TOPCON BEttOW ATTACHi,IENT, Model tV
The TOPCON Bellow Aitochment, Model lV, is o very superior equipment for use in mocro-
 phofogrophy ond hos mony feotures, which hove been incorporoted to help you in using the
equipment with optimum performonce ond eose. One of  ifs moin feotures, or will be
exploined fully, is fhe double rocking system, with the upper rocking system being used
for continuously extending the dislonce between lens ond film for determining the scqle of
reproduction os required, while the lower rocking system is utilized for moving the complete
set-up, for odiusting the distonce to the subiect.
Furthermore, the two rocking systems moy be seporoted for independent use, thus doubling
the possibilities for their ufilizotion, with the lower rocking system then being convenient os
on independent focusing system for close-ups, copying work, photomicrogrophy,  etc.
Together with other occessories, prepored for use in combinotion with the Model lV, it con
be soid thqt the Model lV  is q true professionol fype equipment ond mokes up o very volu-
oble component in the TOPCON System of Photogrophy, centering oround the TOpCON RE
Super, with its Thru-The-Lens Mirror-Meter System.
This monuol hos been prepored to ocquoint you with some of the finer points of the Mode!
lV Universol Bellows, ond its specificotions,  construction,  etc., os well os to give you some of
the bosic focts of mocrophotogrophy, so thot your enioyment in using the equipmenf will be
doubled.

CONSTRUCTIONAT FEATURES
One of the chief feotures of the Model lV Bellows is the twin poirs of double roils, which moy
be seporoted ond used independently or in combinotion, for double rocking.
The top poir of corrioge rods, on which the bellows move, hos helicql rocks cut on one rod
 f or use in rocking the bellows in ond out, with scoles of reproduction figures  f rom 0.5 X to
3 X engroved on the rod for use with 5gmm lenses. The other ploin (without helicol rock)
rod hqs extension scoles engroved for use of the RE. Auto-Topcor lenses ond the Mocro-Topcor
58mm lens, with 5mm scole divisions. In oll instonces, the front end of the bellow fronf
corrioge is used for olignment with the scoles.
The front corrioge of the bellows is rocked farword or bockword with the lorge bellow move-
ment knob. No clomping knobs ore required since the front corrioge will not creep forword
even with the lens ottoched ond the bellows used ln q verticol position. The reor bellow
corrioge moy be freely moved by loosening the reor cqrrioge clomp, in which cose the
comero con be moved forword so thqt the bellows con be bunched ot the forword end of
the top corrioge rods, when necessory.
Two holes or sockets qre ovqilqble on the f;'ont end of the top poir of roils, for inserting
the ottoehment rods of the Mocro-Stond Attcchment or Slide-Copying Attochment. These ot-
tochments moy be fixed firmly by tightening the screw on the side of the front member.
The bottom poir of roils olso hqs helicol rqcks cut on one of the roils, for use in providing
rocking oction to the movoble tripod mount, for use in positioning the occessory (including
top roils with comerq ond lens, etc.). Rocking is undertoken with the lorge tripod mount
movement knob, ofter completely loosening the tripod mount clomping knob first. Once the

www.butkus.us
occessory hos been positioned, the clomping knob must be tightened securely. Adiustment of
the tripod mount position is very convenient when the bellows hove been set to o certoin
scote of reproduction ond connot be disturbed or when the occessory must be rocked for-
word becouse the tripod connot be moved forword.
The top ond bottom poirs of  roils moy be detoched quite simply, by loosening the fixing
screw on the lotter ond then pulling them oport. When ottoching the top ond bottom
roils, first insert the guide pin on the front end of the top roils into its socket on the
bottom roils, then ploce the guide pin on the reor end of the bottom roils into o socket
on the bose of the top roils ond, ftnolly, screw in the fixing screw knob.
The fixing screw of the bottom roils ond the tripod screw socket on the movoble tripod
mount ore mode to the some specificqtions os the tripod screw ond, therefore, con be used
with comeros, tripods, tripod heods, copying stonds, etc.
The front qnd reor corrioge stondqrds <rre very compoctly designed, becouse of the hexq-
gonol-shoped folding bellows which is most efiicient for  extensison or controction of  the
bellows. Both front ond reor stondords hove boyonet mounts, for ottochment of lens ond
comero respectively. Furthermore, the front lens stondord con occept extension tubes,
reverse-odopter  rings, outomotic extension tube, focusing extension tube, boyonet odopters
for the Mocro-Topcor 30mm lens, etc., without influencing the smooth extension/controction
of the bellows ond without requiring clomps for holding the bellows in ploce.
The reor boyonet mount, for occepting the comero body, con be revolved 90 degrees, for
toking verticol formots, but moy qlso be clomped ot ony intermediote ongle,  if preferred.
When the bottom roils ore used independently with the comero, the comero is ottoched on
the reor end of the rqils, focing outwords, so thot the reor end will now be the front end,

                              I

for  qll purposes. The guide pin on top of the reor end is inserted into o groove on the
front end of the comero's bose (of the TOPCON RE Super or  RE-2), which will properly
olign the iwo, ond then the fixing screw is tightened to secure the two, or comero ond
bottom roils.
When using the bottom roils on the copying stond, for providing yerticol odiustment, the
comero is ottoched, os nDted obove, ond then the movqble tripod mount is ottqched to the
copying stond. The TOPCON copying stond olso hos guidi pins which ore inserted into
olignment grooves on the movoble tripod mount, for properly ffxing the two.

USE OF THE BEILOWS
I. Ailochment of Comercr





   The comero is ottoched to the bellows, in the some monner os interchongeoble lenses
   ore ottoched. In other words, line up the red doi on the reor boyonet with o similior
   red dot on the body flonge, insert corefully qnd, when well-seoted, turn clockwise until
  o full stop is mode, where it will click into position.
  The lens con be removed by pressing the lens locking lever, on the comerq body, ond
   rototing counter-clockwise until the two red dots ore lined up. The two ore then sepo-

roted corefully.
2. Afiqchment of the Lens
   The lens, os well os extension tubes  whiclr moy be inserted in between, con be ottqched
   to the bellows' front boyonet in the some monner qs noted for the comero body.
   Alwoys be sure to rotqte fully until o clicking sor.rnd is heord, indicoting fhqt the lens    locking pin hos engoged.
   Set the distonce focusing ring to infinity on the distonce scqle.
3. Setling the Scole of Reproducfion
   The scoles engroved on the top roils moy be used for vorious purposes, depending on the
   interchongeoble lens or the combinotion of lens ond occessory being used on the bellows.
  The scqle engroved on the top roil, on the side of the bellow movement knob, shows

www.butkus.us
     the scoles of reproduction for the 58mm lens.
    The reor corrioge of the bellows must, however, be rqcked bock to the reor end of the
    top roils qnd fixed securely with the reor corrioge clomp. The front corrioge should then
    be rocked forword with the bellow movement knob ond the scole olignment surfoce, on
    the front end of the front corrioge, should then be oligned to the required scqle of
     reproduction figure.
    For exomple,  if the  f ront corrioge is oligned to  I X, then life-size close-ups will be pos-
     sible (with the 58mm lens). Since the intervol between eoch scole division is 29mm, ond
                                                              in ihis cose, will be 58mm.I   becouse the lens is set to infinity, the totol extension,
    The lenses  f or which the scoles of reproduction con be used ore  : -
         RE. Auto-Topcor 58mm f /1.4 stondord lens
         RE. Auto-Topcor 58mm  f /1.8 stondord lens
       Mocro Auto-Topcor 58mm f/3.5 lens
        Mocro-Topcor 58mm f/3.5 lens, with focusing extension tube
   Two scoles ore engroved on the roil opposite thot with the scoles of reproduction ond
    show the extension in 5mm divisions. As con be seen, the top ond bottom scoles ore
     difierent. Thot on top is for use with oll RE. ,Auto-Topcor lenses while thot on the
    bottom is for use with Mocro-Topcor lenses, when ottqched directly to the bellows (with-
    out focusing extension tube).
     In the cose of the RE. Auto-Topcor'lens, the scqle is used to indicote the lens exten-
     sion which is mode in oddition to the minimum extension of 29mm, due to the bunching of
    the bellows. However, in the cose of Mocro-Topcor lenses, this minimum extension is
    equol to the length of the focusing extension tube ond, therefore, omounts to photog-

rophy ot infinity or zero millimeter extension, thus vequiring o different extension scole.
As con be seen from the obove, the Mocro-Topcor lens is very convenient for  trovel- ing    or for field                   trips becouse                            the                           some lens                                      cqn                                            ihen                                                          used                                          be                                                                 for ordinory                                                                          outdoor                                                                                              shots (ot infinity          or close'ups,                        with the                                   bellows)                                   ond                                            then                                                      used,                                        be                                                             without                                                                       further                                                                                          occessories,
for toking extreme close-ups, thus eliminoting the need to cqrry o tot of equipment.
Lenses which cqn be used with the extension scoles ore:_

    Mocro-Topcor 30mm f/3.5 lens (Refer to the instruciion mqnuol for the lens)
when using these lenses for mocrophotogrophy, the omount of extension con be foundfor the required scole of reproduction from the following bosic formulo, which is qlsoexploined in FORMULAS FOR MACROPHOTOGRAPHY.

   For exomple, when the RE. Auto-Topcor l00mm f/2.8 lens is used, the extensions for the
   scoles of reproduction 0.5X, I X ond 1.5X, con be  colculoied from the formulo, with
   the following resulis: -         0.5 X .                         ..... 50mm extension

4. Allernole Mefhod of Setling the Scale of Reproduction
   As noted, the reor corrioge of the bellows must be rocked bock to the reor ehd of the
   top roils ond fixed securely with the reor cqrrioge clomp, in order to use the scoles of
 12

NodalI   Point         Frlm Plane o     reproduction or the extension scoles engroved on the
      *2emm--l            top roils. Thus, when it is necessory to move the reor  t--f                            corrioge forwcrd, both scqles connot be utilized ony
                                      longer, moking it rqther difficult to set the lens to the
                                   required position for toking shots ot specific scqles
                                  of reproduction.
                                     ln such cqses, it should be remembered thot the dis-
                                  lcnce from the reor nodql point of the lens to the
                                       film plone, when the reor ond front corrioges  ctre
                             --1                 bunched together (without bellow extension) will be  f-sz"-                     the focql length of the lens plus o 29 millimeter exten-
                                          sion, ond thot the distonce from the front end of the
   front corrioge to the reor end of the reqr corricge, in this cose, will be 52mm.
   Simply by utilizing the obove informotion, it will still be possible to use the scoles of
   reproduction for the 58mm stondord lens, or, in other words, olign the front surfoce of
   the front corrioge with the I X engroving qnd rock the reqr corrioge forword until the
  two cqrrioges <:re bunched together. Clomp the reor corrioge ot this point. Next, rock
   the front corrioge forword to the l.5X  engroving, which will meon thot the lens hos
  been extended 58mm becouse the distqnce between scoles of reproduction figures is 29mm.
   Or, the millimeter extension scoles moy olso be utilized in similior monner. Thus, the
   front corrioge cqn be coinclded io zero millimeter ond the reor corrioge brought for-
  wqrd until it is together with the front corrioge, which will qlreody meon on extension
  of 29mm. By rocking the front corrioge forword the required exfension distonce (minus
                                                                                                          t3

          the initiol 29mm), it  will be possible to ploce the lens ot the position required for ob-
             toining the required mognificotion.
           However, when the lens is used reversed, the storting point for the lens will differ from
            thot of the normol lens becouse of the difference in the flonge length ond the reor lens-
              to-film plone distonce for the vorious lenses. (See toble on poge 40) lt should not be
                difficult to moke the necessory odiustments, once the storting point is defermined from
           the toble.
        5. Polnlers for Mocrophologrophy
          The colibrotion of the extension scoles is usuolly sotisfoctory for use with the indicoted
            scoles of  reproduction but, for yery precise use, it is recommended thot o scole be
           photogrophed together with subiect or thqt the No. 4 Focusing Screen be used for
            toking ihe picture
           Generol purpose photogrophic lenses hove been designed primorily for toking shots of
             subiects qt ,for distonces, or  inffnity, ond, therefore, better results con be obtoined by
             using Mocro-Topcor lenses, which hove been designed for obtoining greoter resolution ot

As noted previously, the ottochment must be used ottoched to the front end of the bellows,
in which cose it provides o suitoble plotform for toking extreme close-ups of smqll flot ob-
iects, when the set-up is used verficolly. Simply insert the ottochment rods into the sockets
on the front end of the bellows, fix ot q suitoble posiiion qnd fhen tighten ihe smqll

        The mocro-stond hos been designed to provide o speedy method of ffxing the stond ot the

         of reproduction figures on the mocro-stond ottochment rods qnd thot on the bellows, for
         the 58mm lens. In other words, one of the qttochment rods hos scoles of reproduction from
                I X to 3 X ; thus, it  is only necessory to fix the mocro-stond ot the required scole of re-
