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.
消息如上,意思就是說,EOSM新版韌體將改善 one shot AF的速度快 2.3 倍,
大約在2013年六月底就有新韌體可更新了!
