Canon has confirmed that they will be focusing on the new RF mount in the future and unless the market demands it, there won’t be any new EF mount lenses.
This comes as somewhat of a surprise as the newly announced 1D X mark III uses the EF mount just like all their flagship DSLRs. Some might argue that the EF system is already complete and there really isn’t a need for any new lenses short of upgrading some of the current line up.
The company feels that they need to focus on the RF mount launched last year with the EOS R camera.
To date we’ve launched ten critically acclaimed lenses, and as it’s a new system we plan to continue this, launching more RF lenses while still fully supporting the EF lens system. And of course, should the market demand it, we are ready to create new EF lenses. But for now, our focus is on RF.
There are rumors circulating that we can expect some consumer-grade RF lenses soon as the current offerings are quite expensive. Currently, users who want cheap glass for the EOS R have to resort to using an adapter for their EF lenses and although it works really well, it is not quite perfect as it adds unnecessary weight and volume to the system.
The company did make it clear that it is not ‘abandoning’ the EF mount but only changing focus for the near future to get the RF system up to speed with its competitors.
