Capture fleeting photo opportunities!
Concentrating on your subject is difficult if the viewfinder image
IS
blurred. When you lose
concentration, you tend to miss small gestures and other momentary photo occasions. Canon's in-
lens image stabilizer gives you a clear viewfinder image, so it's easier to notice and capture such
photo opportunities.

Decisive moments with moving subjects. Canon IS Lenses help you capture the right instant
in an action shot, particularly when using a telephoto zoom lens.
Feel at ease with panning techniques!
When panning, it's not easy to keep a moving subject within the viewfinder's autofocus frame. This
is especially true if the position of the subject varies both vertically and horizontally.
In
such cases,
Image Stabilizer mode 2 in Canon IS Lenses can greatly simplify panning by compensating for
vertical lens movements.
