When you want
to
photograph a small animal or
an insect, it's important
to
get close quietly -
without scaring
the
subject. Canon
Macro
Lenses
with USM and inner
focus
let
you photograph
subjects with quiet, rapid autofocus. You'll feel
confident
to
approach
many
subjects that
are
sensitive
to
sound and motion
in
the
big world
around them. You'll
be
able
to
get close and
capture big, bold images of small worlds!
