**UPDATE** Nikon has responded to DPReview regarding the reported lawsuit, but stopped short of addressing the matter directly. It did state that it has “always worked with officially licensed partner companies” and that it encourages third-party lens use “from manufacturers licensed by Nikon.” I cannot find confirmation that Viltrox is an officially licensed partner, so read into that what you will.
The word on the social-media street is that Nikon is suing Shenzhen-based lens manufacturer Viltrox, although over precisely what is pure conjecture. Japanese photography news website, Asobinet, picked up the rumor a couple of days ago, with the online source pointing to a licensing-fee dispute between the two companies.
