Nikon Zf, boring mirrorless camera, plastic, dials, but released alongside with an FTZf adapter compatible only with Zf ($999 extra). Adapter would enable aperture control for AI-S, autofocus screwdriver for AF-D, and a built-in mirror.
Zf EVF would be removeable and an accessory pentaprism would take its place when camera is equipped with the FTZf adapter, allowing TTL view.
