Although Sony has now refilled with good lenses (Zeiss), but now and then I would not miss the high-end quality and the crop factor of my Nikon lenses. These are all quite caliber, and if I have the accreting to the petite A6000, then I'm glad that such a zero-backlash Qualotätsmechanik like the NOVOFLEX adapter connects.
As well known, electronics will not be transmitted, the shutter is 'pushed' by hand to feel the blue ring of the adapter and the Schaärfe - well, the einzustelln fail at the Alpha, is thanks to which many auxiliary possibilities now really no problem.
Update: In the meantime I use the adapter also to a A7II, so on a full frame camera. He is probably more frequently used in future, because the A7MarkII offers due to the stabilization in 5X (!) Body almost to say you populate with other, already existing non-stabilized quality glasses.
The adapter will not budge and also meets in conjunction with the VF-Sensor his duties excellent. I can only strongly recommend to use the NOVOFLEX if necessary, it is undoubtedly high-end.
