A new Tokina 400mm f/8 IIS mirror/reflex lens for Nikon F and Z mounts will be announced soon according to Nokishita. It is not clear if this will be a replacement for the current Tokina SZX 400mm f/8 reflex MF lens (pictured above) that uses interchangeable lens mounts or a completely different new design (see previous coverage).
