Canon EF-S 18–135mm f/3.5–5.6 IS

The original version of the lens, the f/3.5–5.6 IS, was introduced in 2009 with a suggested retail price of US$499.99. It is the standard kit lens for the Canon EOS 60D and EOS 7D, and is an alternative kit lens in some markets for the EOS 600D/Rebel T3i.

Canon EF-S 18–135mm f/3.5–5.6 IS STM

A new version of the lens, the f/3.5–5.6 IS STM, was announced on 8 June 2012, alongside the EOS 650D/Rebel T4i/Kiss X6i. The "STM" stands for "Stepping Motor", a new autofocus technology claimed by Canon "to smoothly and silently focus" and "achieve continuous AF while recording video" when used with the 650D (and presumably future Canon bodies).[1] Its suggested retail price was US$549.99 at introduction. It was an alternative kit lens for the 650D, and is now an alternative kit lens for the 650D's successor, the EOS 700D/Rebel T5i.

This STM version, in some markets, is available as a kit lens for the Canon EOS 70D, as is also the Canon EF-S 18–55mm lens in its STM version.
