value
to the light value scale (16)
on the lens-shutter barrel
by adjusting the aperture
ring (I7). Correct exposure
will now be obtained pro-
vided the available range of
shutterspeed-aperture com-
binations is not exceeded
(see section on  shutter
operation).
 When  illumination  is
inadequate, and movement
of the meter needle cannot be discerned, use booster (amplifier) cell mounted
on accessory clip (24).  In  this case, re-set  light value meter scale (n),

using " AMP " index mark.
  When measuring light value of subject, get close to main subject, and                                        l
obtain average intensity of the reflected light. When, in taking snapshots                           I
or .scenery, it is difficult to approach the subject, point camera at subject
and foreground to avoid over-excitation of the photocell by skylight and                                                             i
background (See cut, preceding page).
  When photographing wide vistas or distant mountains, set light value scale         i
setting on shutter at one numeral above the indicated reading (see cut).
  When measuring light value of subject at close range, avoid creating sha-
dows on the subject.
  Under reyerse illumination conditions, with light coming from behind         isubject, if silhouette effect is desired, measure background light value; if
clear reproduction of subject detail is necessary, approach subject and
measure dark portion of subject.
 whe under reverse lighting, details of both the subject and background
are desired, use mean of the values obtained from the subject and the back-
ground.
                          www.butkus.us

When using a  filter,
compensate for absorption
 of the filter either by
 lowering the light value
 setting on scale (16), or
 shifting the filmspeed set-
 ting (26) to a lower value.
For instance, with a filter
of an exposure factor of
 X2, either the lens barrel
 light value setting is re-
duced one step, or the filmspeed scale setting is shifted from say 100 to 50.
               UNTOADING FIIII
  When the number of exposures (20 or 36) available on the film have been
'used up, do not attempt to take more pictures. Push sprocket release button
 (23), erect rewind crank (3), and turn in direction of arrow mark (clockwise)

to return exposed film into safety cartridge or special cassette. When end
of film, attached to the take-up spool, is freed, the easing of tension can be
sensed by feel, while the rewind indication (L2) will cease to turn.  Stop
rewinding as soon as the film loaded indication (13) turns blank.  Open
backlid, and remove safety cartridge or special cassette.
  Sprocket release button (23) will automatically return to original position
                   when cocking lever (1) is next operated.
                       CAUTION
                         1. When end of film is reached, the cocking
                          lever (1) may jam before completion of its stroke.
                         In this case, never apply force. Cocking lever can
                  be freed simply by pressing the sprocket release
                          button (23). Finish stroke, and allow cocking lever
                          to return to original position
                         2.  If jammed cocking lever is forced, film may
                          tear or break loose from cartridge Spool to prevent
                        rewinding except by opening camera in a photo.                          www.butkus.us

graphic darkroom.
  :J. If after unloading the camera is not reloaded, set light value meter
scale dial (27) so that filmspeed scale (26) indicates " EMP " (empty).
               SHUTTER OPERATION
  The SEIKOSHA-MXL shutter of the MAMIYA METRA Model2 is cocked
at the time of film advance by operation of the cocking lever (1), so double
exposure is positively prevented. All shutter controls (shutterspeed, and
synchroflash MFX adjustment) are operable with the shutter cocked (how-
ever, see 3 below).
  1. To set light value indicated by the built-in exposure meter on light
value scale (16) by means 6f the index mark on the aperture ring (17),
adjust both the aperture ring (17) and the shutterspeed control (14) on
which is engraved the light value scale (16).
  When, under extremely bright illumination,  it is necessary to set the LV
index mark (17) at 16 or 17 on the light value scale (16), it is easier to do
so without the camera cocked.

2. Once the correct light value is set on the light value scale (16), the
shutterspeed control (I4) will automatically regulate the aperture size; so
when depth of fietd is necessary, use slow shutterspeed. When taking
action photographs of subjects in motion, use high shutterspeeds, with extra
care in focusing.
 When changing shutterspeed, appty finger pressure to aperture ring (I7)
so that it moves in unison with shutterspeed control (L4) (see cut). Otherwise,
range of correct shutterspeed-aperture  combinations may be exceeded, with the
index mark (I7) slipping past the selected setting on the light value scale (16).
  3. When shifting from tlruo to tlron second with the camera cocked, consi-
derable resistance is encountered because extra tension is applied to the
                               shutter mechanism. It is preferable to make
                                 this change with the shutter uncocked.
                             4. With the SEIKOSHA-MXL shutter, the
                               interval between 250 and 500 on the shutter-
                            speed scale (14) is double the normal step.
                             Consequently, when shifting from 250 to 500                          www.butkus.us

or vice versa, the light value scale (16) must be shifted one step to maintain
correct correlation between shutterspeed and aperture size. When shifting
from 250 to 500, move up light value setting one step; when shifting from
500 to 250 or less, reduce light value setting one step.
 When shifting from 1 (automatic shutter action) to B (manual control),
exposure time must be doubled if no change is made in the aperture/LV  set-
ting. For each step of reduction in aperture size, the exposure time must
be doubled-4 seconds, 8 seconds, 16 seconds, and so on.
  5. Because of its internal construction, the SEIKOSHA-MXL shutter does
not provide intermediate shutterspeeds at intermediate settings. Consequent-
ly, the shutterspeed settings must be at the click stops, and the shutterspeed
control must be adjusted before selection of aperture settings. On the other
hand, the changes in aperture size are continuous; so it often happens that,
when using LV control, the aperture index mark (17) falls at some inter-
mediate position on the aperture scale (15).
  6. The threaded socket at the center of the shutter button (2) is provided
for attaching a cable release or a selftimer.



                ''.,r.':.1;; *

7. The shutter may be left cocked without harm to the mechanism except
when the camera is put away in storage for some time.
  8. The SEIKOSHA-MXL shutter provides full and accurate flash syn-
 chronization at all shutterspeeds with all types of flash (see below), and is
provided with M-F-X adjustment (20) and synchroflash terminal (19). In
normal use, when not using synchroflash, the M-F-X adjustment should be
 kept at position X (no delayed action of the shutter).
  9. When making blanl< shots, use shutterspeeds faster than Zs
(l/25 second) in order to save wear and tear on the automatic timing
mechanism.
            SYNCI{ROFLASH PHOTOGRAPHY
  For accurate flash synchronization at all shutterspeeds, the SEIKOSHA-
MXL shutter of the MAMIYA METRA Model 2 incorporates a delay mecha-
Yrism to allow for the time-lag that occurs before flashbulbs attain peak
intensity. Always set synchroflash M-F-X adjustment (20) at correct posi-
tion for the class of flashbulb used.
