Canon Announces EF-M 11-22mm f4-5.6 IS STM Lens and Firmware 2.0 for EOS M

Canon EF-M 11-22mm f4-5.6 IS STM

Canon today announces a new lens for its EOS M mirrorless system, the 11-22mm f4-5.6 IS STM wide-angle zoom. Together with the 11-22mm, which is equivalent to an 18-35mm lens on 35mm full-frame, Canon also announces firmware 2.0 for its (currently only) EOS M mirrorless camera. The firmware promises to boost AF speed, and fixes a bug that causes the EOS M to freeze when the new 11-22mm lens is used. Details after the break.

Canon EOS M firmware 2.0

The firmware upgrade will boost the AF shutter speed, making One Shot AF up to 2.3x faster. It delivers improved performance as a result of a reworked AF Drive Control System and will become available at the end of June 2013.

Further improvements are:

– When using FlexiZone Multi AF and the EF-M 18-55mm f/3.5-5.6 IS STM Lens. Speed improvement is dependent upon shooting conditions and lens.

– The firmware upgrade also corrects a rare phenomenon that causes the EOS M controls to become unresponsive when the new EF-M 11-22mm f/4-5.6 IS STM lens is used.
