13 EXPOSURE MODES
13 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) s imply 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 Full-aperture Metering
With a Canon FD lens, metering is done with the lens at maximum aperture. This
is called ”full-aperture metering.” The lens diaphragm do es not close down until the
shutter is released. Afterwards, it reop ens automatically to the maximum aperture.
One of the primary advantages of f ull-aperture metering is that you are able to view
and meter the subject with the viewfinder at its brightest.
1. Match-needle Meter ing
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.
