On 14 February 2017, the 18–55mm f/4–5.6 IS STM was announced alongside the EOS 800D/Rebel T7i, 200D, and the 77D. At introduction, it was offered as a kit lens on both the 700D and 100D it has since become one of two alternative kit lenses for the 70D. The STM is also the first 18–55mm version with an internal focusing design. It has a different optical formula from that of any previous Canon 18–55mm lens, and includes Canon's STM ( stepping motor) technology, claimed by the company to offer quieter continuous autofocus while shooting video when attached to bodies that have Canon's hybrid autofocus sensor technology. On 21 March 2013, the 18–55mm f/3.5–5.6 IS STM was announced alongside the EOS 700D/Rebel T5i and 100D/Rebel SL1. On 7 February 2011, the 18–55mm 1:3.5–5.6 IS II was announced to be bundled with the EOS 600D and 1100D. The lens featured improved optical quality over previous versions and added image stabilization. On 20 August 2007, the EF-S 18-55m IS was announced along with the EOS 40D.
Barrel distortion becomes quite noticeable at the wide-angle setting and chromatic aberration (purple fringing) is common. Generally, however, this version of the lens is soft and must be stopped down to gain acceptable sharpness. The lens body has a plastic construction, including the lens mount.
