The adapter does basically what it should, it does not shake, so far so good. However, the Sony-Bayonet is made not quite fit. To get the adapter from the camera must be quite the adapter rumwackeln until the button for releasing at my Alpha 6000 can be pressed. At the first attempt I therefore get slight sweating because I was afraid that the thing no more accidents going on.
Now for something for which manufacturers and adapter can not, but this is still annoying. Even with my Nikon lenses with private aperture ring I can only set the aperture to the adapter and do not have the ring on the lens. This is due to the automatic diaphragm of Nikkor lenses that fully opens when the lens is screwed onto the adapter. The adapter can adjust the aperture but only continuously and has no idea what exactly you use bezel.
