Re: Is anyone experience "back button focus" issue like this?

Hi Ulrik, yes, that's what I experiencd.

I am using 56.2 too. Maybe this combination will cause the issue. Here is a video I made. You can see the first few second, M mode, when I press the shutter button. You can easily see the focus jump few cm.

At the same time, I can hear there is a sound, kind of motor rotating. But it sounds different as the sound during auto focusing.

Here is the video. I did few times of BBF test,  the first time has issue.
