Sony Announces New Camera - A7Riii

As for PC-E compatibility, consider it done.

Maybe not, unless you only want to shoot wide open: Gear Review: Vello Nikon to Sony E-mount AF Lens Adapter

Perhaps you didn't read the link I sent. This should help. The Vello adapter is compatible with Nikon E-type lenses.

 

Vello Select Nikon F Lens to Sony E-Mount Camera LAE-SE-NFV5 B&H

Perhaps you didn't read the one I posted? Brian Smith went to B&H and tested each of the lenses he mentioned in that post. And at the time of that post, the then current firmware version of the adapter only permitted shooting PC-E lenses fully open (and I haven't found any newer information to the contrary). PC-E lenses don't operate exactly the same way as other Nikon E lenses (the 19mm PC being the exception). In any case, specifically for Nikon PC-E lenses, your statements about using a simple adapter and just adding a few contacts certainly clash with reality.

The Vello adapter is specifically for E lenses. A much simpler, cheaper adapter will have manual aperture control for D and G lenses, albeit manual focusing. If there is an aperture ring, set the adapter to the smallest opening and use the setting ring on the lens. For G lenses, you have only rough control over the aperture via the adapter. Canon lenses are fully compatible, for both aperture and auto focus.

 

I would not recommend buying a Nikon lens specifically for a Sony ILC. If you already have one, presumably you have a Nikon camera with full compatibility. it's okay to use an adapter for the Sony, but you may find the results are disappointing compared to a Sony/Zeiss lens. PC lenses are special, and not exactly suitable for action regardless of the body. Since Sony does not make a native PC lens, feel free to experiment. Perhaps the PC-E version should be eschewed in favor of an older model.

 

For static subjects, I find I can use focus stacking to good effect. Unlike with a tilting lens, parts of the subject do not have to be in the same plane.
