Tripod and Cable Release

A tripod and cable release will be indispensable whenever the shutter speed is very slow such as in night shooting and indoor shooting without flash. Unless you are using a suitable shutter speed for hand-held telephoto shooting, a tripod at least should also be used with a telephoto lens.

A cable release is a device which screws into the camera's shutter button and allows the shutter to be released without your having to touch the shutter button itself.



If the camera platform of the tripod is quite large, it may be difficult to turn the focusing and aperture rings unless Tripod Adapter A is inserted between the camera and the platform. Tripod Adapter A is an optional accessory.

If you don't have a tripod and a cable release, you might get satisfactory results by placing the camera on a steady support, such as a railing or a table, and using the camera's self-timer to release the shutter.

Self Timer

The AV-1 has a self-timer which allows you to include yourself in the picture. It may also be used instead of a cable release in many instances when you would normally use a cable release. To use the self-timer for normal photography or for automatic flash with the Canon Speedlite 133A, 155A, 177A or 199A, set the selector dial to "A Self".

Set an aperture as usual, check the exposure, slide the viewfinder cover into the eyepiece grooves and press the shutter button.

Since the camera sets the exposure as soon as the button is depressed, do not stand in front of the camera while you press the shutter button or exposure will be incorrect.

The shutter will be released automatically ten seconds after you press the shutter button. During the first eight of those seconds, the self-timer lamp will blink on and off at a rate of two flashes per second to indicate that the self-timer is working.

During the last two seconds the blinking rate will increase to eight times per second to warn of impending shutter release.

For self-timer shooting with flashes other than the four Canon Speedlites, set the selector dial to "Self ~ " and proceed as above. The selector dial click-stops at the "A" and " " positions of the "Self" setting. Do not set the dial between those two positions.

The self-timer can be cancelled before shutter release by pressing the battery check button (right).

Viewfinder Cover

The viewfinder cover should be slipped over the eyepiece whenever pictures wili be taken when your eye is not to the eyepiece. Otherwise stray light entering the viewfinder through the eyepiece may cause underexposure.

This applies to self-timer shooting and often to tripod or copy stand work and is especially important in night shooting. When not in use, the viewfinder-cover may be slipped into the camera's accessory shoe.

Shooting Indoor with Flash

Of course, you can often take pictures indoors without flash, but usually it is too dark. Generally, if the meter needle points to or below the camera shake warning index when you check the exposure, the best thing to do is to mount a flash.

With Canon Speedlite 133A, 155A, 177A or 199A

Automatic flash photography is possible with the Canon Speedlite 133A, 155A, 177A or 199A when the selector dial is set to < A >.

With Instruction Manuals Links

The procedure with the Speedlite 155A is as follows:

1.Load the batteries into the flash. The battery poles and flash contacts should be wiped with a clean, dry cloth before loading to prevent possible corrosion or damage to the flash.
2. Insert the Speedlite into the camera's accessory shoe.
3. Set the ASA film speed on the flash.
4. Make sure the AV- 1's selector dial is at < A > (This will automatically set the shutter speed to the X-synchronization speed of, 10 sec. when the pilot lamp glows).
5. Set the
AUTO/MANU. switch to either the green or red AUTO position and read the corresponding aperture from the calculator dial.
6. Set that same aperture on the lens aperture ring.
7. Switch the flash on.
8. Focus the subject and check the lens' distance scale to make sure you are within the auto working range. This is the permissable range of shooting distances which the flash indicates for the aperture you have chosen.
9. Wait for the pilot lamp to glow. At that point, the meter needle in the viewfinder will automatically point to the shutter speed of 10 sec. (when the shutter button is pressed halfway).
10. Press the shutter button all the way for flash exposure.

The camera reverts to normal aperture-priority AE photography during flash intervals when the pilot lamp goes out. This allows you to shoot continuously while automatically switching from flash shooting to normal shooting. When the flash is switched off, you can also shoot normally while the flash is still mounted on the camera. Automatic flash photography is also possible when the selector dial is set to "B". In this case, the shutter will remain open as long as you press the shutter button and the flash will be synchronized with the opening of the first shutter curtain. This is useful for lightening the background of the subject. At this setting, the camera will not automatically switch to normal aperture priority AE during flash intervals. Use of the 133A, 177A and 199A on the AV-1 is very similar. Setting the 199A's shutter speed selector switch to MANU. for the use of slower synchronization speeds is not possible with this camera.

With Other Flash Units (60 sec) The flash must be designed to synchronize with the camera's shutter at a speed of 60 sec. Set the AV-1's selector dial to 60: This will set the shutter speed to 60 sec. For special effects, the selector dial may be set to "B" instead of 60 .

When using an automatic electronic flash, set the lens aperture ring to the same f/stop set on the flash unit. Follow the flash instructions.

Manual flash photography is also possible with the AV-1. Follow the instructions of the flash.
Note: Flashbulbs cannot be used on this camera. Canon claimed the AV-1 is recommended to use a Canon flash unit on this camera. Using a third party flash or flash accessory of another make may cause the camera to work improperly or even possibly damage the camera itself.

Using older Canon FL lenses and other close-up accessories

Stopped-down Metering

When an FD lens is mounted directly on the camera, you will notice that the diaphragm remains fully open at the maximum lens aperture until you press the shutter button. At that point it ciQses or "stops" down to the "working" aperture, i.e., the aperture you have set on the lens.

Following shutter release, it automatically reopens to full aperture. Even though metering is done at full aperture, the meter knows which aperture you have set on the lens because it is given that informa tion by one of the levers at the rear of the lens. Consequently, the camera is able to set the shutter speed according to the "working" aperture even when the diaphragm is fully open. This is also called full-aperture metering. Whenever you use an FL lens or any other non-FD lens, such as the TS 35mm lens or the Fish-eye 7.5mm lens, full-aperture metering is not possible. It is also not possible whenever any accessory is inserted between the camera and any lens for extending the lens focal length or for increasing lens extension in close-up shooting. In these cases, in order for the camera to set the correct shutter speed, the lens must actually be stopped down to the working aperture while metering. This is called stopped-down metering. The only exceptions to this rule are the intermediate accessories, Extenders FD 2x-A, FD 2x-B and Extension Tubes FD-U, which permit normal full-aperture metering. When an FL or other non-FD lens is mounted directly to the camera, stopped-down metering is automatic. That is, the diaphragm opens or closes to the working aperture for metering as you turn the aperture ring. You will notice this as a lightening or darkening in the viewfinder as you turn the aperture ring. The same thing will happen when an automatic accessory is inserted between the camera and lens. When using a manual accessory or a macrophoto coupler with an FD lens, however, the diaphragm will not open and close with rotation of the aperture ring until the lens is set for manual diaphragm control. Even though metering takes place at the working aperture, the shooting procedure is exactly the same as for normal AE photography as described in "General Usage". Simply set an aperture on the aperture ring, and the camera will set the shutter speed automatically for correct exposure. No special setting is necessary on this camera for stopped-down metering. For normal shooting, the selector dial should tee set to <A>. When using an FL lens on this camera, with or without close-up accessories, always set the A-M ring on the lens to the "M" position. For easier focusing in stopped-down metering, whether with FL and special lenses or with close-up accessories, set the aperture ring to the largest f/stop for focusing and then set it to the f/stop you want for metering and taking your shot.

Note that, when the lens is stopped-down, you can visually check the extent of depth of field by simply inspecting the subject through the viewfinder at the working aperture. When using the AV-1's through-the-lens meter, no exposure correction is necessary when using close-up accessories.
