Patent illustrations for a Viltrox 2.0x teleconverter have surfaced on Nikon Rumors, with ‘Z-Mount’ clearly visible on a couple of images. Should this come to fruition, it would be the first third-party teleconverter for Nikon Z-Mount.

Currently, only two teleconverters are available: the Nikon Z Teleconverter TC-2.0x and Nikon Z Teleconverter TC-1.4x. These optical accessories retail for $599.95 / £599 / A$1,199 and $549.95 / £579 / AU$1,099, respectively, so a more affordable alternative would certainly be welcome.
