I will add I am having the same problem using the camera for stills since it was designed and built for both mediums.
Also, did try a Nikon DX 18-55mm and in manual mode everything works like it should. Have used these Zeiss lenses on a RED ONE, Panasonic AF100, 5D MKii and others, but of course they don't read the CPU data like the Nikon is supposed to without a smart adapter. Perhaps a Nikon firmware issue? Anyone else have a zf.2 they can try on their d800?
