I noted on another thread that I have someone who has offered to make a focusing helicoid for the lens if neither of the other two adapter work. I have a Fotodiox and a Novaflex coming - both are supposed to be guaranteed infinity.


unfortunately, guaranteed infinity typically means they guarantee that a lens with a helicoid will reach infinity rather than not being able to focus all the way too infinity. this is not the same as having infinity correspond to the infinity mark on the focus dial of the lens, which is what you need from the adapter for things to work. most adapter manufacturers typically design to allow focus past infinity (adapter too thin) so manufacturing slop on sony's part, the lens manufacturers part, or the adapter makers part doesn't result in not being able to reach infinity (adapter too thick).
