I f " p t o
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!
