Last week a bunch of reports hit the web about Viltrox being told to stop producing lenses for the RF mount by Canon. In an exclusive report, German magazine Photografix has received word from Canon Germany about the issue.
It looks like it affects autofocus lenses being made for the RF mount and patent infringement. What the exactly Viltrox was infringing on is unknown. Rokinon continues to sell AF lenses for the RF mount.
From Canon Germany (Google Translated)
“SHENZHEN JUEYING TECHNOLOGY CO.LTD, manufactures auto focus lenses for Canon RF mount under the brand name “Viltrox”. Canon believes that these products infringe their patent and design rights and has therefore requested the company to stop all activities infringing on Canon’s intellectual property rights.”
So what does this mean for the likes of SIGMA and Tamron producing RF mount lesnes? We don’t think this clears much up at all. Until we hear from the “big two” third-party brands or more from Canon themselves, we’re all left wondering.
