Canon EF-M 11-22mm f4-5.6 IS STM lens review: good all round performerBy Kevin Carter - Tuesday September 10 2013 Lens Review
Although not officially released in the US, as the equivalent to an 18-35mm the new EF-M 11-22mm f4-5.6 IS STM is an essential addition to the EOS M system. Read on to find out how well it performs in our labs.
As with their EF-S counterparts, the EF-M series are designed for the smaller APS-C image circle and for the EOS M series bodies in particular. This is limited to just one model presently, which takes its name from the system, the 18-MPix EOS M.
Introduced earlier this year this new wide-angle zoom lens is the equivalent to a 18-35mm field of view and is equipped with both a 3-stop “Dynamic” stabilizer built-in and the firm’s new linear stepper motor technology for less intrusive focusing with contrast detection AF during video-capture.
It also features a full-time manual focus option and a new retracting mechanism (and lock) for improved portability. As for the optical construction, it has 12 elements in 9 groups, focuses to just 15cm and weighs 220g. The lens hasn’t officially been released in the US, but it is available now in Europe at 406,50 Euro (around $449 after deducting sales Tax).
