28 Flash Photography
28.1 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 viewnder; as soon as the meter needle points to the auto working aperture,
the 
ash 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 61

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 automatically switches back to the speed
actually set on the shutter dial until the Speedlites pilot lamp glows again.
28.2 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 
ash photography is that the background in
the picture will be lighter. You can choose among three working apertures on each
of these Speedlites for optimum control of depth of eld. For this technique, rst
set the AUTO/MANU switch of the Speedlite to MANU. Then turn the cameras
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 
ash will re at the release of the
rst shutter curtain. If the shutter dial is set to a speed from 1/2000 to 1/125sec.
or S, the shutter speed will automatically switch to 1/90 sec. As in normal AE

ash 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 
ash unit, make sure its power switch is OFF.
Note
If using a viewnder which does not have an accessory shoe, such as the Waist-Level
Finder FN connect the Speedlite to the cameras 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 
ash unit. 62

28.3 General Flash Photography
When using an automatic 
ash unit other than a Canon Speedlite, rst turn the
shutter dial to  ~ (1/90 sec) Then turn the aperture ring to the same aperture
which you have set on the 
ash. With the shutter dial on  f , other types of
electronic 
ash units can be synchronized either through the hot shoe or via the PC
socket on the side of the camera. These allow two separate 
ash units to be red
simultaneously. Set the shutter dial according to the information in the table on
the following page.
When shooting with a 
ash bulb or a manual 
ash unit, calculate the aperture with
a guidenumber formula or with the calculator dial if the 
ash unit has one. Turn
the lens aperture ring to that aperture.
CAUTION
It is recommended to use a Canon 
ash unit on this camera. Using a 
ash or 
ash
accessory of another make may cause the camera to work improperly or even possi-
bly damage the camera itself. If you use a non-Canon 
ash. turn o the unit before
YoU attach it to or remove it from the cameras hot shoe. Before removing the 
ash,
press the 
ash 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 
ash unit. 63

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 lm. 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 lm, visible light must be kept out by means of a deep red
lter, such as an R1 or Kodak Wratten 87. The position of the infrared index mark
has been computed for the use of infrared lm with peak sensitivity at 800nm, such
as Kodak IR 135.
For further details, refer to the lm manufacturers instructions. 64

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.  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.  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).  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, rst 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 diers according to the type of lens. 67

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 counterclock-
wise 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 di-
rectly 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 68 
						

							29 SHOOTING WITH CLOSE-UP ACCESSORIES
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 lm plane. It is useful for measuring the exact shooting distance from lm to
sub ject 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 Ex-
tenders FD 2x and FD 1.4x, which are designed for normal full-aperture metering. 69
