据说相位对焦需要镜头固件的支持，虽然还没购入XE-2，但提前确认了这个消息，手里有touit镜头的朋友，可以考虑等固件发布后再升级XE-2

Dear,

Thank you for your inquiry and interest in our lenses.

Yes, after the touit lenses for Fujinon with the X-mount we will also release an update for the XE-2 in the near future. This will be presumably available in January / February 2014.

Hoping to be of service to you. Do come back if you need further information.

Best regards,

Filomena
