Why is each individual lens optimized for shake correction?
Each Canon IS Lens has a unique optical design for specialized performance. So, Canon's optical
correction systems
and control mechanisms are customized for effective positioning in each lens
model.
Canon builds these mechanisms into the lenses to ensure that the optical correction system is
optimized for each individual lens. No matter which Canon lens you use - wide - angle zoom,
telephoto zoom, fixed focal length telephoto,
or standard zoom - you can count on high-precision
camera shake correction
at all focal lengths.

How do large prints show outstanding correction performance?
Nowadays, more and more people are enjoying easy
printing
of large-sized photos using digital SLR cameras
and home printers. While camera shake blur may not
be
apparent in postcard-sized prints, it becomes clearly
visible as print size increases.
Canon's in-lens image
stabilizer accurately compensates for even the slightest
camera shake. That's
why Canon IS Lenses are the
perfect choice for the
growing number of users who
enjoy printing - and displaying - their own beautiful
large-sized
digital photos.
