Viewing and Focusing
The Canon EF is a single-lens-reflex (SLR) camera.
This means that you view the subject through the
same lens as is used to take the photograph.
Continuous viewing (except at the moment of
exposure) is made possible by the use of an
instant-return mirror located inside the body just
below the pentaprism. Since the picture you see in
the viewfinder is the same as the one recorded on the
film, parallax is completely eliminated. The view-
finder remains bright during AE operation, because
through-the-lens metering (TTL) is performed with
the lens at maximum aperture. Focusing is made
easier by a split-image/microprism rangefinder. You
rotate the focusing ring while looking through the
viewfinder until the point where the divided image
of the subject on the split-image focusing screen can
be seen correctly matched in the center of the
viewfinder. The subject snaps into sharp alignment at
proper focus. For a subject not having straight-line
forms or with indistinct outlines, you have the
choice of using the microprism ring around the
split-image focusing screen. The microprism shatters
out-of-focus images very well and snaps into sharp-
ness at the precise point of focus. When using certain
lenses (such as macro or super-telephoto), the
