Lenses - The Model 600 Camera has a 127mm f/4.7 lens (Figures 1-5through 1.7). Two additional interchangeable lenses are available forModel 600SE (Table 1-2).

The interchangeable lenses use a bayonet type mount for attaching tothe camera body. A lens release button locks the lens to the camerabody.

The lenses are fully coated and color corrected. Each is in a shutter thatallows exposure control with a wide range of shutter speed/aperturecombinations.

All lenses are equipped with Seiko between-the-lens shutters. Each lenscomes with front and rear lens caps and a collapsible rubber lens hood.

Note: The 75mm lens comes with an accessory viewfinder.

Shutter - Seiko "S" shutters are contained within the lenses, providing shutterspeeds from 1 /500 sec to 1/sec, plus bulb and "X" synchronization.

The setting of shutter speeds is possible with the shutter in the uncockedor cocked position.

The shutter has a "B" (bulb) setting for time exposures. This allows theshutter to be held open as long as the exposure release is held down.

"X" synchronization allows the flash contacts to close when the shutter isfully open, at all shutter speed settings.

Filters - Model 600 and 600SE lenses accommodate standard screw-in filters(Table 1-2) for correct screw-in filter size.

Viewfinder - Both models 600 and 600SE cameras are equipped with acoincidence-type rangefinder in which two images come together withina circle when in focus.

The focusing range is from 3.5 feet (1.1 meter) to infinity.

The model 600SE camera has a single window, superimposed coupledrangefinder with a bright frame that moves for parallax correction.Framing lines within the finder can be selected for the 127mm and150mm lens fields-of-view.

A 75mm parallax corrected viewfinder supplied with the 75mm lens can bemounted on top of the rangefinder area of the model 600SE camera body(Figure 1-7).

The model 600 camera rangefinder/viewfinder has framing lines for the127mm lens only.

The framing lines, framing dots and coincidence image circle appear as bright yellow light in yourfield of vision.

For close up photographs of 10 feet or less, the picture is composed within the framing linesshown. When focusing beyond 10 feet, the picture is composed within the limits of the eightframing dots.

The Models 600 and 600SE are equipped with a coincidence-type rangefinder in which twoimages come together within a circle when in focus. Familiarize yourself with it by setting the lensat infinity. Now focus on a nearby subject.

View your subject through the bright yellow circle in the viewfinder. Position your eye so the entirecircle is visible. Within the circle your subject will appear as tow images. Turn the focusing ring sothat these two images coincide. Now the camera is focused on your subject.

Operation of the Viewfinder

The construction of the viewfinder built into the model 600 and 600SE camera is shown inFigure 2-4. The model 600 has framing lines for the 127mm lens only. The model 600SE has twosets of framing lines and lens indicators for the 127mm and 150mm lenses.

Figure 2-4. Operation of the RF/VF for the 127mm and 150mm lenses

The framing lines are contained on a piece of film. Light passes through the frosted glass windowand through the film containing the framing images.

The desired bright yellow color of the framing image results from the color of the beam splitter.

On the model 600SE, a metal mask (with a pattern of holes) blocks the light from one of theframing images. Moving the viewfinder selector switch moves this metal mask to reveal oneframing image on the film, and blocks the other framing image.

As the camera is focused from infinity to close up, the rangefinder coupling pin moves the framing-mask assembly. This causes the framing line image to move down, as shown in Figure 2-2. Thiscompensates for the change of viewing angle, between the camera lens and the viewfinder lens.

At the same time the rangefinder coupling pin pivots the movable mirror. This moves the movableimage from left to right. When the movable image coincides with the fixed image in the focusingcircle, the camera is in focus.

Viewing and Focusing with the 75MM Lens and Accessory Viewfinder

An accessory wide angle viewfinder is supplied with the 75mm wide angle lens. Figure 2-5shows the accessory viewfinder ready to be attached to the cold accessory shoe on top of thecamera.

Note: It is possible to attach an accessory viewfinder incorrectly. Avoid attaching the viewfinderpartially unlocked or backwards. Do not attach the accessory viewfinder to the hand gripflash shoe.

Unlock the viewfinder by turning the locking screw opposite to the direction of the arrow on theviewfinder. When fully unlocked, the locking screw can be seen in its topmost position. If thislocking screw is partially down, it will prevent the viewfinder from being fully seated on theaccessory show. Slide the chrome mounting base of the viewfinder into the accessory shoe.Push forward until the stopper screw on the accessory shoe is inside the square recess on themounting base.

Note: The viewfinder may feel snug and secure before it is fully seated. This is because it is heldby the guide springs on the accessory shoe. Do not leave it in this partially lockedcondition. The picture framing would be faulty and the viewfinder could be knocked off thecamera.

The locking screw should be on top of the stopper screw as shown in Figure 2-6. Turn the lockingscrew as far as it will go in the direction of the lock arrow. The viewfinder is now secured to thetop of the camera.

Camera Checkout

This section of the manual deals with the detailed inspection of the cameras. It will guide arepairman through a complete camera checkout. This is a required procedure for every camerareceived for repair. For the location of parts, refer to the Figures in Sections 1 and 4.

1. Examine the Neckstrap

Look for signs of excessive wear or faulty fastening rivets, tension slides, or keepers. Checkthat the D-rings are properly closed, holding the strap securely. Also be sure that the straplugs are properly secured in the camera body.

2. Examine the Exterior of the Camera Body and the Film Holder

a. If there are dents or cracks in the body or film holder, be sure that they don't interfere withoperation of the camera. Perform light leak test.

b. Inspect the tripod socket for stripped threads.

c. Examine action of film holder locks on both sides of camera.

d. Inspect bayonet lens mount for damage or defective springs.

e. Examine the viewfinder selector switch on the Model 600SE camera. Move the switch tothe 127 and 150 positions. Number in framing image should agree with selected number.

3. Examine the Film Holder Bail Latch

Unlatch the rear door from the film holder. Check the action of the release latch to be sure itdoesn't bind. Check the hinge area for excessive gap between the door and hinge. Close therear door and be sure both sides latch properly.

4. Examine the Film Holder Door Assembly

Release the rollers and pull them up out of the way. Look for broken plastic at the ends of thedoor. BE SURE THE ENTIRE EXIT DOOR AREA IS CLEAN.

5. Examine the A-11 Mini-Roller Assembly

With the rollers still in the unlatched position, examine them very closely for nicks, scratches, orencrusted foreign matter. Clean the rollers thoroughly. (NEVER USE ANYTHING WHICHCAN SCRATCH THE ROLLERS.) Be certain none of the parts is bent out of shape.

Note: Use only water to clean the rollers.

28

6. Examine the Rangefinder/Viewfinder (RF/VF)

Inspect the lenses to be sure they are not cracked, scratched or dirty. Move lens focus ringwhile looking through eyepiece. Inspect for smooth tracking of lens setting by the rangefinder.Perform parallax framing and tracking discrepancy tests.

7. Examine the Lens

Be sure the lens is not scratched. Clean the lens thoroughly. Move the focus ring; feel smoothaction. Perform lens collimation tests.

Note: Do not force or twist the lens barrel. It is very easy to damage thehelicoid assembly.

8. Examine the Shutter Action

Cock the shutter. Press the shutter release button. The shutter should trip when the shutterrelease button is pressed. Shutter speeds must be read on a speed tester.

Light Leak Test

1. Prepare the camera to take a picture. Mount film holder with dark slide onto the camera body.Load a 3000 speed (Type 107) film pack into film holder. Do not cock or release shutter.

2. Illuminate camera all around for one minute, with light from a 150 Watt lamp no closer thanthree (3) feet from the camera. Do not shine light directly into the exit door.

3. Remove unexposed film in normal manner, as if you had just taken a picture. Inspect film forlight leaks. Check that results are not due to old or defective film pack.

4. Remove dark slide. Again, illuminate camera with light for one minute. This time, concentrateon area around slot for dark slide. Remove second unexposed film frame.

5. Both frames should be totally black. If any spots, lines, or fogging are observed on the film,attempt to isolate leak area, by substitution of film holder or lens and/or covering suspectedarea with opaque black tape.

76

6. Compare the accented and masked light leak photographs to confirm location of light leak.Replace faulty light seal, as described in Section 4.

7. After replacement of light seal, repeat test. Compare film frames. Repeat until all light leakshave been isolated and eliminated.

Shutter speed Test

1. Remove the film holder and place the camera on a commercially available mechanical shutterspeed teste that can read shutter speeds in seconds and fractions of seconds. (Limitedclearance on some testers may require removal of the lens barrel from the camera, orremoval of the shutter from the lens barrel.)

2. Open the shutter to the widest aperture setting, f/4.7 stop or the f/5.6 stop. Trip and test theshutter through all the speed settings from 1 second to 1/500 second.

Note: Table 5-2 shows the allowable range of shutter speeds that are accepted by PolaroidCorporation.

RF/VF Parallax and Lens Collimation Tests

The purpose of parallax and collimation tests is to assure that near and infinity images seenthrough the camera can be focused onto film loaded into the camera. Therefore, you mustmeasure how closely "the rangefinder image coincidence" tracks " the lens sharpest focus", asdescribed in the following procedures; Infinity-Tube Tracking Test, and Near-Distance TrackingTest.

The interchangeable lenses of the Model 600SE camera have different rangefinder trackingdiscrepancy allowances. All three lenses (75mm, 127mm, and 150mm) should be tested beforedecisions about adjustments are made.

Collimation and parallax tests are subject to error due to the observer's eyesight and sightingability. A second observer should confirm results before major adjustments are made.

Topside Test

1. Plug in the power cord of collimator No. 11431 to a 110 vac electric outlet. Turn the line switchto ON. Turn the function switch to INF (infinity) .

2. Mount a camera on a tripod. Position it in front of the collimator as shown in Figure 5-1.

Figure 5-1. Camera setup for infinity-tube test

Infinity Tube

Tripod

Collimator

78

3. Look through the viewfinder eyepiece. Aim the camera at the collimator infinity tube. Turn thelens focus ring to infinity. The image you should see is shown in Figure 5-2. The image isinverted and slanted. If the image shown in Figure 5-2 cannot be seen clearly through theviewfinder, move the camera. Adjust aiming until a clear images obtained. It may benecessary to raise the tripod or move it left or right.

Figure 5-2. Perfect image of infinity target seen through the viewfinder at infinity

4. Move the lens focusing ring away from the infinity stop. Two images should be seen throughthe viewfinder eyepiece ( Figure 5-3). Turn the lens focus ring to get perfect imagecoincidence. (This may not be the infinity stop position.)

Figure 5-3. Split image seen through viewfinder

Topside discrepancylimit is width of base line.

5. If the base lines do not line up, remove rangefinder top cover and make any necessary topsideadjustment (Figure 5-4). If necessary, use trichloroethylene to free topside adjusting screw.Turn topside adjusting screw only. Observe movement of infinity-tube-target image through theviewfinder eyepiece. Adjust until base lines line up as shown in Figure 5-2. The base linesmust butt each other to be within allowable limits. Replace top cover.

Infinity Tube Tracking Test

1. Completing the topside the test Steps 1 through 5 prepares the RF/VF for this test.

2. Sight through the RF/VF eyepiece. Focus to get perfect image coincidence. Mark with apencil the location of perfect image coincidence on the distance scale of each lens as shownin Figure 5-5.

3. Focus the loupe on focal plane plate No. CCR-12262. The focal plane plate has a flat glasssurface. When this plate is loaded into the film holder on the camera, this glass surface isaccurately located at the focal plane of the camera. The loupe on the plate allows you to see amagnification of an image focused through the camera lens onto this focal plane surface.Use a scribe mark on the glass surface to focus the loupe to your eye. Each observer will haveto focus the loupe individually. Seek the maximum contrast between the dark area of thescribe mark and the brightness of the background. When the sharpest image of the scribemark on the focal plane is obtained, lock the loupe eyepiece with the locknut.

4. Set the camera for collimation test, as follows:

a. Remove the lens cap.

Note: Be sure the camera lens is clean before the camera is collimated.

b. Remove dark slide from film holder. Open door on film holder.

c. Place the focal plane plate No. CCR-12262 into the film holder as if it were a film pack(Figure 5-1). Check that the plate is fully seated to the right.

d. Set the aperture to the smallest number (largest opening).

Aperture127mm lens = f/4.7150mm lens = f/5.675mm lens = f/5.6

e. Set the shutter to "B" (bulb).

f. Cock the shutter.

g. Trip and tape the shutter release depressed into the hand grip to keep the shutter open.

5. Measure Collimation Tracking Error at Infinity, for each lens.

a. Sight through the focal plane loupe at infinity tube target. Aiming of the camera from thisparallax test should be adequate. Make focusing correction, if required, so that 40mmgrid is seen clearly, as shown in Figure 5-6.

b. Obtain the sharpest focus of infinity tube target image through each lens. Mark this locationon the distance scale of each lens, as shown in Figure 5-7.

81

Figure 5-6. Infinity-tube as seen through focal plane loupe

Figure 5-7. Measuring collimation tracking error at infinity

c. Measure tracking error by using a ruler or other measuring device to measure gap;Xbetween marks on the distance scale of each lens. Tracking error = " X ", cannotexceed the following limits:

Lens Xmax Xmax

82

d. Correcting Tracking: If error exceeds these limits, an adjustment is required. However,perform aiming and framing target tests before making adjustment. Also verify any grossdiscrepancies before adjusting. Leave pencil marks on the distance scale, so infinitytracking error can be compared to near distance tracking error.

Before making an adjustment to the Model 600SE camera, you must compare thecollimation tracking error measured sighting through each interchangeable lens. Thiscomparison will avoid needless adjusting back and forth of the three lenses and viewfinder.In most instances, a single adjustment of the infinity range screw will be sufficient to bringthe tracking discrepancies of all three lenses within allowable limits.

Aiming and Framing Target Test

1. Mount the reporter aiming and framing target No. ECR-12261, on a wall, as shown inFigure 5-8.

Figure 5-8. Reporter aiming and framing target

2. Mount a vertical strip of black tape 3/4 inch (2cm) wide by 6 inches (16cm) long to the target,above the center square.

Find the center of the framing target. (Use long straight edge or stretch string across thediagonals of the inside of the framing rectangle, to find center.) Use a tack to mount theaiming circle ACR-12438 at the center of the target.

3. Move tripod a couple of inches from the target. Adjust and lock height of tripod so that thecenter of the lens is at same height as the center of the aiming circle Figure 5-9).

Black Tape

83

Figure 5-9. Camera lined up with aiming circle

4. Remove tape from shutter release. Remove focal plane plate from film holder. Load a 107 or108 film pack. Remove film pack dark slide.

5. Move the tripod back from the target, as follows:

Lens Suggested Distance

127mm 80.5 inches (2 meters)150mm 96 inches (2.5 meters)75mm 44 inches (1.2 meters)

Note: The same suggested distances apply to the near-distance tracking error testprocedure. On the Model 600SE camera, complete tests on a single lens at thesuggested tripod position., Then move tripod to next position and complete testsfor the additional lenses.

6. Look through the viewfinder eyepiece. Try to position the camera so that the albada lineslineup with the target framing lines as shown in Figure 5-10.

View each corner separately. Make sure the albada lines are between the target lines andare spaced evenly left to right.

a. Test 127mm lens first. Move viewfinder selector switch to the 127 position.

b. When testing the 150mm lens make sure the 150 position is set by the viewfinder selectorswitch.

84

8. If the intersection is outside the aiming circle, adjust the position of the viewfinder.

Note: Do not correct aiming errors by adjusting the position of the lens assembly.

a. Adjust the 127mm and 150mm aiming errors to the left and right by shifting the left-to-rightposition of the rangefinder/viewfinder. Figure 5-13 shows the location of the three brassscrews which secure the viewfinder to the body of the camera. Remove top cover.Loosen the screws, only enough to shift the RF/VF position.

b. Up-and-down 127mm and 150mm aiming errors can be adjusted by placing a small shimunder the viewfinder assembly.

e. Take an aiming photograph as previously described. Scribe lines and determine if errorhas been corrected, as shown in Figure 5-12.

Near Distance Tracking Test

1. Mount the camera on a tripod at the same distance as used in the aiming and framing tests(Figure 5-17).

Lens Suggested Distance

127mm 80.5 inches (2 meters)150mm 96 inches (2.5 meters)75mm 44 inches (1.2 meters)

2. Look through the RF/VF eyepiece. Adjust the lens barrel focusing ring to obtain perfectcoincidence of the vertical tape at the center of The Reporter aiming and framing targetNo. ECR-12261. Mark with a pencil the distance scale of each lens as shown in Figure 5-18.

Note: Do not move tripod or camera, until collimation test is completed.

3. Set the camera as follows, for collimation test. The camera and tripod position should not bechanged from the image coincidence position.

a. Remove the lens cap.

Note: Be sure the camera lens is clean before the camera is collimated.

b. Remove dark slide from the film holder. Open door on film holder.

c. Place the focal plane plate No. CRR-12262 into the film holder as if it were a film pack(Figure 5-17). Check that plate is seated to the right. Obtain sharp focus of the scratch onthe focal plane.

d. Set the aperture to the smallest number (largest opening).

Aperture127mm lens = f/4.7150mm lens = f/5.675mm lens = f/5.6

e. Set the shutter to "B" (bulb).

f. Cock the shutter.

g. Trip and tape the shutter release into the hand grip to keep the shutter open.

4. Measure collimation tracking error at near distance for each lens.

a. Sight through the focal plane loupe and aim camera at the tape on The Reporter aimingand framing target.

b. Obtain sharpest focus of each lens of the tape target image through the focal plane loupe.Mark with a pencil this location on the distance scale of each lens, as shown inFigure 5-19.

c. Measure tracking error by using a ruler or other measuring device to measure gap: X,between marks on the distance scale.

Tracking error = X, cannot exceed the following limits:

Lens X Max X Max

127mm 0.039 inches (1/32 1 mm150mm 0.078 inches (5/64) 2 mm75mm 0.090 inches (3/32 2.3mm

5. Make tracking discrepancy adjustments.

a. If tracking discrepancy exceeds the set limits, an adjustment is required. Verify any grossdiscrepancies. Verification should be done by a second observer.

b. On the Model 600SE, comparison of the results of the tracking error measurements foreach of the three lenses should be made, in order to determine which adjustment to make.

c. Make the following parallax adjustments listed in Table 5-3 to correct tracking errors. Thenretest to assure elimination of tracking error from each of the three lenses.

Table 5-3. Parallax Adjustments

Adjustment Comment

RF/VF Infinity This is the preferred adjustment; it is easily accessible andRange (Screw) provides the widest range of adjustments (Figure 5-20).

RF/VF Near Distance Use for near distance fine adjustment only. Use only if error(Eccentric Screw) is not resolvable by infinity range adjustment and near

distance tracking error is larger than infinity error.

This is normally a factory setting (Figure 5-21)

Lens Barrel Coupling Use for gross error in one of the interchangeable lensesPin (Screw) of Model 600SE camera ( Figure 5-22). Adjust until

tracking error is within allowable discrepancy limits.

6. Lens collimation adjustment. If the adjustments described in Step 5 will not bring the trackingdiscrepancy to within the limits listed in Step 4, adjust the position of the front lens.

a. Use a lens spanner wrench to loosen the front lens lock ring (Figure 5-23). Put a fewdrops of trichloroethylene around the outside of the front lens lock ring. Let it soak into thethreads a few minutes. Break the shellac bond and free the front element.

b. Set the lens into a camera mounted on a tripod in front of the collimator, as shown inFigure 5-1. Turn the lens bezel to the infinity stop position.

Set the collimator switch to infinity.

Cock the shutter. Trip and tape the shutter release to keep the lens open.

c. While looking through the lens adapter loupe, slowly turn the lens until the 40 lines/mm isclear. Stop turning when you see the 40 lines/mm sharpest.

d. Move the camera to the aiming and framing target as shown in Figure 5-10.Look through the viewfinder eyepiece. Adjust focus until the images of the tape linecoincide. Mark the distance scale.

e. Look through the focal plane loupe. Slowly adjust the lens until the sharpest image is seen.Mark the distance scale.

f. Measure the tracking discrepancy at near distance by using a ruler or other measuringdevice to measure gap between marks (d. and e. above) on distance scale. Thediscrepancy cannot exceed limits listed in Step 4. Adjust lens to reduce error.

g. Return to the infinity tube and move the focus back to infinity. The minimum reading mustbe 40 lines/mm.

h. When the image seen through the lens loupe is sharp at both infinity and near distanceposition, lock the front lens lock ring.

Secure the front lens to the mount by applying three drops of shellac at equidistant pointsaround the lens. DO NOT DRIP SHELLAC ONTO THE LENS.

7. Perform any necessary rangefinder/viewfinder adjustments, after this lens collimation has beencompleted.
