Flash Photography

I. AE Flash Photography with Speedlites 011A, 133A, 155A, 166A, 177A, 188A, 199A, 533G and 577G.


Once the Speedlite is attached to the camera and its pilot lamp is glowing, the camera switches automatically to the X sync speed of l/90 sec. provided the shutter dial is not on "B."

In addition, the meter needle points simultaneously to the aperture which you have set on the back of the Speedlite. Thus you do not have to take your eye away from the~viewfinder; as soon as the meter needle points to the auto working aperture, the flash is ready. Now simply turn the lens' aperture ring until the aperture needle aligns with the meter needle.

With the AE Finder FN attached and the shutter dial on "A," the camera will switch automatically to the X sync speed of 1/90 sec. and the meter needle will point to the right of 1/60 sec. Set the same aperture on the lens as that set on the Speedlite.

With the power winder or motor drive attached and the lens' aperture ring set to the "A' mark for shutter-priority AE, the camera will automatically switch the shutter speed to 1/90 sec. and the aperture to the f/stop which you have set on the Speedlite as long as the shutter dial is not on "B."

After the shutter is released, the camera automati~cally switches back to the speed actually set on the shutter dial until the Speedlite's pilot lamp glows again.

II. Slow-sync Flash Photography

With Speedlites 199A, 533G and 577G, you can select a shutter speed slower than 1/90 sec. The advantage of slow-sync flash photography is that the background in the picture wiU be lighter. You can choose among three working apertures on each of these Speedlites for optimum control of depth of field. For this technique, first set the AUTO/MANU switch of the Speedlite to "MANU." Then turn the camera's shutter dial to any speed from 1/60 sec. to 8 seconds. The picture will be taken at the speed you have set on the shutter dial and the flash will fire at the release of the first shutter curtain. If the shutter dial is set to a speed from 1/2000 to 1/125sec. or "`," the shutter speed will automatically switch to 1/90 sec. As in normal AE flash photography, the meter needle will point to the aperture which you~have set on the Speedlite as soon as the pilot lamp lights up. Simply turn the aperture ring until the aperture needle matches the meter needle.

With the motor drive or power winder attached and the lens' aperture ring set to the "A" mark, the aperture will be controlled automatically as well.

IMPORTANT

Before mounting a flash unit, make sure its power switch is OFF.

Note

If using a viewfinder which does not have an accessory shoe, such as the Waist-Level Finder FN connect the Speedlite to the camera's PC socket via a synchronization cord. Then turn the shutter dial to "t" (1/90 sec.) and set the same aperture on the lens as that set on the flash unit.

III. General Flash Photography

When using an automatic flash unit other than a Canon Speedlite, first turn the shutter dial to " ~ " ( 1/90 sec~ Then turn the aperture ring to the same aperture which you have set on the flash. With the shutter dial on " f ," other types of electronic flash units can be synchronized either through the hot shoe or via the PC socket on the side of the camera. These allow two~ separate flash units to be fired simultaneously. Set the shutter dial according to the information in the table on the following page.

When shooting with a flash bulb or a manual flash unit, calculate the aperture with a guidenumber formula or with the calculator dial if the flash unit has one. Turn the lens' aperture ring to that aperture.

Shooting Distance

When calculating, make sure that the guide number and shooting distance are both in the same unit, whether meters or feet.

Manual flash photography is possible with Speedlites 1 55A, 1 77A, 1 88A, 1 99A and 577G. With any of these flash units, the shutter speed will switch automatically to 1/90 sec. as soon as the pilot lamp lights up, provided the shutter dial is not on "B." The meter needle however, will not point to the auto working aperture as in normal AE flash; instead, it will point to the overexposure warning zone. Since the meter needle does not indicate that the flash is charged, check the pilot lamp to make sure it is glowing before you shoot. Following the procedure above, manually set the aperture on the lens.

For more details, see the instructions of the flash.

CAUTION

It is recommended to use a Canon flash unit on this camera. Using a flash or flash accessory of another make may cause the camera to work improperly or even possibly damage the camera itself. If you use a non-Canon flash. turn off the unit before YoU attach it to or remove it from the camera's hot shoe. Before removing the flash, press the flash test button if it has one to discharge any power remaining in the capacitor. These are merely precautions; following these steps will not necessarily prevent the camera from being damaged by the flash unit.


Infrared Index Mark

Infrared light has longer wavelengths which focus on a plane slightly behind that of ordinary visible light. It is necessary, therefore, to slightly adjust the focus of the lens when using blackand-white infrared film. The infrared index mark engraved on the lens is used for this purpose. After focusing in the usual way, note the small red dot engraved on the lens barrel to the right of the distance index, and turn the focusing ring to align the focused distance with this dot. For instance,if the focus is at 1 Om on the distance scale,turn the focusing ring to align the10m mark with the red dot. After making this correction, you can release the shutter. When using black-and-white infrared film, visible light must be kept out by means of a deep red filter, such as an R1 or Kodak Wratten 87. The position of the infrared index mark has been computed for the use of infrared film with peak sensitivity at 800nm, such as Kodak IR 135.

For further details, refer to the film manufacturer's instructions.


Shooting with Close-up Accessories

With few exceptions (noted in the instructions for the accessory), stopped-down metering is necessary whenever you insert an accessory between the camera and lens for close-up photography.

1. If you insert an accessory designed for AUTOMATIC diaphragm control, such as the Auto Bellows or Bellows FL, between the camera and ANY lens, follow the steps for stopped-down metering.
2. If you insert an accessory designed for MANUAL diaphragm control, such as M Extension Tubes or Bellows M, between the camera and a NON-FD lens, follow the steps for stopped-down metering. Turn the A-M ring of an FL lens to "M" for taking the shot (not necessary if Canon Macro Auto Ring and Double Cable Release are used).
3. If you insert in accessory designed for MANUAL diaphragm control between the camera and an FD lens, unless you use the Canon Macro Auto Ring and Double Cable Release, first set the lens for manual diaphragm control before mounting it on the accessory. Then follow the steps for stopped-down metering.

Note

The instructions with the accessory will tell you whether or not manual diaphragm control is necessary. The procedure differs according to the type of lens.

Manual Diaphragm Control

FD Lenses without Chrome Mount Ring except for FD Macro Lenses

1. 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 counterclockwise and lower the adapter into the groove.

2. Mount the lens on the accessory.
The diaphragm blades will now open or close as you turn the aperture ring.
When the manual diaphragm adapter is attached, never mount the lens directly on the camera or on an accessory designed for automatic diaphragm control, such as the Auto Bellows or Bellows FL.

FD Lenses vvith Chrome Mount Ring and FD Macro Lenses (except for FD 200mm f/4 Macro Lens)

1. Push the automatic aperture lever at the rear of the lens countesclockwise until it automatically locks.
2. Mount the lens on the accessory.

Note

Some of these lenses have an additional lock lever. With these lenses, push the automatic aperture lever fully counterclockwise, then push the lock lever to "L"


Be sure to reset the automatic aperture lever to its normal position before mounting the lens directly on 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, engraved on top of,-the camera body, indicates the exact position of the film plane. It is useful for measuring the exact shooting distance from film to subject in closeup photography. Distances on the lens' distance scale are calibrated from this mark. It is not used in general photography.

Note

The aperture ring of an FD lens must be removed from "A" before you mount the lens on any of these close-up accessories except for FD-U Extension Tubes and Extenders FD 2x and FD 1.4x, which are designed for normal full-aperture metering.
