Canon L2 - Manual (Page 21)

On the Canon Camera focusing and composing can be
done at the same time. When you look through the Range-
Viewfinder Eyepiece (25), you will see two images. By releasing
the Lens Focusing Lever and rotating the lens barrel, the
two images of the object you are focusing upon will coincide.
At this point of coincidence your camera is
in focus
for the
object you are about to photograph.
All Canon Lenses are coupled with the Canon Range-View­
finder mechanism.
