Fujica AX3 - The Evergreen State College
Operating Guide for Fujica 35mm Camera The Fujica AX-3 is a 35mm single lens reflex (SLR) camera (fig. A) with a variety of features. The camera can take aperture preferred automatic exposures. This means that you can set a desired aperture and the camera will automatically set the proper shutter speed for the correct exposure. The Fujica AX-3 is a sturdy camera designed to be used in the field or studio. Standard precautions must be observed when using the camera. DO NOT expose the camera to dust, dirt, extreme heat or cold, or mechanical shocks. Always wear the neck strap. When finished, replace the lens cap and soft shell case. NEVER CLEAN THE LENS WITH ANYTHING BUT LENS TISSUE AND LENS CLEANER! Keep the camera warm in adverse weather, as batteries lose their muscle when cooled. A final caution refers to the camera's very high susceptibility to moisture. Salt air mist will corrode the camera in a short period, resulting in expensive repair bills. Keep the camera in a camera bag especially when at the sea shore. Remember that you are fully responsible for loss or damage when you sign out equipment from Media Loan. SETTING THE ASA (FILM SPEED): This number refers to the film's sensitivity to light. The higher the ASA/ISO number, the less light is required for a proper exposure. All types of film have an ASA number. You must set the camera to this value for the exposure system to properly function with your film type. On the top left side of the camera is the rewind crank (9). Just below is the film speed selector (7) with a white lock (8) located to the left of the red ASA numbers. While depressing the white lock button on the side of the rewind crank, turn the ring underneath until the desired ASA number (that of your film) corresponds to the film speed setting mark (11). The marks labelled +1 and -1 on each side of the white set mark are used for exposure compensation. Be sure to use the center mark when setting the ASA. SETTING THE SHUTTER SPEED: Fig. A Single-Lens Reflex In the SLR camera, light from the subject strikes a mirror (a) and is reflected up through a pentaprism (b), which turns the image two ways and conveys it to the photographer's eye. When the shutter is activated, the mirror flips up (c) so that the film can be exposed. The shutter speed is adjusted by turning the ring that surrounds the shutter release (17) and reading the setting through the shutter speed window (23). The normal shutter and speed range of the camera is between 1/1000 and 2 seconds. The AX-3 also has two different automatic settings and a 'bulb' setting which keeps the shutter open as long as the shutter release is depressed. The first automatic setting is engaged by setting the shutter speed selector to "AE" (marked in orange). To exit this mode, the silver shutter speed selector lock (16) must be depressed while turning the shutter speed selector (fig. B). The "AE" setting puts the camera in "Aperture Preferred" automatic mode. This means that the camera automatically adjusts the shutter speed to match the aperture you select.

C). This setting is useful in situations such as brightly backlit subjects, where the averaging of the automatic exposure in the camera would normally overexpose the subject. LOADING THE FILM: Always load the film in shade or subdued light. Remove the protective case. Turn the camera on by pulling the main power lever (10) away from the body until the camera mode window reads "ON." Open the camera by pulling up on the rewind crank (9) until the back pops open. Insert the film into the left chamber, with the flat end of the film cassette on top. Push the rewind crank down to its original position, rotating slightly if necessary. Gently pull enough film from the cassette to insert it in the take-up spool. Advance the film with the film advance lever (21) until the sprocketed wheel has engaged both rows of sprocket holes (fig. D). Making sure the film is properly aligned between the guides, close the back and snap it shut. Advance the film (and release the shutter) until the exposure counter (18) reads "0." The film is advancing properly if the rewind crank turns counterclockwise while the film advance lever is being wound. FOCUSING The Fujica Viewfinder supports three focusing methods: 1. Split image: Look through the viewfinder and adjust the lens until the upper and lower part of the split image circle are continuous. This method is good for generally linear subjects. 2. Microprism Collar: This is the second visible circle in the viewfinder. The region between this circle and the split image circle is the Microprism. To use it turn the focus ring until the image in this region is sharp and clear. This method is best for non-linear subjects. 3. Ground Glass Screen: The widest circle in the viewfinder marks off the region of the ground glass screen. Focusing with this screen is not as accurate as the other two methods but it is much faster. Simply turn the focus ring on the lens until the image looks sharp in this region. NOTE: Focus can also be set using the distance markings on the lens in situations where normal through-the-lens focusing is not possible. Fig. B SHUTTER SPEED SELECT Fig. C SHUTTER SPEED SELECT LOCK Fig. D SETTING THE EXPOSURE: Looking through the viewfinder, press the shutter release halfway down. This activates the light meter and the red LEDs on the left side of the viewfinder. Rotate the aperture ring until the flashing light meets the stable light (fig. E). The exposure can also be adjusted by changing the shutter speed (fig. F). NOTE: If an LED indicator blinks steadily a few times per second by the "B" at the bottom of the viewfinder, the battery is low. Come to Media Loan for a new battery, or purchase a size N, 6 volt replacement at a local camera shop. TAKING THE PICTURE You are now ready for your first picture. Advance the film once, finetune your picture's composition, steady the camera, and squeeze the shutter release... REWINDING THE FILM The last frame of film is exposed when the counter is on 20, 24, or 36 and the advance lever will not move. To rewind the film back into its cassette, depress the white rewind button (20) on top of the camera (you may need to pull the film advance lever out a little first, and flip the rewind crank out and turn it slowly clockwise in the direction of the arrow). When you feel the tension release, turn the crank several additional turns. Pull up on the rewind crank until the back pops open and remove the film cassette. Push the rewind crank back down, close and press the shutter release to make sure the camera is not left cocked. Be sure to turn the main switch to "OFF." Fig. F analogy of the water faucet and shutter CARE FOR THE CAMERA 1. Dust off the camera periodically with a lint free cloth. 2. Use a good blower-brush to remove film fragments and dust from inside the camera, brushing gently and carefully around the shutter -- it is made of very thin material. Never touch the shutter, use only the blower brush. 3. Use a blow brush and/or Kodak lens tissue to remove dust and fingerprints from the front surface of the lens. Excess pressure can damage the lens coating. 4. Never touch or clean the reflex mirror inside the camera. 5. Always use the lens cap and keep the camera in its case when not in use. 6. Avoid storing or leaving the camera or film in excessively hot, cold, or humid environments. 7. When in doubt about use and handling of the camera, ask or call a Media Loan staff person. FEATURES AND ACCESSORIES SELF TIMER Self-portraits can be accomplished with the AX-3 by setting the main switch one stop further to the "SELF" position. The camera will the produce beeping tones for 12 seconds after the shutter release is depressed so you can get in position before the shutter actually opens. FLASH Media Loan has two models of Vivitar Flash units which can be used with the AX3. The flash is mounted on top of the camera using the hot shoe (12). See the Media Loan Vivitar guide for details. "A popular way to explain the functions of the shutter and aperture is to compare them to the controls of a faucet through which water lows into a container. In this analogy, water is light; the valve on the faucet, which determines the amount of water permitted to flow, is the aperture; and the length of time the valve is held open to permit a flow of water is the shutter speed. A certain amount of water flows into the container when the wideopen valve is held open for 5 seconds., and twice as much flows when the wideopen valve is held open for 10 seconds. Similarly, the shutter of the camera controls the length of time during which light is permitted to enter the camera. If the timing of the shutter opening is doubled, the amount of light the film is exposed to is also doubled." analogy of the water faucet and aperture AUTOMATIC EXPOSURE At times when you anticipate taking pictures quickly and under normal lighting conditions, it may be appropriate to use the automatic exposure or "AE" setting on the shutter speed dial. This camera follows an "aperture priority" logic, which means that you can now adjust the aperture for preferred depth of field and the camera will automatically select the appropriate Fig. E shutter speed. CAUTION: Pay attention to the shutter speed in the viewfinder; if it is too slow you may need to open up the aperture more. NOTE: To set the shutter speed manually when the camera is set on "AE" you must depress the "AE" lock button while turning the shutter speed dial. FLASHING LED "As with the shutter, the analogy of the faucet valve is useful in understanding how the aperture works. The length of time the faucet valve is open is the shutter speed; the degree to which the faucet is open is the aperture size. A wide-open faucet valve permits twice as much water to flow into the container in 5 seconds as one that is only half open. Similarly, if the size of the aperture opening is doubled, the amount of light the film is exposed to also doubles." LENSES The AX-3 employs a unique bayonet mount lens. We supply various lenses as well as adapters from "C" mount to bayonet. To change lenses, depress the lens release button on the left side of the lens (fig. G), turn the lens a quarter turn counterclockwise and cap the now-exposed end. Line up the red dot on the new lens with the red dot on the body of the camera, insert lens and rotate a quarter turn clockwise. You should hear a click when the lens is properly engaged.
