"STM" stands for stepping motor.
Features
1. The Image Stabilizer gives the equivalent effect
of a shutter speed four stops faster*
1
.
This function provides optimal image stabilization
depending on shooting conditions (such as
shooting still subjects and following shots).
* Only the following cameras are compatible with
EF-S lenses (as of June 2012):
EOS 7D, EOS 60D, EOS 50D, EOS 40D, EOS
30D, EOS 20D, EOS 20Da, EOS REBEL T4i/650D,
EOS REBEL T3i/600D, EOS REBEL T2i/550D,
EOS REBEL T1i/500D, EOS REBEL XSi/450D,
EOS REBEL T3/1100D, EOS REBEL XS/1000D,
EOS DIGITAL REBEL XTi/400D DIGITAL, EOS

2. Aspherical and UD lens elements result in
outstanding image delineation.
3. Electronic manual focusing made possible
by electronically detecting the rotation of the
focusing ring.
4. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
5. Circular aperture for producing beautiful
softfocus images.
6. Improved Movie Shooting Functions
• The EF-S18-135mm f/3.5-5.6 IS STM is
equipped with dynamic IS, effective when
shooting while walking since it expands the IS
range.
• Stepping motor achieves quiet, smooth Movie
Servo AF.

2
*1: Based on [1/(focal length 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 x1.6)]
second).
*2: Function compatible with the following camera (as
of June 2012):
EOS REBEL T4i/650D
