•In the event the flash unit does not fire when you press the Shutter Release Button (2), check to see that the flash cord is securely plugged into Flash Cord Outlet (7) , and that On/Off switch of flash unit is in "ON" position. Finally, make certain the Selector Dial (6) is at "X" position. D o not press down on Shutter Release Button ( 2) unless actually taking a flash picture. Pressing this button down fully will fire the flash whether or not the Film Transport Lever ( 1) has been wound. Should this happen, however, no loss of film will occur. A lways remember to set Shutter Speed Dial (5) to 1/30th second, and Flash Synch Selector Dial (6) to X position for electronic flash photography. At other speeds or settings, the flash will not synchronize fully with the shutter. USING FLASHCUBE OR FLASHBULB GUNS In general, flashcubes and bulbs are more costly than electronic flash, and less conven ient to use as the bulbs must be replaced after each picture (with flashbulbs) or each four pictures (with flashcubes). Should you wish to use these light sources, however, follow Steps 1-5 above, with this exception: F or flashcubes or flashbulbs, move the Flash Synch Selector Dial (6) to "M" position. This adjusts the timing mechan ism of your camera to insure that the shutter opens when the flash of the bulb is at its brightest. Leave the Shutter Speed Dial at 1/30th second for all flash pictures. D etermining exposure with flashcubes or bulbs is done the same way as with manual (non- automatic) electronic flash units, as described ab ove.

USING LONG EXPOSURE TIMES ( TIME EXPOSURES) Time Exposures are exposures of one second or longer. At these extra-long exposure times, you can photograph city streets at night, dimly-lit interiors, and many subjects too faintly illuminated for normal picture-taking. To take a time exposure with your Cosmorex, set the Shutter Speed Dial (5) to "B", press the Shutter Release Button (2) ... and simply hold it down until the desired number of seconds has elapsed. When you release the Shutter Button, the shutter will close. For extra steadiness, use of a locking Cable Release and a sturdy Tripod are recommended when taking time exposures. I n the event a locking cable release is not available, you can keep your cameras shutter open for extended periods quite simply. With the shutter at "B" position, press down the shutter release firmly. Hold it down, and ro tate the Release Button (2) counter-clock wise (towards the left) until it stops. Now, the shutter remains open as long as desired. To close the shutter when the exposure is com pleted, press down on the Release Button and turn Release clockwise until it stops. After a time exposure using this method, always make certain the Shutter Release Button (2) and Rewind Release Ring (3) are both turned fully towards the right: this will insure correct opera tion of shutter and exposure counter in subse quent pictures.
• Under certain conditions, your cameras exposure meter may be used when making Time Exposures. First, make sure that the existing light is sufficient for use of the meter (p. 12); then, "match the needle" and read the correct exposure time in full seconds from the Red numbers 30, 15, 8, 4, 2, 1, which appear furthest from the Black numbers 30- 500 on the exposure meter Shutter Speed Indicator Dial (21). T he Red numbers 15, 8, 4, 2, appearing next to the Black numbers 30-500, repre sent fractions of a second: "15" is 1 /15th second, and so on. These numbers appear for information purposes only, when using your cameras meter to determine expos ure with cameras lacking a built-in expo sure meter.
USING SELF-TIMER Your Cosmorex camera is equipped with a built- in self-timer.

Move Self-Timer Lever (10) counter-clock- wise until no further movement is possible. (As you move it, youll notice the "M" sticker underneath the Self-Timer Lever. This is simply a reminder to move the lens to "M" [Manual] position as described). 5. Press Self-Timer Release Button (9). Youll hear a "whirring" noise, which indicates that the timer is functioning. Now, walk away from the camera into the scene being photographed - the shutter will fire auto- matically in about ten seconds.
*Make sure you have moved the Self-Timer Lever as far as it will go before pressing the Release Button. If the Lever has not been fully wound, the shutter will not operate. (Should this happen, just move the Self-Timer Lever downwards again - fully this time - and press the Release Button again.) *If you decide not to use the Self-Timer after moving the lever down, simply take your next picture by pressing the Shutter Release Button (2). Then, before moving the Film Transport Lever, press the SelfTimer Release Button (9) and the Timer will return to normal position. Do not leave the Self-Timer Lever in "wound" position for extended periods. CHANGING LENSES Your Cosmorex SE single-lens reflex camera accepts literally hundreds of fine lenses in the popular "Universal" (42mm) thread mount. To remove your lens, just grasp firmly, and turn it to the left (counter-clockwise) about three turns. To attach a lens, simply screw it into the cameras lens mount by turning it clockwise until no further movement is possible. A fter changing lenses, check that the Auto/ Manual Switch (14) is on "A" position before picture taking. This insures that you will be able to frame and focus easily.

T hread-mount lenses, particularly lenses of different manufacture, may sometimes "seat" with the aperture and distance scales slightly to the right or left of "center" position. This does not indicate any defect in your camera or lenses, and in no way affects camera/lens operation. T ake care not to expose your cameras interior to dust, dirt, or moisture when the lens has been removed. Always replace the lens on the camera body as soon as possible. W hen removing or storing lenses, protect them from accidental damage by placing the lens face down and, if possible, attach ing a rear lens cover ( available from your dealer, and usually included with accessory lenses). Y our Cosmorex accepts interchangeable thread- mount lenses from 16mm wide angle to 1000mm ultra-telephoto. S tandard automatic lenses of this type incorporate a single metal pin (illustrated) through which your camera actuates the lens automatic diaphragm mechanism. NOTE: Thread-mount lenses specifically designed for SLR cameras of a particular model other than the Cosmorex may in- corporate special "keying" levers (illus trated). Such lenses should not be used on your camera . This manual created and owned by www. butkus.org/chinon, it should not be found elsewhere.
r At 1/30 a -s econd CHOOSING SHUTTER SPEEDS AND LENS OPENINGS For the majority of outdoor subjects, a shutter speed of 1/125th second is suggested. This speed is fast enough to prevent blur due to slight movement of the camera during ex posure, and also fast enough to "freeze" most normal movement of the subject - people walking, moving cars, etc. For situations when the subject is really moving fast - children at play, sports events, racing cars, for example - shoot at 1/250 or 1 /500th second if theres enough light to allow this. Conversely, shooting at 1/60th or 1/30th second is recommended only when there is no appreciable movement of the subject (a landscape, for example), or when the use of small lens openings (f/11 or f/16) is de sired to give the deepest zone of sharp focus. Shutter speeds may be selected before or after the Film Transport Lever (1) has been wound. However, always lift the Shutter Speed Dial (5) before turning it to another speed, and return it " down" before shooting. Finally - always turn the Shutter Speed Dial (5) to one of the marked speeds (B, 30, 60, 125, 250, or 500). Do not move to posi tions between marked speeds.
CHOOSING DIFFERENT LENS OPENINGS Your 58mm automatic standard lens has open ings ( apertures) from f/2 to f/16. At f/2, the greatest amount of light is transmitted to the film; at f/16, the amount of light transmitted is least. Each marked number represents a 50% change in light transmitted. The Aperture Ring (26) of your lens may be set at any marked lens opening (f/2, f/2.8, etc.) or at positions in between marked lens openings. If the Exposure Meter Aperture Indicator Dial (20) indicates a lens opening between two f/numbers (lens openings), turn the lens to the in-between position. USING DEPTH-OF-FIELD FOR GREATER SHARPNESS All photographic lenses, when focused on a given subject, will show some objects in front of, and in back of, that subject more or less sharply. This "zone" of extra sharp ness is called "depth-of-field", and varies with different lenses; its greatest with wide angle lenses, and least with telephoto lenses. With any lens, youll find your depth-of-field is always greater (more things in focus) at small lens apertures such as f/ 11 or f/16, and lesser (fewer things in focus) at larger lens apertures such as f/2.8 or f/2. In most picture taking, this phenomenon is of no particular importance, as the subject will, in most cases, appear equally sharp at all lens openings. However, the area of sharp focus or "depth-of- field" does become important in certain situations.
Example: youre taking a picture of a land- scape - and you want everything needle sharp from the foreground, all the way to the background. Your Cosmorex lets you achieve this easily and reliably, in several ways: A. Using Depth-of-Field Scale (27). Heres how: 1. Focus on the closest object which will appear in the picture. (Example: ten feet away as indicated by the white number on your Distance Scale [28] .) 2. Now, focus on the most distant ob ject which will appear in the picture. ( Example: "Infinity" as indicated by your distance scale [28] .) 3. Move the Focusing Ring (13) of your lens until the greatest distance (infinity) and the closest distance (ten feet) ap pear in front of the same lens aperture numbers on the Depth-of-Field Scale (27) of your lens. ( Example: f/11). Set aperture ring (26) to this opening. 4. Use your cameras built-in exposure meter to determine the correct shutter speed for an exposure at this lens open ing. (Example: shutter speed of 1/60th second for lens opening of f/11.) Set Shutter Speed Dial (5) to this speed.
5. Take the picture! Everything between the two distances (10 and infinity) shown by the matching f/11 numbers on the Depth-of-Field Scale (27) will appear sharply.

Youllbe abletosee howdistantandnearbyob jects"sharpen up"atsmallerlensaper turessuchasf/11 or f/16. Naturally, when the lens is "stopped down," less light enters the viewfinder, and it is more difficult to see or focus clearly. The principal benefit of this technique is that it gives you a fast, accurate "preview" of what will and will not be sharp in the finished photo- graph - for example, that telephone pole in back of your subject. If it appears sharply when the lens is "stopped down" to the intended aperture, it will appear sharply in the final photograph. By pre viewing your depth-of-field in this way, youll soon learn to select the aperture required for the depth-of-field you want . Either of these techniques will prove valu- able in the great majority of picture taking situations. For extremely critical applica- tions, a printed depth-of-field chart is availa ble on request.
