I'm having a very strange problem with my Viltrox EF-M2 adapter. It "disconnects" from my camera (GH5/G85) when I take a picture with autofocus on my Canon 70-200mm f/2.8 II or my Tamron 24-70mm f/2.8. So far it seems to work fine on my Sigma 18-35mm f/1.8 though (which also seems to be the only lens that people have when I tried searching if anyone else has the same issues).
What I mean by "disconnect" is that it will lose connection momentarily (like if I am twisting the lens off slightly), take the picture, and then "reconnect". Sometimes it'll lose the electronic connection completely (no AF/IS) so I'd have to flip the AF/MF switch on the lens to actually enable the AF/IS (or else turn on/off the camera). Other times it reconnects fine.
The image will shift due to the "disconnecting" (since there isn't any more image stabilization) and will cause the image to be blurry. Has anyone else experience this problem?
I uploaded a video showing the problem here:
