From Canon New Zealand: Firmware Upgrade Boosts AF Speed by up to 2.3x
Further enhancing the performance and utility of the EOS M, Canon also announces today [June 6] a firmware upgrade that boosts the AF shutter speed, making One Shot AF up to 2.3x faster*. 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**.
"The EOS M is designed for people who want to spontaneously capture the great moments in life, in the highest quality, without missing a beat." says Robert de Jeu, Senior Product Manager – Technical Imaging Specialist, Consumer Imaging at Canon New Zealand. "With this firmware upgrade, Canon has responded to the feedback from the community by providing them with an increase in AF speed, enabling users to capture high-quality images quickly. What’s more, with the introduction of the EF-M 11-22mm f/4-5.6 IS STM lens, they are able to get even more of the fun around them into the frame." Footnotes
