Sony E 10-18 mm f/ 4 OSS Lens Service Manual (en)

3x zoom with attractive pricing, compact size, and low weight
The DT 18-55mm F3.5-5.6 SAM is a 3x (approx.) zoom lens designed specifically for use with 
α DSLRs 
that have an APS-C type sensor. It is exceptionally light and compact, with a weight of only 210g 
(approx.) and dimensions of 69.5mm (max. diameter) x 69mm (length) that make it very easy to 
handle and carry.
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 
0.25m minimum focusing distance, 0.34 maximum magnification ratio
With a class-leading minimum focusing distance of just 0.25 meters and a maximum magnification 
ratio of 0.34, the DT 18-55mm F3.5-5.6 SAM can also be used to take macro close-ups.
