  • Nikon is rumored to be suing the budget lens manufacturer Viltrox
  • The lawsuit concerns alleged infringements of Z-mount patents
  • A hearing is reportedly scheduled for March 2

As an enthusiast of both Nikon cameras and Viltrox lenses, the news of a potential lawsuit between the two is concerning. According to The New Camera, Nikon is taking legal action against Viltrox for purported patent violations related to the Z-mount.

Chinese social media reports indicate that the dispute revolves around “royalties during the temporary protection period of an invention patent.” While it's unclear which specific Viltrox lenses are implicated, speculation surrounds the 135mm f/1.8 LAB, which is significantly cheaper than the Nikon 135mm f/1.8 S Plena – both of which I have tested and found to be exceptional.

The timing of Nikon's lawsuit is not unexpected, as Viltrox has rapidly become a leading third-party lens manufacturer and may be in a position to negotiate any necessary royalty payments.

Nikon Rumors elaborates on the situation, outlining several possible outcomes, including a cease and desist order, reminiscent of the Canon vs Viltrox case in 2022.

Nikon enthusiasts are likely hoping for a resolution that allows Viltrox to continue producing affordable Z-mount lenses. Viltrox's recent autofocus offerings have proven to be high-quality alternatives for Nikon users seeking prime lenses, despite the absence of zoom options.

On the flip side, Viltrox's reputation for reverse engineering lenses without licenses contrasts with other third-party manufacturers like Sigma and Tamron, who secure licenses for their products. This raises questions about the fairness of requiring Viltrox to pay royalties to Nikon.

A potential compromise could see Viltrox continue to release new Z-mount lenses while paying royalties, which would likely increase their prices. In contrast, Sony's E-mount appears to be more open to third-party manufacturers like Viltrox. However, the outcome of this case could significantly influence the future of Viltrox's Z-mount offerings.

'Will my [Viltrox] lens become a brick?' – potential outcomes of the case

Understandably, Nikon camera users with Viltrox Z-mount lenses are anxious about the implications for their current gear. The question, 'Will my [Viltrox] lens become a brick?' has been circulating on Chinese social media.

There are concerns that Nikon might issue a firmware update for its cameras, such as the Z6 III, Z8, and Zf, that could disrupt compatibility with Viltrox lenses. Although there is currently no evidence to support this fear, it has led some users to consider postponing firmware updates until more information is available.

However, it is important to remember that the lawsuit is still speculative and has not yet commenced. We do not know if Viltrox had a license for the alleged infringement.

As a user of Nikon's Z-mount cameras and Viltrox lenses, I hope to maintain the diverse lens options currently available and look forward to new releases from both brands.
