According to a report from Canon Rumors, Sigma is ‘actively working on an RF-mount lens roadmap’ and is expected to announce its plans sometime in ‘early 2020.’

Canon Rumors’ report, which comes from an unnamed source, goes on to say that distributors have received early information regarding Sigma’s plans, but no specific information regarding potential lenses or launch dates was divulged.

Canon Rumors only ranked this rumor a ‘[CR2]’ (with [CR1] being very unlikely to happen and [CR3] being most likely to happen), so while it’s down the middle in validity it’s worth taking with a grain of salt. Still though, Canon Rumors suspects the announcement would be made ahead of CP+ in February if it were to be made at all.

Sigma offers nearly all of its EF-mount Global Vision Lenses for Nikon’s F-mount as well, so it wouldn’t come as a surprise if this purported lens roadmap from Sigma would also apply to Nikon’s Z-mount cameras too, considering the similarities in mount designs. However, much like the roadmap itself, this is purely speculation.

We have contacted Sigma for a comment and will update this article accordingly if we hear back.
