刚刚在外网看到的，不知道此时的设计范围有多广，下面是我根据百度翻译，稍微修改过来的

    最近，佳能（海外）承认了EOS 7D MARK IId的自动对焦问题。但却没有正式告诉广大消费者，本次问题佳能是否可以通过固件更新或还是需要消费者带着相机去服务中心解决。但目前有消息说通过固件升级解决这个问题的可能性很大，但是问题尚未完全解决。
    没有提及到本次自动对焦的问题是否会影响到所有的新款相机，我们宁可猜测不会是这样。
更多的消息即将到来


    原文：
    We’re told by a couple of people that Canon has internally acknowledged an autofocus issue with the EOS 7D Mark II. No official announcement will be made by Canon until they determine whether or not the issue can be resolved with a firmware update or if it will require the camera to visit a service center. All signs point to the former, but the issue has yet to be fully resolved.There was no mention whether or not the AF issue affects all cameras,and we don’t want to speculate on this either.
    More to come…
