Your First Rule





                                                 Before you load or unload a film, before you remove or fit the magazine, before you press the release--always
                                                cheek that the crank is unfolded and blocked.

www.orphancameras.com

                                                For this purpose swing the crank fully forward as far as it will go (1) and back again to its stop (2).

                                                  This tensions the shutter. It also sets up the automatic safety interlocks to prevent film waste during film changing
                                                      or magazine changing. Accidental double exposures, blank frames and overlapping pictures are impossible.4www.butkus.org

                                          Once the crank locks, you know immediately c that the camera is ready for correct operation.





Shooting Practice

You will find everything on the next four pages: from loading the fresh film to unloading the exposed film.

You can also practice the individual steps a a camera without film. For this the came' must be in its standard shooting state - with the magazine attached and the slide pulled
out (push it into the storage compartment I the back).

Loading the Magazine
View original page 6
Page 7 · Read text
The procedure for loading the magazine is the same whether it is on the camera or off the camera. When only one
                                            magazine is in use, there is no need to remove it from the camera. In this case the magazine slide remains permanently
                                                      in the storage compartment in the rear of the magazine.

                                               Basic rule: Unfold the crank (1) and turn it forward and backward until it  locks.4www.butkus.org

                                      To open the magazine: Unlock the back (2) and swing open (3). This also makes the magazine knob (4) jump out; the
                                               exposure counter (5) now indicates No. 1. Grip the film insert by the central bar (6) and swing it out of the magazine.

                                                    Setting the film counter to 12 or 24 exposures: Switch over the setting lever (7). The film counter (5) shows by its
                                         number - 12 or 24 - whether the magazine is set for No. 120 or 220 roll film.

                                     You can switch over even when the magazine is closed, as long as the film counter still shows No. 1.

                                            Loading a roll film: Swing open the spool holder (8). Remove the seal of the roll film (9) and fit the spool between the
                                                   fixed and the hinged shaft pins so that the black inside surface of the backing paper (10) faces outwards. Run the
                                               backing paper round the film insert and thread it into the slot (11) of the empty spool. With one or two turns of the
                                                 gear wheel (12) tighten the paper leader firmly well. This will keep the distances between the exposures sufficiently
                                                 small to avoid a possible loss of the 12th or 24th exposure (film transport control may be interfered by film windings
                                               being too loose).





Checking for Readiness to Shoot
View original page 7

 Grip the film insert by its centre bar and slide it into the magazine with the take-up spool first, so that the gear wheels
 on the insert and inside the magazine engage (13). Check the film advance by a short turn of the magazine knob (14).
 Then swing the magazine back closed (15) and check that it locks.

 Advancing the film to exposure No. 1: Turn the magazine knob until it locks and then push in (16). The backing
 paper is now spooled up and the film feeler mechanism has locked any further film transport: the film is ready for the
 first exposure. For subsequent exposures the crank advances the  film.4www.butkus.org

 Releasing the magazine knob. On depressing the release (17) with a pointed object the magazine knob springs out.
 Thus the film can be wound off and unloaded after any shot-- even with the magazine removed from the camera.

 The loading indicator (18) in the underside of the magazine shows a dot and a dash in line like an exclamation mark:
 "The magazine is loaded!'. When the magazine is empty, the dash is at right angles to the dot.

 The Rolleiflex SL 66 is now ready to  shoot.4www.butkus.org





If in doubt, it is possible to check with the crank lock even after loading the film whether the camera is correctly set: push the lever (19) in the direction of the crank handle
and at the same time try to turn the crank. If the crank is not locked, swing it down, let 9 of the lever (19) and complete the crank movement forward and back again. The
camera is now ready to shoot.
If you notice that you forgot to wind the crank only when pressure on the release has no effect, the same procedure still avoids wasting a film frame.
You can lose the first picture - and in fact wind the film through completely - only if the cranking movement was not complete an the crank is not pointing forward. While
this in no way harms the camera, you can avoid it by making a habit of checking the locking of the crank before loading the camera.

Shooting

Page 9 · Read text
Turn the lens cap to the left and remove. Open the focusing hood (1). To close, push in the side panels.

                                      To raise the magnifier press the key (2). To fold it back again, press down the magnifier frame between magnifier and
                                                    the front of the focusing hood (3) until it engages.
                                                        1. The Shutter Speed

                                           Turn the knob (4) to engage the appropriate shutter speed. The figures 1000 to 1 are fractions of a second, B is the
                                                       setting for time exposures of any duration. Intermediate speeds cannot be set.

                                                   Shutter speeds for flash: see page  13.4www.butkus.org

                                             Exposure value correction: see pages21 and 25.
                                                        2. The Aperture

                                           Turn the aperture ring (5). It engages at full and half stop settings.

                                         The 40 mm, 50 mm, 80 mm, 120 mm, 150mm and 250 mm lenses have a fully automatic spring loaded iris
                                              diaphragm. The lens remains fully open until the moment of exposure. The aperture closes down to the pre-selected
                                                 value only on pressing the release.

                                             For other lenses: see page 20
                                                        3. Focusing

                                           Turn the focusing knob (6) until the picture appears sharpest on the screen (7).

                                          With lenses of very long focal length and when using extreme depth tilt the mirror may cut off a strip near the top of
                                                    the screen image. The film in every case still records the full picture area.

                                                Distance scale: see page 10. Depth of field: see page 11.

                                           Depth tilt: see page 12.
4. Releasing

Unlock the release button (by turning) and press (8). When the red dot is visible from above, the release is locked. When the red dot is not visible from above, the release is
free.

Time exposures at the B setting: Press down the release button for the duration of the required exposure time or keep it in the depressed position by the locking collar. The
shutter only closes on unlocking or letting go of the release.

The release button incorporates a cable release thread.

Film Transport and Shutter Tensioning





 After every exposure unfold the crank and turn it fully forward and back again until it locks (9). The forward swing
 tensions the shutter while the return swing to its final position advances the film. The camera is then ready for the next
 exposure. During shooting the crank may remain unfolded for immediate operation.

Unloading the Magazine

 After the last exposure the magazine knot springs out when you turn the crank - an audible and visible sign that the film
 is finished.First complete any started crank movement (10) swing fully forward and back. Then keep turning the
       orgmagazine knob (11) until the remainder of the backing paper is spooler up and the knob turns freely without resistance.4www.butkus.

 Open the magazine (12) remove the insert Swing away the spool pin and take out the exposed roll.
 Transfer the now empty feed spool to the take-up end from which the exposed spool was removed. This now becomes
 the take-up spool for the next film.





Film transport principles summed up: To advance the film from exposure to exposure always use the crank-- but wind up backing paper leaders and trailers always with
the magazine knob.

Distance Scale

 At every subject distance the Rolleiclear focusing screen with central micro prism provides a direct and precise
 check on the image sharpness.

 The distance scale on the focusing knob is normally used only for depth of field estimation, for zone focus settings
 and when using flash.

 The figures on the distance scale apply only to the first complete turn of the focusing knob (with the lens mounted
 the right way round). The distances are measured from the film plane to the subject.

 To adapt the scale to the interchangeable 50, 80, 150 and 250 mm lenses the focusing knob contains stored in it
 four distance scales. The focal length corresponding to the scale in use is shown on the face of the knob. For
 changing the scale see page  16.4www.butkus.org

 The bellows extension of 2 inches (50 mm) can be further increased by extension tubes of 40 and 80 mm used
 either singly or in combination. This yields still nearer focusing distances with all lenses.

 With the lens mounted in "retro" position subject distance can be further reduced for (reversed, front element
 facing the film) the I still larger scales of reproduction.

 Focusing ranges: see page 25.




Scale of Reproduction

www.orphancameras.com





                                                   In close-up work the scale of reproduction is more important than the subject distance. With the aid of the scales (for
                                                     three focal lengths) on the bellows rail you can set the camera directly to the required scale of reproduction. In this
                                                 case the best way of getting the subject sharp is to bring the camera nearer to or farther away from it.

                                                Explanation of the scale (1):

                                         The four scales apply to the focal lengths of 80, 150 and 120 mm (normal mounting) and 80 mm fitted back-to-front
                                                       ("retro" mounting). The triangular marks indicate the orientation of the aperture setting index on the lens when the
                                                             latter is mounted normally (2) and back-to-front  (3).4www.butkus.org

                                         The magnification factor to the left of the horizontal setting mark indicates the scale of reproduction on the film
                                             (image size/subject size), e. 9. 0.4 = 0.4 :1. The required exposure correction is indicated above the bar (for instance -
                                     = reduce the exposure value by 1 step).

                                         The figures are set and read off along the common scale limit (the degree scale).

                                         The centre line indicates the length of the bellows extension in millimeters. For the scales of reproduction with
                                                       different bellows extensions for all focal lengths, including the use of extension tubes, see page 21.

                                         The contra line also acts as the index for the degree scale when tilting the lens (depth tilt: see page 12).





Depth of Field
You can check the extent of the depth of field directly on the focusing screen or indirectly on the focusing knob.

1. For lenses with spring loaded iris diaphragm press the stopping-down key (4). This can be locked by inclining it and released the same way. The lens then stops down
the pre-selected value. The ground glass screen is particularly suitable for this check on the final image appearance.

2. Opposite the distance scale index lines with appropriate aperture figures show the extent of the depth of field (for a circle confusion of 56 microns or 0.0022 inch). Either
estimate the actual subject distances measure by accurate focusing of the screen Image.
Beyond the first full turn of the focusing knob or when using the depth tilt the figures act index values for the measured distances.
View original page 12
Page 13 · Read text
At increased extensions the effective aperture of the lens changes. When the bellows tension is more than half the focal length, the effective aperture (which is what matters
for the exposure and the depth of field) no lone corresponds to the f-number engraved on the lens scale. For actual depths of field under these conditions see page 25.



Extended Depth





                                              You can gain extended depth by tilting the lens axis when the subject is confined to one plane at an angle
                                                                    to the camera. By tilting the camera and in addition tilting the lens axis it becomes possible to extend the
                                                        zone of sharp reproduction over a large distance range even at full aperture. You can increase this zone
                                                                    further by the depth of field gained on stopping down.

                                                                Tilting the lens: Release the locking knob (1) by turning to the left. Press down the lever (2) and raise or
                                                          lower the lens to set the centre line of the scale (3) to the required value on the degree scale. Then tighten

3. The angle of tilt of the lens.
In practice you can determine these three values in every case with the aid of the indicator (see page 26).

Pre-releasing the mirror

The movement of the instant return mirror is mechanically and pneumatically braked during releasing. The mirror starts to swing slowly, accelerates and then slows down
again. The gentle conclusion of the swing movement helps to keep the camera steadier.
In addition you can pre-release the mirror, for example when using a not very rigid tripod, for shots with long focal lengths or in the extreme close-up range.

To pre-release the mirror: Press down the sliding key (4). Release the shutter in the usual way. After the exposure the mirror returns into its viewing position.

To bring the mirror back again without taking a picture, cover the lens with the lens cap, release the shutter and retension it with the film transport disengaged (see Multiple
Exposures, page 13).

FP-Synchronization
Long peak FP (focal plane) flash bulbs are available specially for focal plane shutters. They yield a uniform light output over a longer period. These flash bulbs can be
synchronized with the fastest shutter speeds. Their maximum light output is utilised at about 1/60 second.

Exposures with Filters

The 50 mm, 80 mm, 120 mm, 150 mm, 250 mm, and 1000 mm (Tele-Tessar) lenses have the same size VI bayonet mount and use the same filters.

To tit the filter: Insert the filter in the inner bayonet ring of the lens and secure by turning fully to the right.

The 500 mm Tele-Tessar uses its own screw in filter.

The 1000 mm Tele-Tessar uses filters of bayonet size VI inside the lens body (see separate instruction manual).

The 1000 mm Mirotar requires special filters which are inserted from the side in the optical path of the lens.

The filter mounts carry, where applicable, a correction value for the exposure value (for example --1.5 for the medium yellow filter). This correction value is deducted from
the measured exposure  value.4www.butkus.org

Exposures with the Lens Hood

The same lens hood fits lenses of 80, 120 150 and 250mm.

A special hood is used for the 50 mm lens, a retractable hood is part of the 500 mm lens. An integrated hood belongs to the 1000 mm Tele-Tessar. The 30 mm and 40 mm
lenses as well as the 1000 mm Mirotar are used without any lens hood.

To tit the hood: Place the lens hood in any position over the outer bayonet ring and secure by turning to the right.

                                                  Separate magazines are supplied with a protective cover. This is always used on the free magazine. To fit the
                                             magazine to the protective cover or to detach it, proceed as with the camera (6).

                                    When the magazine is off the camera it is closed light-tight by the slide; you can load it in the same way as a
                                             magazine on the camera (releasing the magazine knob --> page 7 7).

                                                                 If you have pulled out the slide of a spare empty magazine and accidentally moved the outer cog wheel of the
                                                magazine, the slide will not go in fully. Remedy: half pull out the slide (7), turn the cog wheel in the direction of the
                                               arrow (8) until it locks, and push back the slide.

                                            Important note: To ensure reliable operation of the film feeler system, the film insert of the magazine must not be
                                                    interchanged. Always check that the serial number of the magazine (on the mating surface for the camera) is the
                                          same as that on the film insert (at the left hand side).

Interchangeable Lenses

+ Diaphragm Systems:

A--Fully automatic spring-loaded diaphragm. The iris is always fully open. When you release, it closes down to the pre-selected aperture just for the duration of the
exposure.

V -- Pre-selector aperture. The diaphragm closes down to the pre-selected value when you rotate the setting ring to its stop.

E -- Geometric aperture scale, shown in relative exposure factors. With the Luminar lenses the scale starts at 1 for the full aperture engraved on the lens; each succeeding
value corresponds to an exposure interval of one lens stop. The factors indicated facilitate the calculation of the exposure increase over the exposure at full aperture.

The Mirotar mirror optical system has no diaphragm and is always used at its full aperture of f/5.6. Here the exposure may be controlled by altering the shutter speeds or if
necessary by fitting special neutral density filters.

* With diaphragm shutter

* Luminar lenses: The data apply in every ease to the Luminar without adapter. The Luminar lenses 16, 25, 40, 63 mm use the same adapter with microscope thread.
