Good hardware
The ring was used to attach a Tamron 70-200 F/2.8 in A-mount to my A7s in an E-mount. Quite difficult to connect it to the A7 on the lens side and on the soft side (it's better than the other way around...) The membrane ring is easy to handle. The infinity is preserved. The price is still quite steep, but the build quality is evident and the results are there: no games on either side of the ring.
