A
    Insertingthe batteries

 The exposure meter of your REVUEflexSD'1 operates on two 1.5 V
  silver oxide batteriesavailablefrom FOTO-QUELLE.lf the batteries
 failand you have no spare batteriesat hand, your camera is not in
 a position to measure the exposure but it is prepared to take shots.

 Two batteriesare deliveredwith the camera. Avoid touchingthe
 battery poles (upper or lower side). Fingerprintslead to corrosion
 and later to contact problems.Therefore ensure that the batteries
 are only touched on their edges. Clean the poles before insertion by
 rubbing with a dry cloth.

 To insert, first unscrew the battery compartement cover @ with a
 coin. Then insert the batteriesso that the poles marked with " *  "
  (bright,flat part) are inward. (Observethe diagram inside the
 battery compartment.)Correct polarity is essentialfor proper
 operationof the camera's exposure system.
 Close the battery compartment cover @ and switch on the exposure
 meter @. This should cause one of the three diodes @ on the left
 of the viewfindereyepieceto illuminate. lf none of the diodes lights
 up, re-checkthe battery polarity. lf the signal fails even after battery
 check,the batteriesare depleted and must be replaced by new ones.

 Replacementof batteriesis necessarywheneverswitchingon the
 exposure meter does not cause one of the three light emitting
 diodes @ on the viewfindereyepiece to illuminate.The shutter
 speed knob @ may be in any position except for "B". When set to
 "8", the camera's exposure meter is ineffective.

 After battery check, switch off the exposure meter in order to save
 the batteries.
 As with every battery powered unit, it is also advisable to carry
 spare batteries for your REVUEflex SD 1 so that you are prepared for
 any eventuality.Rememberthat the strength of a battery is reduced                       www.butkus.us 22

at low temperatures.Therefore protect your camera from the cold
 as long as possible when making winter exposuresin order to
 improve the operation of the batteries-
 Removingthe batteriesfrom the camera and storing them separately
  is only advisable if you do not expect to use your camera for an extended period of time.                                         il

   Loading the film


 Your REVUEflex SD 1 is intendedfor 35 mm film (24 x 36 mm picture
 size). For economical prints from the REVUE lab, we recommend
 using REVUEcolor negativefilm.
 Avoid changingfilm in direct sunlight.Shade the camera with your
 body, if necessary,when loadingfilm. To load film, proceed as follows:  1. Open the back cover @ by pullingout the rewind knob @    f
    completely.
  2. Insert the film cassette into the film cassette compartment@ =
    protrudingspool shaft downward - and lock by pushingthe rewind
   knob @ down (if necessary,turn the rewind knob slightly)so that
    the rewind shaft@ engages in the film spool.
 3. Thread the film end - without touching the shutter blades@! - over
    the film gate and into one of the slots on the take-up spool@. With
    the film advance lever@, transport the film until the sprocket teeth
  @ properly engage the perforations.lf necessary,operate the
    shutter release@ and cock the film advance lever @ again.
 4. Unfold the rewind crank @ and tighten the film turning the crank
    clockwise (in the arrowed direction),
 5. Press the back cover closed and advance the film operating the
    shutter release@ and the film advance lever @ alternately until the
   exposurecounterO shows "1".When folded out, the rewind crank@
    serves as a transport control: lt must turn counter-clockwisewith
    every motion of the lever. After film transport, fold the crank in.
                                                           23

The camera is now ready to take the first shot.
 A film memory holder on the back.of the camera will accept a flap of
 the REVUEfilm carton so that you will have a reminder of the film in
 use.

G
   Setting the film speed


 Setting the speed of the film in use is of basic importance,as only then
 can the camera's exposure system provide proper exposure.
 You'll find your film's sensitivityindicated on the film packet,in DIN or
 ASA. On top of the shutter speed knob @, there is a small cut-out with
 the film speed scale which is also graduated in DIN and ASA.To set
 the film speed, move the film advance lever @ until it locks in ready
 position and projects out from the camera back cover. Now lift the
 knurled ring on the shutter speed knob with your thumb and your
 index finger and turn the ring until the correct DIN/ASAnumber
 appearsin the indicatorwindow. Two additionallock-inpositions
 between the whole numbers allow settings as accurate as 1 DIN
 (% stop value). Make sure, however, that the ring really snaps in place.
 When using always the same type of film, the film speed setting need
 only be made once. However,ensure to change the settingwhen
 loading a film with a different film speed. Only then you may rely on
 proper exposure.

D
   Cocking the shutter

 For easy carrying,your camera allows to fold the film advance lever @
 over the camera back cover. When taking exposures,you can swing it
 out to a ready positionso that your thumb may comfortablyslip
 behind it. A full motion of the lever will cock the shutter and advance
 the film one frame.The film advance lever is under spring pressure
 and will return to its basic position automatically.After cocking, the
 lever is blocked until the next exposure is taken.
 With every full motion of the lever,the exposure counter@ advances
 one number.Upon opening the camera back cover for removalof the
 film, the exposure counter automatically resets to "S" (start).
                                                                                  tfi
E
   Focusing


 The advantage of a single lens reflex camera ist that you do not have
 to set estimated distances on the range scale but can optically focus
 with accuracy in the viewfinder. For this purpose you can use the
 entire ground glass screen of the viewfinder.Besides,the REVUEflex
 SD t has two additionalfocusing aids in the middle of the viewfinder
 which permit fast and accuratefocusing:
 1. A split image rangefinderthat gives two half imageswhich are
    offset to one another as long as the range is not set correctly.
   Focusingis correct when an offset in the image can no longer be
   seen.The split image rangefinderis very useful for subjectswith
    clear vertical lines in horizontal format.
 2. A micro prism ring around the split image rangefinder.Here, a great
   number of microscopicallyfine prismsgive an emphasized
   focusingscreen effect - the subject is literallyruptured when not in
   focus.The flimmeringof the prisms makes the out-of-focuseven
                                                          25

more obvious. lf, however, the correct focus has been obtained, the
    micro prism screen gives a completely still,sharp image of the
    subject.The micro prism screen is not dependent on a particular
    subject structure and is therefore also suitable for subjects having
    no clearly recognizablelines.

F
    Film plane mark and infra-red index


  Focusing is also possible by measuring the distance by sight and
  settingthe focusing ring @ accordingly.The distancesgiven on the
  focusing ring refer to the film plane which is marked on the upper side
  of the camera behind the shutter speed knob @. The film plane mark
  can also be used as a reference when measuring the distance directly.
  For exposuresin black and white with infra-redfilm, you willfind a
  small index mark in red on the depth-of-fieldscale@, just above the
 f-number4, at the left of the central guide mark. This is the reference
  point for the settings to be made when using infra-red film. lnfra-red
  rays focus at a plane somewhat behind the plane at which visiblelight
  focuses. Therefore, a focus correction is necessarv.

G
   Depth of field


 The depth of field designates the nearest and furthest parts of the
  subjectwhich appear sharp in the picture at a given focusingsetting.
 The depth of field is influenced by three factors. lt decreaseswith:
          larger aperture opening
          shorter range
         longer focal lengthwww.butkus.us(telephoto lens).

The following table gives a survey of the interaction of shutter speed
  and aperture.

                                            great depth of field

 To give you the possibility of determining the depth of field with the
  working aperture set, your REVUEflexSD t has a depth-of-field scale                           f @on the lens,which has f-numbers engraved on both sides of the
  cintral index mark. As shown in the picture, the depth of field extends
  from about 3.5 m to 10 m when the camera lens is focused for 5 m
  a t f 8 .

    Setting the shutter speed

  The shutter speed knob @ provides you with 11fixed shutter speeds
  from 1 s to 1/'lOOOs. With the exception of "1", the numbers on the
  knob designatefractionsof a second.125,for example,means 1/125s'
  The setting "60" is marked in red and designates the slowest shutter
  speed for exposures taken with an electronic flash. The shutter speed
  knob must always be held by the catch in a fixed position. Inter-
  mediate positions are not possible. For "B" setting, see section "M".
