Autofocus Speed Boost
Further enhancing the performance and utility of the EOS M, Canon also announces today a firmware upgrade that boosts the AF shutter speed, making One Shot AF up to 2.3x faster1. The new firmware delivers improved performance as a result of a reworked AF Drive Control System and Canon encourages all existing users of the EOS M to download the new firmware version 2 once it becomes available at the end of June 2013.
