p.1 #2Has Sirui quietly stepped back from Nikon Z ?
well, from G/AI:
Sirui's new Swift 20mm f/2.4 and 40mm f/2.2 autofocus lenses are actually listed or planned for Nikon Z-mount alongside Sony E, Fujifilm X, and Leica L mounts in official announcements, though availability can vary by region or initial rollout phase.
However, if you are seeing missing Z-mount options or recent pull-backs, it is tied to an ongoing legal and patent dispute between Nikon and third-party Chinese lens manufacturers.
• Nikon Patent Lawsuits & Warnings: Nikon has taken aggressive legal action and filed lawsuits (such as the action against Viltrox) regarding patent infringements on the Nikon Z-mount technology.
• Preemptive Pullbacks: Following these legal moves and warning letters sent to companies like Sirui and Meike, several third-party brands temporarily or partially withdrew or delayed their Z-mount autofocus offerings in certain markets (like China's Taobao platforms) to re-evaluate licensing, channel management, or legal exposure.
