Metabones Firmware Update For Canon EF Adapter for Better Performance with Sony a7S

Metabones has released an update (V0.32) for the MARK IV Canon EF Adapter which can be done by the user by following the instructions on the download page. It will improve the performance of the Metabones adapter when working with the a7S. I've already done the update and it doesn't seem to improve focus performance as far as I can tell, but will probably prevent the adapter to lose contact with the a7S.
