Features
1. The Image Stabilizer gives the equivalent
effect of a shutter speed four stops faster*.
This function provides optimal image
stabilization depending
on shooting conditions
(such as shooting still subjects and following
shots).
2. Aspherical and UD lens elements result in
outstanding image delineation.
3. The zoom ring can be fixed to keep the lens
at the shortest point.
4. A truly round aperture hole results in a nicer
background blur.
* Based on [1/(focallength x 1.6)] second. Generally,
it requires a shutter speed [1/focal length] second or
faster to prevent camera shake
(in 35mm format.
With
an EF-S lens, it would be [1/(focal length x
1.6)] second).

and taking pictures.
