Beware, however, it has a way of working that I have not yet fully understood ... Apparently stabilization snaps only when you press the shutter or directly when shooting. On the other hand, it does not always work when using the camera's viewfinder.
But this is a great product that effectively did what it is supposed to, at a very good price and better than most known Metabones which has many problems and is 4-5 times more expensive. The only problem, but that's normal, autofocus is slow, but I suggest in this case buying a lens from Sony. And with the tools that focus peaking offers A7S, for example, we made it fast enough to take pictures by manually adjusting the focus. ;)
