Canon Eos 3 Owners Manual

							3. Using Non-Canon Flash Units
Sync Speed
The EOS-3 can synchronize with compact, non-Canon flash units at
1/200 sec. or slower shutter speeds. With large studio flash, the sync
speed is 1/125 sec. or slower. Be sure to test the flash to see if it
synchronizes properly with the camera.
PC Terminal
The camera’s PC terminal is provided for flash units using a sync cor\
d.
The PC terminal is threaded to prevent inadvertent disconnection. Only X\
-
sync is used for synchronization at 1/200 sec. or slower.101
A flash unit attached to the camera’s hot shoe and a flash unit conne\
cted to the PC
terminal can be used at the same time.
•Canon EOS-dedicated Speedlites are recommended for use with this camera.\
•If the camera is used with a flash unit or flash accessory dedicated to \
another
camera brand, the camera may not operate properly and camera malfunction\
 may
result.
• There are studio flash units whose
sync cord polarity is opposite from
the camera’s PC terminal. Such
flash units do not work with the
camera. Consult the manufacturer of
the flash unit or purchase a
commercially-available polarity
conversion cord. The camera’s PC
terminal polarity is shown in the
figure on the right.

●Depth of Field
This is the range in front of and behind the plane of optimum focus
where acceptable focus can be achieved. The smaller the aperture (the
larger the F-number), the greater the depth of field will be. And the
larger the aperture (the smaller the F-number), the shallower the dept\
h
of field will be.
The depth of field is affected as described below:
(1) A smaller aperture (a larger F-number) increases the depth of field.
(2) A lens with a shorter focal length increases the depth of field. ...A wide-angle lens obtains a greater depth of field than a telephoto
lens.
(3) A longer distance between the camera and subject increases the depth of field.
(4) The depth of field behind the plane of optimum focus is twice as
long as the depth of field in front of the plane of optimum focus.

left-most increment (–3) is for Custom
Function CF-1. The next increment to the
right denotes the next Custom Function in
numerical order up to CF-17.

Remarks Page
This is convenient if you develop the film yourself.
• If 1 is set, the shutter speed will always be 1/8000 sec. if you release\
the shutter with the camera back open.
This is effective if you want to set the film speed yourself.
You can be relieved from setting the film speed each time you load film.\
This is effective when you want to focus and meter at different portions\
 of
the scene.
This is effective when you want to stop AI Servo AF operation
momentarily.
If an obstruction comes between the camera and subject, it will not thro\
w
off the AF. The exposure is set at the moment of exposure.
When you use AI Servo AF, you can toggle between AI Servo AF and focus
lock just by pressing the < > button. This is useful for subjects which keep
moving and stopping repeatedly. The exposure is also set at the moment
when the picture is taken. Thus, the focusing and exposure are always se\
t
correctly and all you do is wait for the right moment to capture the sho\
t.
