Eye-Level Finder FN

With the Eye-Level Finder FN, an aperture scale and the pre-set shutter speed are displayed to the right of the field of view. Focusing Screen FN-PE, which offers selective-area metering, is supplied with the New Canon F-1! Eye-Level Finder combination.

I. Match-needle Metering
1. Turn the shutter dial to the desired speed.
2. Look into the viewfinder and focus the subject.
3. Place your subject so that it fills the rectangular area in the center of the viewfinder. This shaded portion is the light measuring area of the camera's silicon photocell and is 12% of the field of view.
4. Turn the meter mode selector to the desired mode. Then lightly press the shutter button halfway to turn on the meter.
The meter needle should be outside of the exposure warning zones. If it is in either zone, turn the shutter dial until the meter needle moves out of the zone.
5. For correct exposure, turn the lens' aperture ring until the center of the aperture needle aligns with the meter needle. The diameter of the circle is equivalent to one f/stop, and exposure adjustment is possible in one-half f/stop increments simply by turning the lens' aperture ring.

one f/stop
one-half f/stop

Notes
1. The aperture needle moves only between the minimum and maximum apertures of the lens in use.
2. The meter does not operate with the shutter dial on "B" or " i."

Overexposure warning zone
 
Under 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 t~te 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.

II. Stopped-down (Fixed-index) Metering
1. Turn the shutter dial to the desired speed.
2. Look into the viewfinder and focus the subject.
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
1. You can also set the aperture first 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.
2. The height of the stopped-down metering index is equivalent to one-half f/stop.
