Lenses

The Model 600 Camera has a 127mm f/4.7 lens (Figures 1-5 through 1.7). Two additional interchangeable lenses are available for Model 600SE (Table 1-2). The interchangeable lenses use a bayonet type mount for attaching to the camera body. A lens release button locks the lens to the camera body. The lenses are fully coated and color corrected. Each is in a shutter that allows exposure control with a wide range of shutter speed/aperture combinations. All lenses are equipped with Seiko between-the-lens shutters. Each lens comes with front and rear lens caps and a collapsible rubber lens hood.

Shutter

Seiko "S" shutters are contained within the lenses, providing shutter speeds from 1 /500 sec to 1/sec, plus bulb and "X" synchronization. The setting of shutter speeds is possible with the shutter in the uncocked or cocked position. The shutter has a "B" (bulb) setting for time exposures. This allows the shutter to be held open as long as the exposure release is held down. "X" synchronization allows the flash contacts to close when the shutter is fully 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 a coincidence-type rangefinder in which two images come together within a 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 coupled rangefinder with a bright frame that moves for parallax correction. Framing lines within the finder can be selected for the 127mm and 150mm lens fields-of-view. A 75mm parallax corrected viewfinder supplied with the 75mm lens can be mounted 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 the 127mm lens only.

Figure 2.2. Framing a picture

Viewing and Focusing with the 127mm and 150mm Lenses The image shown in Figure 2-3 can be seen by looking through the eyepiece of either the model 600 or model 600SE cameras. In the model 600SE camera the viewfinder frame is adjustable for the 127mm and 150mm lenses. The number that appears just below the top right framing line indicates the lens that has been selected. Sliding the selector switch to the other position ;changes the framing image to match the focal length of the other lens. A lens indicator number does not appear in the model 600 image area. 19

The framing lines, framing dots and coincidence image circle appear as bright yellow light in your field of vision. For close up photographs of 10 feet or less, the picture is composed within the framing lines shown. When focusing beyond 10 feet, the picture is composed within the limits of the eight framing dots. The Models 600 and 600SE are equipped with a coincidence-type rangefinder in which two images come together within a circle when in focus. Familiarize yourself with it by setting the lens at infinity. Now focus on a nearby subject. View your subject through the bright yellow circle in the viewfinder. Position your eye so the entire circle is visible. Within the circle your subject will appear as tow images. Turn the focusing ring so that 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 in Figure 2-4. The model 600 has framing lines for the 127mm lens only. The model 600SE has two sets of framing lines and lens indicators for the 127mm and 150mm lenses.

The framing lines are contained on a piece of film. Light passes through the frosted glass window and 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 the framing images. Moving the viewfinder selector switch moves this metal mask to reveal one framing 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 framingmask assembly. This causes the framing line image to move down, as shown in Figure 2-2. This compensates 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 movable image from left to right. When the movable image coincides with the fixed image in the focusing circle, 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 2-5 shows the accessory viewfinder ready to be attached to the cold accessory shoe on top of the camera. Note: It is possible to attach an accessory viewfinder incorrectly. Avoid attaching the viewfinder partially unlocked or backwards. Do not attach the accessory viewfinder to the hand grip flash shoe.

Slide on the accessory viewfinder from rear of camera.

Avoid a partially locked locking screw interfering with full insertion of the mounting base into the shoe.

If this locking screw is partially down, it will prevent the viewfinder from being fully seated on the accessory 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 the mounting base. Note: The viewfinder may feel snug and secure before it is fully seated. This is because it is held by the guide springs on the accessory shoe. Do not leave it in this partially locked condition. The picture framing would be faulty and the viewfinder could be knocked off the camera. The locking screw should be on top of the stopper screw as shown in Figure 2-6. Turn the locking screw as far as it will go in the direction of the lock arrow. The viewfinder is now secured to the top of the camera.

" Right " Locking screw is locked on top of stopper screw. Mounting base is fully inserted into accessory shoe.

Camera Checkout This section of the manual deals with the detailed inspection of the cameras. It will guide a repairman through a complete camera checkout. This is a required procedure for every camera received 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. Check that the D-rings are properly closed, holding the strap securely. Also be sure that the strap lugs 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 with operation 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 to the 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 it doesn't bind. Check the hinge area for excessive gap between the door and hinge. Close the rear 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 the door. 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, or encrusted foreign matter. Clean the rollers thoroughly. (NEVER USE ANYTHING WHICH CAN SCRATCH THE ROLLERS.) Be certain none of the parts is bent out of shape. Note: Use only water to clean the rollers.

6. Examine the Rangefinder/Viewfinder (RF/VF) Inspect the lenses to be sure they are not cracked, scratched or dirty. Move lens focus ring while 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 smooth action. Perform lens collimation tests. Note: Do not force or twist the lens barrel. It is very easy to damage the helicoid assembly.

8. Examine the Shutter Action Cock the shutter. Press the shutter release button. The shutter should trip when the shutter release 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 than three (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 for light 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, concentrate on 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 suspected area with opaque black tape.

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 leaks have been isolated and eliminated.

Shutter speed Test 1. Remove the film holder and place the camera on a commercially available mechanical shutter speed teste that can read shutter speeds in seconds and fractions of seconds. (Limited clearance on some testers may require removal of the lens barrel from the camera, or removal 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 the shutter 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 Polaroid Corporation.

3. If any of the above speeds are not met within its allowable range, the shutter must be replaced. Shutter repair is not covered in this manual. Shutter removal is covered in Section 4 and in videotape training instructions.

RF/VF Parallax and Lens Collimation Tests The purpose of parallax and collimation tests is to assure that near and infinity images seen through the camera can be focused onto film loaded into the camera. Therefore, you must measure how closely "the rangefinder image coincidence" tracks " the lens sharpest focus", as described in the following procedures; Infinity-Tube Tracking Test, and Near-Distance Tracking Test. The interchangeable lenses of the Model 600SE camera have different rangefinder tracking discrepancy allowances. All three lenses (75mm, 127mm, and 150mm) should be tested before decisions about adjustments are made. Collimation and parallax tests are subject to error due to the observer's eyesight and sighting ability. 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 switch to 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.

Infinity Tube

Collimator

Tripod

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

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

Topside discrepancy limit is width of base line.

Base Line

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 through the viewfinder eyepiece ( Figure 5-3). Turn the lens focus ring to get perfect image coincidence. (This may not be the infinity stop position.)

Figure 5-3. Split image seen through viewfinder

5. If the base lines do not line up, remove rangefinder top cover and make any necessary topside adjustment (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 the viewfinder eyepiece. Adjust until base lines line up as shown in Figure 5-2. The base lines must butt each other to be within allowable limits. Replace top cover.

Spring

Figure 5-4. Location of topside adjusting screw

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 a pencil the location of perfect image coincidence on the distance scale of each lens as shown in Figure 5-5.

Image Coincidence

Figure 5-5. Marking image coincidence at infinity

3. Focus the loupe on focal plane plate No. CCR-12262. The focal plane plate has a flat glass surface. When this plate is loaded into the film holder on the camera, this glass surface is accurately located at the focal plane of the camera. The loupe on the plate allows you to see a magnification 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 have to focus the loupe individually. Seek the maximum contrast between the dark area of the scribe mark and the brightness of the background. When the sharpest image of the scribe mark 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). Aperture 127mm lens = f/4.7 150mm lens = f/5.6 75mm 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 this parallax test should be adequate. Make focusing correction, if required, so that 40mm grid is seen clearly, as shown in Figure 5-6. b. Obtain the sharpest focus of infinity tube target image through each lens. Mark this location on the distance scale of each lens, as shown in Figure 5-7.

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

Best Loupe Focus

Image Coincidence X

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 ", cannot exceed the following limits: Lens

Xmax

127mm 150mm 75mm

0.039 inches (1/32) 0.078 inches (5/64) 0.090 inches (3/32)

1mm 2mm 2.3mm

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 gross discrepancies before adjusting. Leave pencil marks on the distance scale, so infinity tracking error can be compared to near distance tracking error. Before making an adjustment to the Model 600SE camera, you must compare the collimation tracking error measured sighting through each interchangeable lens. This comparison 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 bring the 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 in Figure 5-8.

Black Tape

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 the diagonals of the inside of the framing rectangle, to find center.) Use a tack to mount the aiming 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 the center of the lens is at same height as the center of the aiming circle Figure 5-9).

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 or 108 film pack. Remove film pack dark slide. 5. Move the tripod back from the target, as follows:

Note:

Lens

Suggested Distance

127mm 150mm 75mm

80.5 inches (2 meters) 96 inches (2.5 meters) 44 inches (1.2 meters)

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

6. Look through the viewfinder eyepiece. Try to position the camera so that the albada lines lineup 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 and are 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 selector switch.

7. Set the aperture and shutter speed to suit film speed and available light. Cock and release shutter, to take a picture of the target. Scribe cross lines from the outside corners of the picture as shown in Figure 5-12. The intersection of the scribe lines must be within the aiming circle. The intersection of the scribe lines must be within the aiming circle.

Figure 5-12. Aiming measurement

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-right position of the rangefinder/viewfinder. Figure 5-13 shows the location of the three brass screws 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 shim under the viewfinder assembly.

d. Up-and-down 75mm aiming can be adjusted two ways (Figure 5-15). First check that the distance scale on the accessory viewfinder agrees with the measured distance to the target. If in error, adjust distance scale to agree with measured distance. Use spanner wrench with pencil point tips to loosen lock-screw.

80.5 inches (2 meters) 96 inches (2.5 meters) 44 inches (1.2 meters)

2. Look through the RF/VF eyepiece. Adjust the lens barrel focusing ring to obtain perfect coincidence of the vertical tape at the center of The Reporter aiming and framing target No. 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 be changed 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 on the focal plane. d. Set the aperture to the smallest number (largest opening). Aperture 127mm lens = f/4.7 150mm lens = f/5.6 75mm 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 aiming and 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 in Figure 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

127mm 150mm 75mm

0.039 inches (1/32 0.078 inches (5/64) 0.090 inches (3/32

1 mm 2 mm 2.3mm

5. Make tracking discrepancy adjustments. a. If tracking discrepancy exceeds the set limits, an adjustment is required. Verify any gross discrepancies. Verification should be done by a second observer. b. On the Model 600SE, comparison of the results of the tracking error measurements for each 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. Then retest to assure elimination of tracking error from each of the three lenses.

Table 5-3. Parallax Adjustments Adjustment

Comment

RF/VF Infinity Range (Screw)

This is the preferred adjustment; it is easily accessible and provides the widest range of adjustments (Figure 5-20).

RF/VF Near Distance (Eccentric Screw)

Use for near distance fine adjustment only. Use only if error 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 Pin (Screw)

Use for gross error in one of the interchangeable lenses 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 tracking discrepancy 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 few drops of trichloroethylene around the outside of the front lens lock ring. Let it soak into the threads 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 in Figure 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 is clear. 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 line coincide. 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 measuring device to measure gap between marks (d. and e. above) on distance scale. The discrepancy 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 must be 40 lines/mm. h. When the image seen through the lens loupe is sharp at both infinity and near distance position, lock the front lens lock ring. Secure the front lens to the mount by applying three drops of shellac at equidistant points around the lens. DO NOT DRIP SHELLAC ONTO THE LENS. 7. Perform any necessary rangefinder/viewfinder adjustments, after this lens collimation has been completed.
