I have 4 adapters and all of them the mounts where lose. 2 Metabones 1 Novaflex and the Sony adapter I had to tighten down every one of them with a small Phillips head. This could lead to many issues. These are all brand new. These are all on the lens side of the adapters . Get your screwdrivers out and check them.
