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 attach it to the A7 on the lens side and the soft side (it's better than the other way around...) The diaphragm ring is easy to handle. Infinity is maintained. The price is still quite expensive but the manufacturing quality is evident and the results are there: no play on either side of the ring.
