The Japanese company Shoten launched a new full metal ring mount replacement for E-mount cameras. It works just like the recently launched Fotodiox metal ring mount (here on Amazon). The ring is nt needed for the newer A7s and A7II cameras. And I guess all future new E-mount cameras will come with stronger mount rings too.
