Canon has released the anticipated free firmware upgrade, which improves autofocusing speeds for its EOS M compact system camera.

Thanks to a reworked AF Drive Control System that boosts AF speed, the new firmware makes One Shot AF up to 2.3x faster when using FlexiZone Multi AF and the EF-M 18-55mm f/3.5-5.6 IS STM 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. The new firmware is available for downloading now at
