We’ve mentioned previously that an RF 24-70mm f/2.8L IS will be coming sometime in 2019 for the Canon EOS R system. We’ve also been told that an EF version of such a lens is also in the works.
We’re now told that the RF version of the 24-70mm f/2.8L IS will come ahead of an EF version. Though the source did say that it’s possible the EF version never comes, it may come down to how well the EOS R system cameras are received in 2018 and 2019. We do expect to see an entry-level EOS R camera, as well as a “pro” body.
The EF lens lineup is going to take a backseat to the RF line for the foreseeable future.
