The 10x optical zoom lens
consists of 11 elements in 
9 groups (including one
aspherical lens).
Only sixty years of Canon’s optical heritage could
create the PowerShot S1 IS’s amazing 10x optical
(32x combined) zoom lens. Using specialist lens
expertise and countless patents on zoom lenses,
Canon has developed an amazing compact and
retractable lens equipped with a shift-type Optical
Image Stabilizer and Ultrasonic Motor.
Advanced lens technology.
ULTRASONIC MOTOR (USM)
For super-fast, near-silent zooming* action inside
the PowerShot S1 IS’s lens, Canon has used its
renowned Ultrasonic Motor technology. It’s ideal for zooming in
when making movies, as the almost-silent motor won’t be heard on
the audio. It’s also perfect for quick compositions, since its zoom
speed means you get your desired shot before the moment passes.
* Level of speed and noise depends on whether you’re in movie or still mode.
10X OPTICAL ZOOM 
The PowerShot S1 IS with its 10x
optical zoom (38-380mm in 35mm
format) and maximum aperture of f/2.8 to
f/3.1, allows you to shoot a variety of scenes.
From landscapes to nature photographs to
sports events and more.
OPTICAL IMAGE STABILIZER (IS)
The PowerShot S1 IS has an Optical Image Stabilizer (IS)
where gyros within the lens detect any camera shake which
can cause a blurred image. Perfect for when a tripod is not available,
the IS lens group moves up, down, left or right to slow down the
amount of shake. The result is a clearer and sharper image even at
slow shutter speeds and in low light conditions.
