Manual Diaphragm Control The insertion of manual accessories or a macrophoto coupler between the camera and an FD lens requires setting the lens for manual d iaphragm control before stopped-down meter" ing is possible. The instructions for the various accessories involved will tell you whether or not this is necessary.

All FD lenses which lack a chrome mount ring, with the exception of the Macro lenses, are set for manual diaphragm control as follows:


1
. Before mounting the lens, insert the slot of the accessory manual diaphragm adapter over the tip of the automatic aperture lever at the rear of the lens. Push the lever to the right and lower the adapter into the groove to lock the lever in that position.

2. Mount the lens onto the accessory. The diaphragm will now open and close as the aperture ring is rotated.


When the manual diaphragm adapter is attached on the rear of one of these lenses, never mount the lens directly on the camera or directly on accessories designed for automatic diaphragm control, such as the Auto Bellows or Bellows FL.

All chrome-mount-ring FD lenses and FD Macro lenses are set for manual diaphragm control as follows:

mount1.jpg mount2.jpg mount3.jpg mount4.jpg


1
. Before mounting the lens, push the automatic aperture lever at the rear of the lens to the right where it automatically locks.
2. Mount the lens onto the accessory as usual. The diaphragm will now open and close as the aperture ring is rotated.

Some of these lenses have an additional lock lever. With these lenses, the automatic aperture lever must be pushed fully to the right and the lock lever pushed to " L" to hold the automatic aperture lever in that position.

Note:
*
When using a macrophoto coupler, the Macro Hood must also be mounted onto the rear of the lens.
** You may avoid setting the lens for manual diaphragm control when using manual accessories or a macrophoto coupler by attaching the Canon Macro Auto Ring and/or Double Cable Release.
*** Be sure to reset the automatic aperture lever to its normal positioh before using the lens once more in direct contact with the camera. In the case of a lens with a lock lever, switch it back to the position of the white dot.

Film Plane Indicator

This mark is engraved on the top of the camera just to the right of the rewind knob to indicate the exact position of the film plane.

It is not used in general photography, but it is helpful in close-up photography for obtaining the exact shooting distance from film to subject.


Infrared Index Mark

Since infrared light rays have longer wavelengths which focus on a plane slightly behind that of ordinary visible light rays, it is necessary to slightly adjust the focus of the lens when using black and white infrared film. The infrared index mark engraved on the lens barrel is used for this purpose.

After focusing the same as usual, note the tiny red dot engraved on the lens barrel just to the right of the distance index, and turn the focusing ring to atign the focused distance with this red dot.


For instance, if the focus is at 5m on the distance scale, turn the focusing ring to align the 5m mark with the red dot. After that focusing correction, you can release the shutter.

When using infrared black and white film, visible light rays must be kept out by means of a deep red filter (R1) over the lens. When using infrared color film, there is no need to make a focusing correction. Fol low the detailed instructions of the film manufacturer.

The position of the infrared index mark has been computed for the use of infrared film with peak sensitivity at 880nm (Such as Kodak IR 135) and a red filter such as Wratten

A-Series System Accessories


The AV-1, along with the A-1, AE-1 and AT-1, is one of Canon's A-series cameras. Like these cameras, it accepts most of the A-system accessories. These are the Speedlites 133A, 155A, 177A and 199A and the Power Winder A. With these accessories, the AV-1 will do its best in poor lighting and fast-action shooting.

Speedlites 133A, 155A, 177A and 199A | Speedlites |

Any of these flashes slips easily into the AV-1's accessory shoe where it permits automatic flash photography. The shutter speed is set automatically while you simply set the same aperture on the lens as you have set with the flick of a switch on the flash. With only one flash aperture, f/4, for films having a speed of ASA 80, 100 or 400, use of the Speedlite 133A is especially easy. Both the Speedlite 155A and 177A offer a choice of two apertures, f/2.8 and f/5.6, with ASA 100 film while the Speedlite 199A offers one more,

Power Winder
| Winder A | Winder A2 |

The Power Winder A attaches to the AV-1 with a turn of a screw where it matches the camera's compactness to a tee. It gives a choice of two modes: single-frame shooting with automatic film winding or continuous shooting in which the film is wound and the shutter recocked automatically at about two frames per second. Either way, the power winder couples with the AV-1 at any shutter speed from 2 sec. to 1000 sec.

This is an extremely popular accessory which is especially handy for taking sequential action shots, as in sports and fashion photography.

As you become more familiar with the AV-1, you may find your interest in photography growing and feel like expanding a bit. After a while, you may be searching for a new look in your photos. As simple as the AV-1 is to use, it is a full-fledged SLR camera and accepts most of Canon's SLR system accessories.

Macro Accessories.jpg
Besides a choice of nearly fifty FD and special lenses, all of which are world-renowned for their high performance, you have the pick of about thirty more accessories for close-ups, photomacrography and photomicrography.


From close-up lenses to three bellows units, copy stands to Photomicro Unit F, Canon offers all the equipment you need for unparalleled results. It's easy to expand with the AV-1.

When you find yourself in unusual shooting situations, Canon again has all the answers. In problematic viewing situations, Angle Finder A2 or B may come in handy. Angle Finder A2 shows the image in reverse left-toright; Angle Finder B's image is completely correct.


A Dioptric Adjustment Lens S is a big advantage for eyeglass wearers. When very precise focusing is important, try Magnifier S. Cable Release 30 or 50 or the Double Cable Release would be a good, inexpensive accessory to have on hand, and take a look into Canon filters. A UV or Skylight filter, in particular, would be an excellent, generalpurpose lens accessory. Enjoy.

USING THE CAMERA IN EXTREMELY LOW TEMPERATURES

In extremely iow temperatures, always protect the camera from outside air and try to finish shooting as quickly as possible. In temperatures below 0°C (32 F), the battery may be affected, so you may want to carry a spare. Keep the camera~ and spare battery close to your body or in a pocket to keep them warm until you are ready to take a picture. Although the battery may not function well in low temperatures, don't throw it away. It may work perfectly again when you use the camera in warmer temperatures.

Avoid extreme temperature changes. Condensation forming on a camera and lens: taken from cold temperatures into a warm room may cause corrosion. Let the camera gradually adjust to the temperature change by placing it in a completely sealed plastic bag for awhile.

Care and Maintainance

The AV-1 is a rugged, high-quality camera. It will work properly if operated and cared for properly. Never force anything. If you have a problem that is not answered in the instructions below, follow the advice of your nearest Canon serviceman. We recommend taking the AV-1 to an authorized Canon service facility at least once every three years for a complete checkup.

Storage

The best thing you can do for your AV-1 is to use it regularly, but in the event that it won't be used for quite a while, first remove it from any camera bag or soft case. Then remove the battery to prevent possible corrosion to the terminals. Recap the lens, and if the body is stored separately from the lens, put the body cap and the rear lens cap on. Wrap it in a clean, soft cloth and store it in a cool, dry, dust-free place. Avoid storing it in the rearwindowshelf,glovecompartmentor other "hot spots" of an automobile, in a place such as a laboratory where chemicals could cause corrosion and rust, or in a dusty, damp, or hot place. Keep it out of direct sunlight. Before using the AV-1 after it has been stored for a long time, carefully check the operation of each part.

Cleaning

First blow off dust on the camera with a blower brush. You may use a silicone cloth or chamois leather to wipe smudges off the camera body. Do not use such cloths on the lens surface, eyepiece or inside the camera body. To clean the eyepiece, first blow dust off with a blower brush, then put a drop or two of lens cleaning fluid on camera lens tissue and wipe off any smudges. If the mirror gets dirty, it will not affect the picture although it may make it hard to see.
NEVER touch the mirror. Blow off dust very gently with a blower brush. If more cleaning is necessary, do not attempt to do it yourself but take the camera to an authorized Canon service facility. The film compartment also requires occasional cleaning with a blower brush to remove accumulated film dust particles which might scratch the film. While doing this take special care NEVER to press on the shutter curtain, the rail surfaces or the pressure plate. For details on how to clean the lens, follow the lens instruction booklet very carefully. Only use cleaning fluid and lens tissue manufactured especially for camera lenses.

Salt and sand are your camera's worst enemies. After using it on a beach, clean it thoroughly. If you accidentally drop it in the water, it will probably be irreparable but take it immediately to an authorized Canon service facility or any qualify service centre.
