Nearing Human vision or surpassing it: the interchangeable lens.

The human eye is the all-purpose lens:
it focuses precisely on whatever it
chooses. Interchangeable lenses make
it possible for the photographer to
come close to duplicating — even sur-
passing — this capability. That's why
Canon provides almost 60 different
inter-changeable lenses for just as
many different applications. Standard
lenses give a natural-looking pers-
pective which closely approximates
human vision. These have large aper-
tures, which make photography in
dimly lit rooms as well as low-light
outdoor scenes possible. But for the
really exceptional shot — a soaring
bird, or the minute details of an insect's
wing — standard lenses won't suffice.
Distant subjects require telephoto
lenses, whereas subjects almost too
small to see call for macro lenses.
When a broad field of view is the
target, wide-angle lenses accomplish
the task. Near or far, great or small,
different lenses are needed for
attention-getting pictures.
