We have been instructed that SIGMA is actively engaged on an RF mount lens roadmap and can announce their plans someday in early 2020, I’d suspect an announcement forward of CP+ in February can be the perfect time to accomplish that.

Apparently distributors have obtained some early details about SIGMA’s plans, however our supply on this one didn’t need to reveal any extra info.

It can be nice for the EOS R system if SIGMA will get on board early with compelling lenses.
