Overexpsoure warning zone
Underexposure warning zone
Underexposure Warning
The position of the red underexposure warning mark is determined by the lens
maximum aperture. If the meter needle points to the underexposure mark, choose
a slower shutter speed until the needle moves away from the mark.
Overexposure Warning
The red marks next to 32, 22 and 16 in the aperture scale are overexposure warning
zones. If the meter needle points to one of these zones, check the lens minimum
aperture. If, for example, the meter needle points to the red zone between f/16 and
f/22 and the minimum aperture is f/16, turn the shutter dial to a faster speed until
the meter needle points to an aperture of f/16 or larger. 31

16.2 Stopped-down (Fixed-index) Metering
1. Turn the shutter dial to the desired speed.
2. Look into the viewnder and focus the sub ject.
3. Unlock the stop-down slide. To do this, push it in and then release it; the slide
will unlock and its red line can be seen. The aperture needle will disappear
from view with the stop-down slide extended. 4. Turn the aperture ring (or shutter dial) until the meter needle is aligned with
the stopped-down metering/battery check index. Choose a slower speed if the
meter needle rests below the index, or a.faster speed if the meter needle rests
above the index.
Notes:  You can also set the aperture rst and then turn the shutter dial until the
meter needle aligns with the index. However, since intermediate settings on
the shutter dial cannot be used, minor exposure adjustments must be made
wih the lens aperture ring.  The height of the stopped-down metering index is equivalent to one-half
f/stop. 32 
						

							18 APERTURE-PRIORITY AE
17 AE Finder FN
The primary role of the AE Finder FN is to convert the camera to aperture-priority
AE or stopped-down AK. For these two modes, a shutter speed scale and, with a
New FD lens mounted, the pre-set aperture are displayed below the eld of view.
Manual exposure is also possible with the nder. In manual, the aperture scale
and shutter speed are displayed to the right of the eld of view. Thus AE and
manual modes are clearly dierentiated and you know immediately in which mode
the camera is set simply by the location of the exposure information.
Focusing Screen FN-AE, which provides center-weighted average metering, is sup-
plied when the New Canon F-1 is purchased initially with an AE Finder FN.
18 Aperture-priority AE 1. After attaching the AE Finder FN, set the shutter dial to A. To do this,
pull up the outer ring and turn the dial until A is aligned with the index
on the nder. The shutter dial cannot be turned between the A and B
settings. 2. Turn the lens aperture ring to the desired aperture.
3. Look into the viewnder and focus the sub ject.
4. Turn the meter mode selector to A. Then press the shutter button halfway
to turn on the meter. Exposure will be correct as long as the meter needle is
not pointing to either of the exposure warning zones. If the meter needle is
in either zone, turn the aperture ring until it moves out of the zone. 5. To release the shutter, press the shutter button all the way down.
There is a possibility of camera movement if the meter needle indicates a shutter
speed of 1/30 sec. or slower. In this case, choose a larger aperture until the shutter
speed indicated is 1/60 sec. or faster. If you have set the maximum aperture and
the shutter speed is still slower than 1/60 sec., attach the camera to a tripod, use
a 
ash or add articial light.
On the other hand, if the meter needle indicates over exposure even after you have
set the m n mum aperture, attach a neutral density (ND) lter to the lens. This
will reduce the amount of light to the lm.
Notes
If the shutter dial is set to A before the nder is attached, exposure information 33 
						

							18 APERTURE-PRIORITY AE
will not be displayed. In this case, rst turn the shutter dial to 2000, then back
to A. Notes:
 Exposure information will not be displayed with a dierent nder attached
and the shutter dial set on A.  With a New FD lens without chrome mount ring), the aperture is displayed
adjacent to the shutter speed scale in the viewnder. It is impossible, however,
to read the aperture when using an FD lens with a chrome mount ring or when
using an extender, extension tubes or other close-up accessories between the
camera body and lens. 34 
						

							18 APERTURE-PRIORITY AE 18.1 Stopped-down AE
 If your eye will not be to the eyepiece the moment you release the shutter,
close the eyepiece shutter by pushing the lever clockwise. This will prevent
stray light from entering and adversely aecting the exposure. 18.1 Stopped-down AE
1. Following the procedure on p. 40, set the shutter dial to A.
2. Look into the viewnder and focus the sub ject.
3. Turn the lens aperture ring to the desired aperture.
4. Unlock the stop-down slide. To do this, push it in and then release it; the
slide will unlock and its red line can be seen. 5. The shutter speed is automatically selected according to the aperture set on
the aperture ring.
If the meter needle is in either exposure warning zone, turn the aperture ring
until the needle moves out of the zone.
Overexposure, underexpd ture and camera shake warnings are the same as for aper-
ture priority AE. 35

18.2 Match-needle Metering
To meter the sub ject manually, simply disengage the shutter dial from A. The
shutter speed scale will disappear, and the aperture scale and shutter speed display
will appear to the right of the eld of view. Then set the shutter speed and aperture
in the usual manner, matching the meter and aperture needles in the viewnder.
18.3 Stopped-down (Fixed-index) Metering
Although stopped-down AE is a much simpler and faster method of metering, you
can still use xed-index stopped-down metering. 36

Note
Use of the following accessories is limited when the AE Finder FN is at-
tached:  Early TS 35mm f/2.8 lenses: The fens shift knob will touch the nder as you
rotate the lens, preventing full rotation.  Early Auto Bellows: The nder will touch the bellows rear standard as you
rotate the camera, making vertical shots impossible.
For details concerning modication of either accessory, please contact the nearest
Canon authorized service facility. 37 
						

							19 SHUTTER-PRIORITY AE
19 Shutter-priority AE
When the AE Power Winder FN or AE Motor Drive FN is attached to the New
Canon F-1, a choice of shutter-priority AE or manual exposure is available according
to the shooting situation and your personal preference. For shutter-priority AE, simply turn the lens aperture ring to the A mark and
turn the shutter dial to the desired speed. The aperture scale and the shutter
spee `which you have selected are displayed, as in match-needle metering, to the
right of the eld of view. The aperture needle, however, disappears from view.
When you press the shutter button halfway, the meter needle will point to the aper-
ture which the camera has selected automatically. If the meter needle points to
either the over- or underexposure warning mark, simply turn the shutter dial until
the needle moves away from the mark.
With both the AE Finder FN and the power winder or motor drive attached, any of 38 
						

							19 SHUTTER-PRIORITY AE
the various exposure modes can be used. For aperture-priority AK, rst disengage
the lens aperture ring from the A mark. Then set thg shutter dial to A, and
manually select an aperture. The camera will select the shutter speed automati-
cally.
For manual exposure, make sure that both the lens aperture ring and the shutter
dial are disengaged from the A setting. Then set the shutter speed and aperture
manually, aligning the two needles in the viewnder in the usual way.
For further details, see the power drives instructions.
Note
In general, center-weighted average metering is recommended for AE photography.
Please see p. 48 for further details. Socket Covers
There are three socket covers in the baseplate of the camera. All three must be
removed to attach the motor drive; for the power winder, only two (2) and (3) must
be removed. Do not remove them unless you intend to attach one of these AE power
drives. Above all, NEVER remove the rewind coupler cover (1) when lm is loaded
in the camera or the lm will be exposed to light.
CAUTION  Do not set both the shutter dial and the lens aperture ring to the A set-
tings.Otherwise, the lens will stop down to the smallest aperture and the
camera will operate in aperture-priority AE. Depending on the lighting con-
ditions, this may result in undesirably slow shutter speeds. 39 
						

							19 SHUTTER-PRIORITY AE
 After removing the power winder or motor drive, do not forget to remove the
lens aperture ring from the A mark or the shutter will not release when
you press the shutter button.  Before attaching the nder or motor drive, wipe the contacts with a clean,
dry cloth to prevent poor contact from dirt. 40
