I think we have established that is the current Ultron with LTM adaptor screwed in place.
Fair enough, but the chrome mount in the photo looks alot thicker than a conventional M adapter. But your probably right but I cant see Cosina changing the optical design of the lens but just add an M mount as that has been their usual upgrade, especially when the lens is as good as the 28mm f1.9 is.
