Sony is about to unveil a system to fully utilize the Nikon or Canon on its optical reflex enclosures, eliminating what is one of the obstacles to the mobility between brands in the field, namely being captive of its optics. If it is obviously possible to do this, using adapter ring, this assembly lose the benefit of autofocus. The idea of ??Sony, therefore, is to make the autofocus sensor itself.
To achieve this, it is moving about 18 mm deep in the box, latitude used to achieve development. With such a device, it is possible to mount any optics (the adapter ring is always required) and it will work as its destination box. The difference is that it is the sensor housing that move, not the lens optics.
The Sony A7000 case would be the first manufacturer to ship this technology. The idea is not new: The video below shows a neighbor system on an old silver box Kontax Ax.
