>>3049916When putting a heavy lens on a mirrorless cameras, you really should be holding the lens and not the body. Sony for some reason decided to make the mount on the body out of plastic, and that plastic mount is affixed to a plastic frame. A great example of this would be the 70-200 where I'm certain you'd stress the body and mount on anything but an A7RII.
I doubt your 50 1.7 will do any damage, but if you throw an old 70-200 on there, then you may need to start holding the lens instead.
