13 EXPOSURE MODES

Exposure Modes

The New Canon F-1 is basically a manual-exposure camera capable of through-the-

iens, full-aperture metering and stopped-down metering with the Eye-Level Finder

FN. It can be converted to automatic exposure (AE) simply by attaching the suit-

able AE accessory, such as the AE Finder FN for aperture-priority AE, or the AE

Power Winder FN or AE Motor Drive FN for shutter-priority AE. Manual exposure

is still possible with one or both of these accessories attached.

The following exposure modes are possible with the New Canon F-1:

Match-needle Metering

Shutter-priority AE

Aperture-priority AE

Stopped-down (Fixed-index) Metering

Stopped-down AE

Detailed information of these modes is provided in the sections entitled "Eye-Level

Finder FN," "AE Finder FN," and "Shutter-priority AE."

13.1

With a Canon FD lens, metering is done with the lens at maximum aperture. This

is called "full-aperture metering." The lens diaphragm does not close down until the

shutter is released. Afterwards, it reopens automatically to the maximum aperture.

One of the primary advantages of full-aperture metering is that you are able to view

and meter the subject with the viewﬁnder at its brightest.

1. Match-needle Metering

Set the desired shutter speed and turn the lens' aperture ring until the meter needle

bisects the aperture ring. The position of the meter needle is determined by the

ﬁlm speed, shutter speed and the lighting conditions. This manual mode is suitable

for virtually all subjects.

2. Shutter-priority AE

Set the desired shutter speed and the camera automatically selects the proper aper-

ture according to lighting conditions. This AE mode is suitable for most subjects

but especially useful in action photography.
