Sirui, Meike Pull Nikon Z-Mount Lenses from Chinese Stores Amid Legal Fight

Sirui removed all Nikon Z-mount autofocus lens listings from its Taobao stores and from most Chinese distributors beginning March 2, 2026, and Meike followed shortly after with a temporary delisting that the company described as “inventory optimization,” saying it was “re‑inspecting quality and coordinating distribution channels” and that Z‑mount lenses would “return by the end of March.” The removals happened as Nikon pursues patent infringement claims tied to the Z‑mount ecosystem, a dispute that public reporting first surfaced in January and that several accounts tie to a formal court step around March 2 at the Shanghai Intellectual Property Court.

The legal fight centers publicly on Viltrox, which has been identified as the first defendant. Viltrox said it is “working closely with our legal advisors to review and address the situation through appropriate legal channels,” and added that its product roadmap “remains unaffected by the legal matter.” Nikon, when contacted by outlets, “reiterated its stance from January,” though the exact wording of that stance was not reproduced in the reports available at the time of publication. Sirui has not issued a direct corporate statement in the reporting reviewed here explaining its removals.

Retail availability shows a split by region and channel. The delistings targeted Chinese e‑commerce channels, notably Taobao and domestic distributors; at the same time, Sirui and Meike Z‑mount lenses were still listed on international retailers such as B&H Photo and Adorama and on some company websites, depending on region. That regional gap could leave buyers in mainland China facing immediate shortages while buyers elsewhere still find stock.

Legal and technical observers have weighed in on what the dispute might mean. Patent attorney Dr Bernard Dippenaar noted that third‑party makers can build Z‑mount products but permission is required to use patented technology, and Professor Bob Newman pointed out there is not one single Z‑mount patent, suggesting the dispute could hinge on specific elements such as electrical contact points. Industry analysis circulating in the community also frames Nikon’s enforcement as focused on autofocus lenses rather than adapters or teleconverters, and unrelated to the older F‑mount.

Market implications are straightforward and fast-moving. Licensed third‑party Z‑mount makers such as Tamron and Sigma are reported as unaffected because of formal licensing arrangements, while unlicensed makers tied to the current dispute — Viltrox, Sirui, Meike — face uncertainty that analysts say could push demand into the used market. Industry trackers outline two paths: an early Nikon court win that could prompt wider takedowns and stricter enforcement, or a negotiated licensing settlement that would institute royalties and pause new sales while terms are hammered out.

What matters next is paperwork and timing: the actual Shanghai Intellectual Property Court filings, any preliminary injunctions, and formal statements from Nikon, Sirui, Meike, and Viltrox will determine whether Chinese storefronts remain frozen or relistings resume by the end of March as Meike promised. For Z‑mount shooters, the immediate takeaway is concrete: inventory has moved offline in China while licensed options from Tamron and Sigma remain the safer bet until the court record is public.
