Future Mirrorless Nikon camera may comes with an extra “pellicle” adapter for Nikon F lenses

A newly released Nikon patent discloses their plans to make Nikon F lenses work on their future professional (Full Frame?) mirrorless system camera. A special adapter with pellicle and PDAF module could allow to use Nikon F system with the best possible focus system.

Basically this works like the current Sony LAEA4 adapter.That adapter has a semitransparent pellicle mirror that reflects a bit of light to the PDAF sensor. The downside is that you loose about 1/3 of a stop of light. But that’s negligible in most situation.
