Double-Check Before Shooting If you hurry to release the shutter, you may make an

unexpected error due to carelessness. The following points should be double checked:

1) Is the aperture ring of the lens se to the "A" mark?

Press in the EE lock pin while turning the aperture ring to the "A" mark. This specific setting

is a requisite for beautiful color pictures with automatic exposure. If you fail to adjust the

aperture ring to this setting when appropriate, the correct automatic exposure will not be

obtained. When the aperture ring of the lens is not set to the "A" mark, the manual aperture

control "M" signal above the aperture scale in the viewfinder flash has on and off as a warning

that the aperture ring is not set at the "A" setting.

2) Did you set the film speed properly?

It is necessary to set the film speed properly according to the film in use in order to obtain the

correct exposure.

3) Is the film properly loaded?

You can use the rewind knob as an indicator that the perforations of the film are properly

engaged on the sprocket and the film is actually advancing. Every time you advance the film,

the rewind knob should turn.

Detailed Operation of the AE-1

A silicon photocell is used as the photosensitive element in the camera. If you compare the

silicon photocell (SPC) with other existing photo-sensitive elements, you will find it covers a

greater range of lighting situations and allows for greater accuracy. In order to provide the

AE-1 with the best possible magnetic release system, Canon developed a special circuit for

instantaneous light metering, Due to this innovation, even in place as dark as EV1 (at ISO

100, f/1.4, 1 sec.), metering can be performed in only 0.04 second.

Meter Sensitivity Pattern

In a great variety of lighting situations, the carefully designed Central

Emphasis Metering system simplifies problems to ensure that the subject is

correctly exposed.
