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 ﬁeld of view.

Manual exposure is also possible with the ﬁnder. In manual, the aperture scale

and shutter speed are displayed to the right of the ﬁeld of view. Thus AE and

manual modes are clearly diﬀerentiated 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.

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 ﬁnder. 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 viewﬁnder and focus the subject.

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 ﬂash or add artiﬁcial 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) ﬁlter to the lens. This

will reduce the amount of light to the ﬁlm.

Notes

If the shutter dial is set to "A" before the ﬁnder is attached, exposure information
