Given the conflicting and wrong information circulating online, I contacted Viltrox directly and asked them about their 135mm f/1.8 LAB lens coming for other mounts. This is the response I got:
“Fuji X mount? I haven’t heard anything about Fujifilm X mount, but Nikon Z mount will be launched in the future, though the timeline is uncertain.”
The E-mount version of the lens is currently available at Amazon, B&H Photo, Pergear, and Viltrox store.
The Viltrox AF 135mm f/1.8 LAB FE lens for Sony E-mount is now available for pre-order
