I have a Metabones Canon-to-Sony adapter with interior flocking, which I have been using with a Sony A7II for over a year without any apparent flare issues not caused by the lenses themselves. Recently I discovered a flare situation with the Canon 24mm ts-eII and this adapter, with a type scene I have encountered many times before (no very bright light sources or any light sources just outside the field of view) and encountered flare that went away when I put the lens on a Canon body for the shot; so the flare was clearly not due to the lens. The flocking inside the Metabones adapter is fine and the Sony body seems to work fine otherwise. Anyone else encounter this sort of thing with this equipment?
