Convenient 18-55mm zoom range
The DT 18-55mm F3.5-5.6 SAM's zoom covers the frequently used 18mm to 55mm range (35mm-
format equivalent: 27-82.5mm), and provides a field of view similar to that of the human eye. As a
result, it is an excellent lens for everyday use, capable of handling everything from snapshots and
group photos to landscapes and portraits.
Aspherical and ED (Extra-low Dispersion) glass elements
Two aspherical elements and one ED (Extra-low Dispersion) glass element are incorporated into
the optics to assure high image quality with excellent contrast and resolution all the way out to the
periphery of the lens. In addition, a circular aperture mechanism is used to assure smoother, more
beautiful background defocusing.
Newly-developed Smooth Autofocus Motor (SAM)
The DT 18-55mm F3.5-5.6 SAM's focusing lens group is driven by a new Smooth Autofocus Motor (SAM)
in the lens itself, instead of a motor in the camera body. Responding instantly to AF drive control
signals from the camera, the motor delivers power with smoothness and precision.
Newly designed rear lens element shade
The designed shape of the rear lens element shade has been updated in the SAL18552 to help
suppress internal reflections and reduces flare and ghost for higher performance and better image
