Film Advance and Shutter Release Around the shutter release button is a lock lever. When it is turned to "L" (LOCK), the shutter button is locked. This lever should always be in the "L" position to prevent battery consumption and film wastage by accidental shutter release when the camera is not in use, such as when it is in a camera case.
When the shutter release button lock lever is turned to "A", the shutter release button can be operated. This shutter release button turns on the camera's meter and releases the shutter to take a shot.
Being electromagnetic, it requires only very gentle pressure for blur-free pictures. When it is pressed lightly only halfway, the camera's meter turns on and gives a reading inside the viewfinder. When it is pressed all the way down, the shutter is released. Once the shutter has been released, the film advance lever can be advanced. To advance the lever, first lightly push it away from the camera body to its 30 degree stand-off position. In this position, it can easily be advanced with the tip of your thumb. Advance it either by pushing it all the way to the right in a single throw or with several short strokes until it stops. When film is loaded, this action will wind the film to the next frame. Once advanced, the lever will automatically return to its stand-off position in readiness for the next winding.
Note: This camera does not have a multiple exposure mechanism. To prevent an unintentional double exposure, the shutter release button is locked after the shutter is released until the film is wound to the next frame. Then the film advance lever locks until the shutter is once again released.
Film Loading Slides, color or black and white film in standard 35mm cartridges can be loaded. When loading and unloading film, avoid direct sunlight and take care NOT to touch the shutter curtain, the film rails or the pressure plate.
To load the film: 1. Unfold the rewind crank and pull sharply up on the rewind knob. The camera's back cover will pop open.
2. Place the cartridge in the film cartridge chamber so that the protruding end of the cartridge is on the bottom. 3. Push the rewind knob down and rotate it until it drops into position to keep the cartridge in place.
4. Now pull the film leader across the camera and insert its tip into any slot of the multi-slot take-up spool. 5. Advance the film once. Make sure the film perforations are engaged with the teeth of the film transport sprocket. 6. Gently turn the rewind crank in the direction of its arrow until it stops. This takes up film slack. 7. Close the back cover and fold the rewind crank.
Now take two blank shots, turning the film advance lever and releasing the shutter, so that the frame counter advances from "S" to "0". While doing this, keep an eye on the rewind knob. If it rotates, the film is properly loaded. If it does not rotate, unfold the rewind crank and turn it again gently in the direction of the arrow to take up possible slack. Advance the film once more. If the rewind knob still does not rotate, open the back cover and reload the film. Chances are that the film perforations have not engaged properly with the teeth of the take-up spool and the film transport sprocket.
Setting the Film Speed (ASA) Each film has a film speed. The film speed is usually stated in two ways: ASA, the American standard, and DIN, the German standard. These values can be found on the film packaging or on the data sheet which comes with the film. This camera uses the ASA value.
The ASA film speed must be set on the camera or your pictures will not be exposed correctly. The table on the right shows the ASA ratings which can be set on the AV-1. Figures in parentheses are film speeds which are indicated by dots on the film speed dial.
To set the ASA film speed, turn the film speed dial, while pressing the film speed dial lock button, until the ASA film speed of your film click-stops at the white index. You must reset the ASA film speed each time you load a film which has a different ASA rating.
(32) (40) (64) (80) (125) (160) (250) (320) ASA 25 • • 50 • • 100 • • 200 • • 400 (500) (640) (1000) (1250) • • 800 • • 1600
Setting the Selector Dial The selector dial has five settings. For normal photography, this dial must be set to. The dial automatically locks in this position which also allows automatic flash photography with some of the popular Canon Speedlite 133A, 155A, 177A or 199A.
The other positions on the dial are all for special uses and will be explained in more detail later. Briefly, they are: 60 : for flash photography with flashes (other than the those dedicated Canon Speedlites, check with the respective manufacturers)
B : for exposures longer than 2 seconds. Self = for self-timer photography with flashes other than the four above Canon Speedlites. A Self - for normal self-timer shooting and for self-timer flash photography with one of the four above Canon Speedlites.
To remove the selector dial from to set one of these positions, turn it while pressing the auto release button. The dial can be turned freely between the other positions.
Setting the Aperture An image is formed on the film when the film is exposed to the light at shutter release. The total amount of light allowed to strike the film is controlled by the aperture and the shutter speed. Since the AV-1 is an aperture priority AE camera, you set the aperture while the camera will automatically select the shutter speed for correct exposure The aperture is an opening formed by die phragm blades inside the lens. Each size aperture is given a numerical value called an f-number or f/stop. You can find these numbers on the lens aperture scale. The numbers on the scale differ according to the lens. A typical scale might look like this: 1.8, 2.8, 4, 5.6, 8, 11, 16, 22. Note that the smaller numbers indicate larger apertures and are called large f/stops while the larger numbers on the scale indicate smaller apertures and are called small f/stops. More info relating to this topic.
To set an aperture: With the selector dial at <\, simply turn the lens aperture ring until the desired f/stop is aligned with the aperture index. The aperture ring can also be set between f/stops. The camera will automatically select the shutter speed, according to the f/stop you have set the film speed and lighting conditions, for correct exposure.
Choosing an f/stop
Use the following table as a guide
when ASA 100 film is loaded.
1.8, 2, 2.8
Outdoor, bright sunlight
8, 11, 16
Also remember the following general rules:
1. If you want to make your subject stand out by blurring the foreground and background, use a large f/stop, such as f/2.8.
2. If you want the foreground and back~ ground to be in good focus, choose a small f/stop, such as f/11.
3. If your subject is moving and you wish to prevent blur, generally choose a large f/stop, such as f/4.
Caution: On the aperture scale of an FD lens, you will also find a green "A" or a green circle. The aperture ring can be turned to or from this mark by pressing the AE lock pin while turning the ring. When the aperture ring is set at this mark, the frame wili be exposed at the smallest aperture of the lens. Although the camera will automatically select the correct shutter speed for proper exposure, that shutter speed will probably be very slow.
This will probably lead to a blurred picture, and, since there is very little reason to use this setting, it is recommended to keep the aperture ring off this mark at all times. Please note that some FD lenses lack an AE lock pin and the aperture ring can be turned directly to the green circle. In this case, special care must be taken not to turn the aperture ring to the green circle.
