The SMC Pentax-DA 18-55mm f/3.5-5.6 AL lens is a standard zoom lens for the Pentax K-mount. It is often sold as a kit lens with Pentax digital SLR cameras and has a 35mm equivalent focal length of 27-82.5mm. Its optical formula is made of 12 elements in 9 groups. There are two variants of this lens:

SMC Pentax-DA 18-55mm 1:3.5-5.6 AL (first version of 18-55; LensType=252)
Samsung D-XENON 18-55mm 1:3.5-5.6 AL (Schneider Kreuznach branded variant; supplied with Samsung GX-series DSLRs; LensType=246)

A new optical formula (11 elements in 8 groups) was introduced in 2008 and exists in five variants:

All lenses except the DA L variants provide the Quick-Shift Focus System, providing full-time manual focus while in autofocus mode. The DA L variants also lack a distance scale and are sold without a hood. The hood for non-WR variants is PH-RBA52 while the hood for WR variants is PH-RBC52
